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). Designed for plug-in mounting with E-T-A sockets
17-P10-Si, 23-P10-Si, 63-P10-Si; or panel mounting using E-T-A clips.
Featuring an unprotected shunt tap terminal and optional auxiliary
contacts. Type 3900 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).
Process control systems, instrumentation, communications systems,
rail vehicles.
