Auxiliary contact (TMC 7/8 AUX)

5.4

Shunt trip (TMC...SHNT)

The TMC 7/8 AUX is an auxiliary contact with one normally

open and one normally closed contact. The status of the

contacts are switched when the breaker on/off state

changes.

The TMC 7/8...SHNT provides an electrically operated

remote trip for the circuit breaker.

After the TMC 7/8 AUX module is attached to the

TMC 8... circuit breaker, terminals 11 and 14 are

connected when the circuit breaker is in the “on”

condition. Terminals 11 and 12 are connected

when the circuit breaker is in the “off” condition.

Accessory installation

Installation is the same for all types of

accessories.

1. Remove the end pieces (1) from the TMC 8... by sliding

it up and away from the center section (2) of the circuit

breaker.

5.3

Alarm contact (TMC 7/8 ALARM)

The TMC 7/8 ALARM provides an additional contact which

can be connected to a bell, light or other alarm. If the

TMC 8... trips, the alarm contact switches power to the load.
