Figure 6 TMC 7/8 AUX schematic
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.
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.

After the TMC 7/8 ALARM module is attached to
the TMC 8... circuit breaker:
– Terminals 91 and 92 are connected when the
circuit breaker is in the “on” condition.
– Terminals 91 and 94 are connected when the
circuit breaker is tripped electronically.
– Terminals 91 and 92 are connected when the
circuit breaker is tripped manually.
– At the same time, terminals 91 and 94 do not
make contact.
