Thermal-Magnetic Circuit Breakers 3500/4000
Description
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).
Typical applications
Control systems, instrumentation, medical equipment, machine tools,
robotics, communications systems.

Magnetic tripping currents are increased by 20% on DC supplies.
Magnetic tripping currents are decreased by 20% on AC 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 – Technical information.
