Type: 3120-F
Description
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 (date of last order acceptance).
