CONFIGURATIONS
Series Trip
The most popular configuration for magnetic
protectors is the series trip where the sensing coil
and contacts are in series with the load being
protected. The handle position conveniently
indicates circuit status. In addition to providing
conventional overcurrent protection, it’s
simultaneously used as an on-off switch.
Shunt Trip
The shunt trip is designed for controlling two
separate loads with one assembly. The control is
established by providing overload protection for the
critical load. When the current through this load
becomes excessive and reaches the trip point, the
protector will open and remove power from both
loads simultaneously. The total current rating of both
loads must not exceed the maximum contact rating.
Dual Coil
By combining two electrically independent coils on
a common magnetic circuit, it is possible to provide
contact opening when either an over-current or trip
voltage is applied to the respective coils. One coil
will be a current trip coil with standard
specifications. The second, or dual coil, can be used
to provide a control function permitting contact
opening from a remote interlock or other transducer
functions. Standard coils are 6, 12, 24, 48, 120 and
240 volts. Tripping is instantaneous and must be
removed (usually self-interrupting) after trip.
Auxiliary Switch (Applies to Series Trip Only)
This is furnished as an integral part of a series pole
in single or multi-pole assemblies. Isolated
electrically from the protector’s circuit, the switch
works in unison with the power contacts and
provides indication at a remote location of the
protector’s on-off status.
with the main breaker contacts, and will open
regardless of whether the breaker contacts are
opened manually or electrically. For auxiliary switch
ratings below 6Vac or 5Vdc, an auxiliary switch with
gold contacts, designated as REG is available. Gold
contacts are not recommended for load current
above 100 milliamps.
