• Visible blade construction

• Door that opens greater than 180º

• Quick-make, quick-break mechanism

• 200% optional neutrals (100-600 Amps)

• All copper current-carrying parts on heavy duty switches (except wire grips)

Ratings

• 30-1200 amps

• 240 and 600 volts AC

• 250 and 600 volts DC

• 200 AlC for heavy duty switches

• Design E horsepower rated

• Suitable for use as service equipment

• Provisions for CSA/UL Class T, R, J, L and H fuses

• 12X overload rating that exceeds industry standard of 10X

One Tough Switch: Siemens Type VBII Safety Switch

closed in operation

Siemens now offers a complete line of enclosed switches featuring unique and innovative designs that are unparalleled in the industry.

Siemens Heavy Duty Switches

Feature a Time-Proven Design

Like the time-proven Vacu-Break design, the Siemens VBII doublebreak switching action breaks the arc in two places. This reduces heat generation and increases switching speed by doubling the breaking distance. The result is enhanced performance and increased longevity.

We also provide the most visible blade design available today. Unlike conventional knife blade switches, the blades are self-aligning to ensure positive contact. In addition, they have no wear and friction point since the “electrical hinge” has been eliminated. The result is a very fast, positive and reliable switching action for even the most severe applications.

One Tough Switch:

More Rugged and Durable in Demanding Applications

Siemens engineers tackled the problem of designing a switch that would stand up under the most demanding industrial conditions, such as those in steel mills and mining operations. These environments require a switch that must work reliably and safely in the midst of falling liquids, airborne fibers, dust, metal particles, coolants and other contaminants.

Tested and Retested

All Siemens safety switches have been tested not only to meet but to exceed all CSA/UL requirements.

These tests include those for general purpose enclosed switches and those designed for more specialized purposes where applicable.

The result is a rugged, reliable design that will provide superior performance in a wide variety of applications.

Special Application 4 & 6 Pole Switches

Application Features

4 & 6 pole switches are commonly used as a disconnecting means for two-speed, two-winding motors.

Fused switches provide both over current and short-circuit protection.

Non-fusible switches normally provide a local disconnection means for two-speed motors, which are remote from their motor controller.

4 pole switches are also used in

3-phase, 4-wire circuits when a switching neutral is required.

All 4 & 6 pole switches are service entrance rated.

• Visible blade, double break switching action

• Highly visible ON/OFF indication

• Defeatable dual cover interlock

• Padlockable in OFF position

• All copper current carrying parts ➀

• Tangential knockouts (Type1,

4-pole switches)

• Type 12 & 4X switches are provided with an equipment ground kit as standard

Description

4 & 6 pole switches are available in

30-200A ratings and in both fusible and non-fusible versions; 4-pole switches are supplied with either

Type 1 or Type 12/3R enclosures.

6-pole switches are available with either Type 12/3R or Type 4X stainless steel enclosures.

Double Throw Switches

Description & Application

Double throw safety switches are intended to transfer loads from one power source to another. All twoand three pole fusible double throw switches are suitable for use as service equipment. All are CSA/UL listed. Switches are rated for use on systems up to 10,000A when protected with Class H fuses or

200,000 when protected with

Class R or Class T fuses ➁ . They can also be used to connect a single source of power to either of two loads. In this application it is necessary to field modify fusible switches so that the fuses are on the load side of the switching mechanism.

A cover interlock is provided on all ampere ratings. The operating handle may be padlocked in the

OFF position.

Fuse Application and Selection Data


Siemens enclosed safety switches are designed for fuse versatility.

Although Siemens is not a manufacturer of fuses, once the type of fuse needed for a particular application is determined, it’s easy to select an appropriate switch.

The proper fuse type for the application is selected using the following parameters:

• Voltage requirements

• Conductor ampacity

• Horsepower requirements

• Maximum available RMS fault-current

• CSA/UL fuse class when specified

The compatible fusible safety switch is selected following these parameters:

• System voltage requirements

• Fuse amp ratings

• Available fault current

• CSA/UL fuse class

• Environmental conditions

• Number of poles required

One-Time Fuses

One-time fuses are standard for use in situations calling for 1200 amperes or less with maximum voltages for 250 or 600 volts.

Specially designed, current-carrying links are connected to contact pieces at the ends of the enclosure.

When an overload occurs, the circuit quickly opens and the arc is quenched by granular insulating material that surrounds the current carrying links.

Available in all classes.

Current Limiting Fuses

This design offers the highest degree of circuit protection among fuses. Inside, usually copper or silver alloy links are embedded in pure quartz sand between heavy copper end blocks. The special design is fast-acting and interrupts during the first half-cycle of a fault.

This causes a limitation of both fault-peak current and let-through current.

Available in Classes J, L, R and T.

Dual-element Time-delay Fuses

Dual-element fuses may have timedelay designation since these fuses employ two distinctly separate types of elements. One provides overload protection with time delay.

(CSA/UL states that time delay means having a 10-second operating delay at 500 percent of fuse label rating.) The second provides short circuit protection similar to a single-element fuse. Dual-element fuses are most frequently used on motor loads.

Ratings and Test Requirements


Enclosed Switch Load Ratings

The primary functions of a fusible enclosed switch are to carry current continuously, to provide over current and short-circuit protection, to be capable of disconnecting the circuit, and to provide means for mounting fuses. Safety switches may also have other capabilities covered by load break ratings (in contrast with no-load disconnect switches), such as standard and maximum horsepower ratings and the ability to withstand the maximum I 2 t energy let-throughs of fuses.

All Siemens safety switches are capable of continuously carrying their full-rated nameplate current at rated voltage. This capability is directly attainable in no-fuse switches and in fusible switches when the fuses are replaced with copper bars, without exceeding permissible temperature rise.

Fuses are capable of carrying their rated current in open air. Under this condition the fuses will not open and will not exceed permissible temperature rise. When fuses are used in a switch or other enclosure, a higher ambient temperature is caused by the switch heat and fuse-generated heat. Since fuses are thermal acting by design, they will not carry full current rating at higher ambient temperatures.

To assist users of fusible equipment, CSA/UL requires each fusible switch to carry the statement

“Continuous load current not to exceed 80% of the rating of the fuses employed.” Good electrical practice may require even further de-ratings depending on the type of fuse, load, altitude and ambient temperature of the switch location.

Load Break Ratings

All Siemens safety switches are load break rated. The load break rating is assigned by CSA/UL after the switching unit has successfully performed the following tests for general use enclosed switches:

12X Current Rating

In addition to the required CSA/UL overload testing, all Siemens VBII

Safety Switches have been tested at twelve times rated current at 600V

AC to assure compliance to automotive and other heavy industry requirements.


All Siemens safety switches, where appropriate, are horsepower rated.

The assignment of such ratings is made by CSA/UL only after the switching unit has undergone tests to determine its acceptability. In addition, the unit must successfully perform on an overload test series which includes repeated interruption of the locked rotor current of the motor for which it is to be rated as follows:

Most switches have two or more ratings for a particular voltage and current. Siemens safety switches are

CSA/UL listed for design E horsepower ratings. With Siemens safety switches no de-rating is required in most cases. Depending on the switch and its application, various ratings have been achieved. All

Siemens switches include a complete list of the ratings on the inside of the cover.

Horsepower Rating Charts

The number and variety of horsepower ratings that can be applied to a switching unit makes it impractical, in most instances, to list all such ratings on the front of the unit.

Siemens does, however, provide this data by means of a chart on the inside cover.

Horsepower Rating Range

CSA/UL test procedure include ratings up to 500 HP. Siemens safety switch units in appropriate sizes have successfully passed the locked rotor current interrupting test series for ratings through

500 horsepower at both 480 and 600 volts AC and through

50 horsepower at 600 volts DC.

Maximum Horsepower Ratings

The maximum horsepower rating is based upon the largest rating of a time delay fuse: 1) which can be incorporated in the switch and 2) which will permit the motor to be started. Since the fuse has extra time delay, it can hold the starting current of a larger motor longer than a standard fuse.

Standard Horsepower Rating

This rating is assigned to a switch after it has successfully completed the locked rotor test series, on the basis of the largest standard fuse rating: 1) which can be incorporated in the switch and 2) which will permit the motor to be started.

The standard fuse does not have a designed time delay to allow for motor starting currents.

45


Multiple-Voltage


A switch may have additional standard and maximum horsepower ratings for different voltages.

A switch that is horsepower rated at

240V AC or 250V DC may also have horsepower ratings for motors on

120V AC or 125V DC circuits.

Multipole Horsepower Ratings

A switch may have horsepower ratings applicable to the same current and voltage ratings but with fewer poles if the switch is investigated and found suitable for the assigned rating.

Short-circuit Withstandability

UL test procedures for switches and fuses have been expanded to provide realistic standards of performance with respect to clearing high-level fault currents.

These revised standards deal with the control of destructive energy in the shorted circuit. Two types of potential damage are characteristic of high-level short-circuits: mechanical and thermal. Mechanical damage is caused by the electromagnetic force surrounding conductors; thermal damage is the result of excessive current during the fault-clearing time.

The CSA/UL fuse standard defines maximum instantaneous peak letthrough current (lp) and maximum destructive energy let-through (I 2 t) for each fuse (except Class H).

Applications of fuses and safety switches on systems having more than 10,000A are available.

Short circuits require selections of the proper CSA/UL-listed fuses and switches capable of withstanding

I 2 t let-throughs. See chart below for withstand ratings on Siemens switches.

I 2 t Rated

Suitability tests for service with

Class H, R, J, L and T fuses have been conducted. Representative switches with test fuses connected in series with each switch were subjected to I 2 t let-through values in excess of the capacities of the largest fuses acceptable by the switches.

To pass the test, the switch must remain operable after being closed into a high-amp available short-circuit current. The test fuse is sized so that higher levels of let-through current and energy will be reached than would ever occur during normal usage in the field.

See the chart below for I 2 t ratings on Siemens switches.
