MDW Miniature Circuit Breakers
seconds
B Curve
The main characteristic of the B curve is the instantaneous
trigger for currents between 3 to 5 times the rated current.
Therefore, they are mainly applied for the protection of
circuits with resistive characteristics or involving significant
cable distances. For example: Incandescent lamps, showers,
electric heaters and so forth.
Trigger Time
Trigger curves
The MDW miniature circuit breakers meet the B and C trigger
curve characteristics in accordance with the IEC 60898
Standard, enabling their use in the most varied applications.
Minutes
The MDW thermomagnetic circuit breaker was developed for the protection of electrical installation against
overload and short circuit. With currents that vary from 2 to 100 A, the MDW is avaliable with 1, 2, 3 or 4
poles. Thermal and magnetic triggers for protection against overload and short circuit act quiclky in detecting
and extinguishing the failure. It is equipped with a “trip free” mechanism guaranteeing miniature circuit
breaker performance even with the activation lever locked in the “on” position. Special contacts ensure safety
against welding in case of short circuit as well as the arc extinction chamber, which absorbs the electric arc
energy, extinguishing it when a short circuit occurs.
The MDW miniature circuit breakers also have auxiliary contact blocks (1 NOC), supplied as accessories.
C Curve
The main characteristic of the C curve is the instantaneous
trigger for currents between 5 to 10 times the rated current.
Thus, they are mainly applied for the protection of circuits
with inductive load installation.
For example: Fluorescent lamps, refrigerators, washing
machines and so forth.
DWP Residential Molded Case Circuit Breakers
Available in 175, 200 and 225 A, 3 pole version only, the DWP series circuit breakers have been developed
for the protection of electrical installations against overload and short circuit.
These protections are ensured by its thermal and magnetic triggers. Terminal boxes can be supplied as accessories for the DWP225 model, enabling direct cable connection up to 120 mm2.

RDW Residual Current Circuit Breakers
Residential current circuit breakers are devices used for the protection of people and installations as to direct
or indirect contacts. They protect against the effects of ground leakage, by detecting these leakages that can
occur in electrical installation and opening the circuit.
Regardless of the ground scheme, the use of these devices with
sensitivity equal to or less than 30 mA is recommended in
circuits:
a) situated in locations containing bath or shower.
b) current sockets located in areas outside the building.
c) current sockets that could have to supply outside equipment.
d) kitchens, dining areas, laundries, service areas, garages and
inside areas subjected to water or washing through normal use.
30 mA or 300 mA sensitivity
The sensitivity or rated residual operating current (ID n) is
the first factor to dictate if this product can be applied for
protection against indirect contacts and for complementary
protection against direct contacts, or if it can only be
appplied against indirect contacts.
The version with 30 mA sensitivity is considered to be of high
sensitivity and can be used both for protection against
indirect contacts as well as for complementary protection
against direct contacts, guaranteeing full user/person
protection.
The version with 300 mA sensitivity is considered to be of low
sensitivity and can be used only for the protection of
installations against indirect contacts or against fire risk
(according to installation standards), limiting the fault/ground
leakage currents to locations that process or store
inflammable materials, such as paper, straw, wood
fragments, plastics, and so forth.
Operating Curve
Operating Principle
The residual current circuit breaker continuously measures
the vectorial sum of the currents that go through circuit
conductors. If the electrical circuit is running smoothly, the
vetorial sum of the currents in its conductors is practically
null.
Should an insulation failure occur in a piece of equipment
supplied by this circuit, a ground fault current will appear.
When this occurs, the vectorial sum of the currents in the
conductors monitored is no longer null and the device
detects this current difference, opening the circuit.
In the same way, if somebody touches a live part of the
protected circuit, the current will circulate through the
person’s body, equally causing an unbalance in the vectorial
sum of the currents. This unbalance will also be detected as
if it was a ground fault current.

g Notes:
(1) The 2 pole version are normally used in phase/neutral or phase/phase systems.
(2) The 4 pole version can be used in any type of network.
(3) All phase conductors, including neutral, can be connected to RDW, however, the ground conductor must not be connected. The neutral conductor in the RDW outlet must remain insulated throughout the installation and must not be connected to the ground.
(4) If a 4 pole RDW is used as a 2 pole, the phase must pass through terminals
5-6 and the neutral through 7-8.

SIW Switch-disconnectors
The SIW switch-disconnectors have the same housing as the miniature circuit breakers for the 2, 3 and 4
pole versions. However, they are not provided with thermal and magnetic triggers, i.e. they do not have
trigger curves. Its function is only to disconnect electrical circuits with currents of up to 100 A in accordance
with IEC 60947-3 standard.
SPW Surge Suppressors
The surge suppressors (SPD) from the SPW series were developed to protect equipment and installations
against surges and over voltages coming from direct or indirect discharges in the electrical supply, more
commonly caused by lightning and/or operations in the electrical system.
Regardless of the type or origin, the discharges generate a sudden increase in supply voltage –
momentaneous surges and over voltages – which damage electro-electronic equipment and the installation
itself.
Protection Class
The Class I SPD are indicated for locations subject to high
intensity discharges, a typical characteristic of installations and
buildings directly supplied by overhead wires exposed to
atmospheric discharges. Installation of a Class I SPD is
recommended at the inlet point of a building’s electrical supply.
At locations where the electrical supply is not exposed to direct
atmospheric discharges, typical of internal residential and/or
building installations supplied by a built-in electrical supply, Class
II SPD are indicated. Its installation is recommended in the
distribution board.
Features
The SPW series are equipped with a status signaler, located on
the front of the device.
Although the SPDs operate many times, replacement of the
module is only necessary when the signaler is red.
The SPW series are Plug-in type. This concept enables the user
to replace the protection module without having to disconnect
the cables, as the base remains installed.
