Description
An extremely versatile range of rocker switch/thermal circuit breakers
(S-type TO CBE to EN 60934 with trip free mechanism) offering the choice
of single pole, double pole with single pole protection, and double pole
with protection on both poles. Designed for snap-in panel mounting with
versions available for three different panel cut-out sizes. Illumination is
optional and there is a range of colours and markings for the rocker.
Add on modules:
Under voltage release coil (for double pole versions only).
Magnetic trip coil for short circuit protection.
Magnetic trip coil for remote relay trip.
Auxiliary contacts for status signalling.
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.
3120-F3...F5
