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 a power
disconnect.
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.
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.
Remote Indication, AP1-1R
AP series trip circuit protectors are available with electrically
isolated contacts which are rated at 1/2 ampere, 120 volts AC
or 50 volts DC. These contacts provide SPDT switching action
which can be used to indicate “power-on” and “power-off”
conditions or to actuate lights, alarms or timing devices.
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 or relay configurations.
