Shunt-Trip Line Circuit Breaker; Single-Relay Dry Contact Kit (Dec 3+) - Kohler 20-2250 kW Operation

6.1.16 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 a customer-selected fault
such as an overspeed, auxiliary, or defined common
fault. Connection requires a shunt-trip wiring kit and a
dry contact kit. See Figure 6-28.
Typical Connection:
Auxiliary (26),
Defined Common Fault Line 1 (32),
Defined Common Fault Line 2 (32A), or
Overspeed (39)

6.1.17 Single-Relay Dry Contact Kit
The single-relay dry contact kit uses one set of contacts
to trigger customer-provided warning devices if a fault
condition occurs. Connect any controller fault output
connection from the TB1 terminal strip to the single-
relay kit. Use the single-relay dry contact kit as a
common fault relay for signaling any of the following
common fault conditions:
D
Emergency Stop (48)
D
Auxiliary (26)
D
Overspeed (39)
D
Low Oil Pressure (38)
D
High Engine Temperature (36)
Connect a maximum of three dry contact kits to a single
controller output. See Figure 6-29 and Figure 6-30.
