LOR – LOCK OUT RELAYS FUNCTION 86

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

In an Emergency, the LOR Perfomance can Spell the Difference Between a Routine Outage and the Destruction of very Expensive Equipments.

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

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 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.

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

Main Characteristics:

 * Contact system with self-cleaning action on both sides of contact, suitable for being used in highly aggressive environments, with presence of high percentage of saline dust and corrosive agents

 * Contacts design bounce-proof , this makes it ideal for high speed quick break design like the Lockout Relays.

 * Tripping Time 10ms.

 * 5 Different Voltage Coils Available 24 – 48 – 110 – 125 – 220 Vdc

 * External Rectifier for AC Voltage Applications

 * High mechanical strength, shaft and main structure in zinc plated steel, suitable for tropical climates.

 * The contacts are thickly silver (standard) or gold plated on request.

LOCKOUT RELAY

WITH TRIP COIL MONITORING SYSTEM

Model : LR109

Thanks to the supervision system , there is and instantaneous signalling of the malfunctioning of the relay releasing Coil, by means of

Visual LOCAL indication (GREEN LED=FUNCTIONING COIL /YELLOW LED= COIL INTERRUPTED) and REMOTE thanks to a change over contact that can be connected SCADA.

Also present is the Visual LOCAL FAULT indication via RED LED , in this case it is unless to arm the relay as long as the indication is present.

Available Voltages : 24V – 48V – 110V – 125V – 220Vdc

LOCKOUT RELAY

WITH MANUAL PUSH BUTTON RELEASE

Model : LR103

The manual release is mean thank to a push button located below the Handle of the LOR , the action is directly on a Mechanical lacting mechanisme of the LOR.

This is Used as Emergency or Test.

This permit to latch the relay also in case of burning of the coil.
