Thermal-Magnetic Circuit Breakers 3300/3400
Description
Single pole thermal-magnetic circuit breakers with tease-free, trip-free,
press-to-reset, snap action mechanism (R-type TM CBE to EN 60934;
M-type with manual release (-H). Available with fast acting and standard
magnetic tripping characteristics - types 3300 and 3400 - both with
threadneck panel mounting. Options include auxiliary contacts, a
separate shunt tap terminal (-A3), and pull-to-trip manual release (-H).
Approved to CBE standard EN 60934 (IEC 60934).
Typical applications
Control systems, instrumentation, medical equipment, machine tools,
robotics.
