Shunt-Trip Line Circuit Breaker - Kohler APM402 Operation

6.1.17 Shunt-Trip Line Circuit Breaker

A shunt-trip line circuit breaker provides a 12- or 24-DC volt solenoid within the line circuit breaker case that can energize the
trip mechanism. This feature allows the circuit breaker to be tripped by the common fault (32A). Connection requires a shunt-
trip wiring kit and a dry contact kit. See Figure 85 and Figure 86.
The optional common fault relay shown in Figure 86 as DCB1 has contacts rated at 10 amps at 28 VDC or 120 VAC and is used
to trigger the shunt-trip line circuit breaker kit.
