Lock Out Relays

The Lock-Out Relay (LOR) plays an Important role in the most crucial utility applications.
In an emergency, the LOR Performance can make the difference between a routine outage and the destruction of very expensive equipment.

The LOR are high-speed control relays used as auxiliary relays in applications requiring many contacts up 24 at 25Amps up 50 at 20Amps.

When a failure occurs, the LOR intervenes, tripping the contacts and locking the system.
All the critical circuits will be isolated and will remain isolated until the malfunction is solved.
Its positive trip action ensures that all the contacts would perform as to requirements and its multi-contacts arrangements eliminate the need for several control relay contacts.

They are generally used in conjunction with differential relays to protect Circuit Breakers, Transformers, Buses and Rotating Machinery in various electrical systems.

Main Characteristics:
– Contacts design bounce-proof, ideal for high speed quick break design
– Tripping Time 10ms
– 5 Different Voltage Coils Available 24 – 48 – 110 – 125 – 220 Vdc
– External Rectifier for AC Voltage Applications
– Contacts can be silver (standard) or gold plated on request
