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 (please see data sheet circuit breaker p. 19 ff).
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).
