and 3 NC auxiliary switches as standard.

configurations please contact for availability.
Mechanical operation counter
Easily fitted, this useful accessory may be specified
for use with either manual or motor charged
M-PACT circuit breakers. It is clearly visible through
the front panel, and the counter provides an
accurate record of the cumulative number of
complete breaker closing operations.
Key interlock facility
Castell key interlock version shown above
Ready-to-fit interlocking devices such as Castell,

breaker cannot be closed unless the dedicated key
has been inserted and secured within the lock.
