Thermal Circuit Breaker 3120-F...
Description
The 3120 circuit breaker/switch combination is an ON/OFF switch
with integral overcurrent protection (S-type TO CBE to EN/IEC
60934). The trip element is a bimetal. Type 3120 is ideally suited for
overload protection of motors, pumps, transformers and cables.
Product characteristics:
l rocker or push button actuation
l single pole and double pole versions
l reliable switching behaviour (positively trip-free)
l convenient snap-in mounting
l international approvals

Options and add-on modules:
l illumination
l water splash protection
l auxiliary contacts
l under voltage trip
l remote trip
Technical data
l magnetic trip (see thermal-magnetic circuit breakers)
l push-in terminals
For details please see Technical information
l appliance inlet module
