The Lock-Out Relay Plays an Important role in the Most Crucial Utility Applications.

In an Emergency, the Lock-Out Relay’s Perfomance can Spell the Difference Between a Routine Outage and the Destruction of very Expensive Equipments.

The Lock-Out Relays are high-speed control Relays used as auxiliary Relays in applications requiring many contacts (up 24).
They are generally used in conjunction with differential relays to protect Circuit Breakers , Transformers , Buses and Rotating Machinery in various electrical systems.

When a failure occurs , the Lock-Out Relay 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.

The COMELETRIC Lock-Out Relays Protects Your System and Your Personnel.

Characteristics
