Reliable Auxiliary Signalling for Motor Protection Systems
Auxiliary contact blocks such as the Lovato SM1X1120 extend the functionality of motor protection circuit breakers by providing additional switching contacts for control and monitoring circuits. This allows operators and automation systems to receive clear status feedback from the protected motor circuit.
The SM1X1120 is particularly useful in control panels where breaker status needs to be linked to PLC inputs, alarm systems, indicator lamps or interlocking circuits. Its compact front-mounted format makes it easy to integrate into existing Lovato SM1 motor protection assemblies.
Typical Applications
- Motor protection breaker status signalling.
- Industrial control panels and automation systems.
- PLC input feedback circuits.
- Indicator lamp and alarm circuits.
- Machine building and OEM equipment.
- Motor control centres and electrical enclosures.
