Thermal-Magnetic Circuit Breaker 3120-...-M1-..
Description
Single or two pole rocker switch/thermal-magnetic circuit breaker
with trip-free mechanism (S-type TM CBE to EN 60934). The addition
of a magnetic tripping module to the type 3120 range described
in catalogue section Thermal Overcurrent Circuit Breakers extends
the choices available to include single pole with thermal-magnetic
protection; double pole switching with thermal-magnetic protection
on one pole, thermal protection on the other; double pole switching
with thermal-magnetic protection on one pole only. All are offered
with rocker switch or push button control - two buttons for ON/OFF
or one button press-to-reset only, in designs to suit one of three
different panel cut-out sizes. Illumination is optional.
Approved to CBE standard EN 60934 (IEC 60934).
Meets the requirements regarding fire resistance of EN 60335-1 :
2007-02 Safety of household and similar electrical appliances.

Magnetic tripping currents are increased by 25% 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
