High Performance Thermal-Magnetic Circuit Breakers 410/520/530-...
Description
Single, double and three pole high performance thermal-magnetic
circuit breakers with tease-free, trip-free, snap action mechanism and
toggle actuation (S-type TM CBE to EN 60 934; also to EN 60 947).
Designed for rail, panel or surface mounting. Available with a choice
of characteristic curves and optional auxiliary contacts.
Typical applications
Motors, generators, transformers, thyristors and silicon rectifiers.
