APL/UPL, 205/295 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 over-current protection, it’s simultaneously used
as an on-off switch.
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.
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 is available. Gold contacts are not
recommended for load current above 100 milliamps.
only in the event of an electrical trip of the circuit breaker.
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.
Auxiliary switch contacts actuate simultaneously with the
The contacts on our optional rS auxiliary switch will open

Relay Trip
This permits the overload sensing coil to be placed in a
circuit which is electrically isolated from the trip contacts.
The coil may be actuated by sensors monitoring pressure,
flow, temperature, speed, etc. Other typical applications
include crowbar, interlock and emergency/rapid shutdown
circuitry. Trip may be accomplished by voltage or current,
which must be removed immediately upon tripping.
Dual Coil
Dual coil protectors provide remote shut down option and
normal overcurrent protection in the confines of a single
breaker pole. This construction saves space by eliminating the
need for an additional pole for the voltage trip function.
Voltage Trip
Sometimes called “dump circuits” or “panic trip circuits,”
these units make it possible to open main power contacts
with lower power inputs from one or more sources. This
configuration is becoming increasingly more important for
sensitive circuitry and denser packaging in automation
systems. Available in series, shunt, relay or dual coil
configurations.
