87CB TM 3300 3400
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.

Magnetic tripping currents are increased by 20% on DC supplies.
The time/current characteristic curve depends on the ambient temperature
prevailing. In order to eliminate nuisance tripping, please multiply the circuit
breaker current ratings by the derating factor shown below. See also section 9
