High Performance Thermal-Magnetic Circuit Breaker 437-...
Description
Single pole high performance thermal-magnetic circuit breaker with
tease-free, trip-free, snap action mechanism and toggle actuation
(S-type TM CBE to EN 60934). Options include auxiliary contacts, a
moulded flame retardant enclosure for added environmental protection,
and remote operation - disconnection only, or disconnection and
re-connection. Also available in an IP65 housing (see type E-1032).
Typical applications
Battery and cable protection for all types of vehicles (including rail
vehicles and boats), battery powered systems.
