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.

The 3120 circuit breaker is also available as a switch-only version in

accordance with the IEC/EN 61058 (see data sheet switch 3120-F-..Q1).

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

push-in terminals

appliance inlet module
