CONFIGURATIONS

The most popular configuration for magnetic protectors is the
series trip where the sensing coil and the contacts are in
series with the load being protected. In addition to providing
conventional overcurrent protection, it is simultaneously used
as an on-off switch.

Single Pole
Two Pole
( 1 pole shunt)
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 current rating of both loads must
not exceed the maximum contact rating.

Two Pole
(1 pole relay)
This permits the overload sensing coil to be placed in a circuit
which is electrically isolated from the 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 after trip.
