A12 4F 100

The A12 4F 100 is a 2-pole rocker-actuated Circuit Breaker for equipment with auxiliary contact. The rocker actuated version of the TA45 line of thermal CBE's can be used for various purposes. Basically it is a CBE for automatic interruption of overloads with facilities for regular manual ON/OFF switching operations under normal load conditions. It is capable of interrupting moderate short-circuit currents without the aid of backup protection. Another available version of this line utilizes an under-voltage release to protect persons against injuries caused by unexpected events like the automatic restarting of motors after a power failure. This release can be combined with the thermal release required for over-current protection. Protection against injuries is also provided by another CBE of this line, which prevents the starting of a machine should a protective cover be removed from dangerous parts of the machine.
