Description
Typical applications
Ordering information Technical data
Single pole thermal-magnetic circuit breaker with tease-free, trip-free,
snap action mechanism and two button operation (M-type TM CBE
to EN 60934). Featuring a flange for panel mounting, and optional
auxiliary contacts and unprotected shunt tap terminal. Type 4000 offers
lower internal resistance values and is fitted as standard with auxiliary
contacts and an intermediate reset position in which all contacts are
isolated.
Approved to CBE standard EN 60934 (IEC 60934).
Control systems, instrumentation, medical equipment, machine tools,
robotics, communications systems.
