Series L10
Fusible &
Non-fusible
Disconnect
Switches
Sprecher + Schuh’s L10 series
of fused and non-fused
disconnect switches comply with service entrance
requirements. This family
of rod operated switches
is suitable for applications
that require small panel
space and superior short
circuit protection.
Big performance in a small
package
Maximum protection for
downstream equipment
L10 switches are engineered to provide excellent short-circuit protection
for downstream equipment. These
switches accept the latest small-dimension HRCI-J and HRCII-C fuses. This
Type 2 protection limits let-through
currents to levels specified for IEC
equipment, and ensures that when the
short circuit is cleared, the device will
be operable.

Common parts reduce
inventory
Universal auxiliary contact blocks fit
on all frame sizes, reducing inventory.
In addition, all 30 and 60A switches
use the same operating handles and
shafts, ditto for the 100, 200 and
400A frame sizes. On-board fuse
carriers also eliminate the need for
extra components while reducing
panel space requirements.
Comprehensive standards
and approvals
L10 disconnect switches conform to
UL 98 standards (100-400A switches)
and UL1087 standards (30 & 60A
switches); are UL Listed, CSA and are
designed to meet IEC 947-3, and applicable NEMA requirements.
L
Disconnect
Switches
L10 disconnects are rated to 400A
and can be operated at up to 600V.
They protect motors up to 250HP
(@460V). The L10 may be installed
on circuits capable of delivering up to
100,000A of short circuit fault current; levels typically found in modern
industrial facilities. This performance
comes in a small package, leaving
room for additional branch circuit
components within the panel.
The L10 series is suitable for use in
service entrance applications. Further
insuring safety, line-side terminal
shields are standard on all L10 disconnects. Non-fused switches (30 &
60A) feature “dead-front” construction
while fuse covers are available for all
devices, preventing contact with live
parts.

Single Motor Applications
Section 430-110 Paragraph (a) states that the disconnect switch must
have an ampere rating of at least 115% of the full load current rating of
the motor.
➊Motor 2 is not included in the total since it cannot operate simultaneously with the
other motor, therefore, the disconnect switch must be rated at least 72A (1.15 x
62.6).
Example 1: for a motor with a full-load current of 22A, the disconnect
switch must be rated at least 25.3A (22 x 1.15).
Consider now the locked-rotor current analysis for the same application:
If the disconnecting means under evaluation is rated in horsepower, the
selection of the disconnect switch is even more straightforward; a disconnect switch must have a horsepower rating equal to, or greater than the
horsepower rating of the motor at the applicable voltage.

126.0 (simultaneous) ➋
Motor 4

If the disconnect switch is rated in horsepower, and UL Listed, UL Component Recognized, or CSA Certified, it will meet the requirements for
the 115% full-load current rating stipulated by the NEC.
Other
The individual full-load current values are to be selected from Tables
430-148, 430-149, or 430-150 and the locked-rotor values are to be
from Table 430-151.
The equivalent single motor full-load current is the sum of the simultaneously operating motor full-load currents and the rating in amperes of
the other loads operating at the same time. The equivalent locked-rotor
current is the sum of the simultaneously started motors’ locked-rotor
currents and the full-load currents of the remaining operating motor and
non-motor loads.

(7.6 FLA)

Motor 1
Combination Load Applications
Section 430-110 Paragraph (c) addresses the rating of the disconnecting
means for combination loads. This paragraph essentially requires that the
loads that “may be simultaneously on a single disconnecting means” be
combined to provide equivalent full-load and locked-rotor currents for
what is then to be considered as a single motor for the purpose of selecting the appropriate disconnecting means. This means that it is necessary
to identify the particular combination of connected loads which can be
operating simultaneously and will result in the maximum full-load and
locked-rotor current sums.
SSNA9000
Consider the following 460V application:
7.0 (simultaneous)
302.6 (simultaneous)
➊Note again that Motor 2 cannot operate simultaneously with the other loads.
➋The largest equivalent locked-rotor current occurs when motors 3 and 4 start
together while the other loads marked “simultaneous” are already operating. Since
Motor 1 is not starting with Motors 3 and 4, its full-load current will be added to
the total instead of its locked-rotor current.
Table 430-151, which provides the correlation between locked-rotor
currents and HP ratings, shows that a 40 HP rating is the equivalent for
302.6 locked-rotor amperes.
Therefore, the disconnect selected for this application must have a current rating of at least 72A and a HP rating of at least 40 HP. In this case,
an L10 disconnect switch rated for 100A and 60 HP at 460V would
be an appropriate choice. What can be seen from this analysis is that,
depending upon the number of motors that can start simultaneously,
the actual size of the required disconnect is sometimes determined by
the equivalent full load current (72A) and other times by the equivalent
horsepower determined from the locked-rotor analysis (40 HP).
Discount Schedule B-7

L
Disconnect
Switches
The requirements for properly sizing a disconnect switch are dependent
on the type of application. The NEC refers to two types of applications:
single motor and combination loads. A combination load consists of an
application where two or more motors are used together or where one or
more motors are used in combination with other loads, such as resistance
heaters.
The disconnecting means shall have a current rating equal to or greater
then 115% of the equivalent single motor full-load current and have a
horsepower rating equal to or greater than the horsepower rating determined from the equivalent locked-rotor summation.
L10
General
The requirements for disconnect switches used in motor branch circuits
rated 600V and less are defined in Article 430, Part H of the U.S.
National Electrical Code (NEC), NFPA70. Canadian Electrical Code
(CEC) requirements are very similar in the area of motor branch circuit
disconnect requirements. For simplicity, we will treat the NEC and CEC
requirements as being the same – and reference specific sections of the
US National Electrical Code.
