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:
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:
