Type 3120-N

Type 3120-N

Description

The 3120-N…-…T1-… thermal circuit breaker/switch combination unites overcurrent protection and the function of an ON/OFF switch within a single component. The trip element is a thermal bimetal.
Type 3120-N…-…T1-… is ideally suited for overload protection of motors, pumps, transformers and cables. After tripping, it can reliably, easily and quickly be reset. The positively trip-free mechanism ensures reliable disconnection of the circuit even with the actuator blocked.

Type 3120-N is also available with thermal-magnetic trip: Typ 3120-N…-…M1-…

Your benefits:

  • Maximum equipment availability is ensured by overload protection perfectly matched with the loads (prevention of nuisance tripping) and quick resettability
  • Reduced mounting and wiring time
  • Space-saving design
  • Reduced disposition and storage costs
  • Increased overall reliability

Type 3120-N is also available as a switch in accordance IEC/EN 61058 (see data sheet switch only) and with X3120 Power Entry Module.
