Description

Will be replace

The 3120-F 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-F is ideally suited for overload protection of motors, pumps, transformers and cables.

Product characteristics:

rocker or push button actuation
single pole and double pole versions
reliable switching behaviour (positively trip-free)
convenient snap-in mounting
international approvals

Options and add-on modules:

illumination
water splash protection
auxiliary contacts
under voltage trip
remote trip
magnetic trip (see thermal-magnetic circuit breakers)
push-in terminals
appliance inlet module

This product is also available as switch only (more information see data sheet).

Important information:
By the end of this year, the new design version 3120-N will entirely replace the predecessor 3120-F. The last order date for series 3120-F is the 31 December 2020 (last delivery date: 30 June 2021).
