Auxiliary contacts are designed for direct cooperation with overcurrent circuit breakers. The PS ETIMAT 10 auxiliary contact works with the ETMAT 10 version of the circuit breaker. During the installation of the auxiliary contacts, the circuit breakers must be turned OFF. The external dimensions are identical to those of the circuit breaker. Auxiliary contacts do not have their own surprise. Auxiliary contacts are used for remote signaling of the circuit breaker status (on, off) or for controlling individual current circuits. The width of the PS ETIMAT 10 auxiliary contact module is 9mm. Auxiliary contact PS ETIMAT 10 Can also be used for SV switch disconnectors 16A - 40A
