Models Available

• Trip relays

Trip relays possess a standard hand-reset flag and operate within 10 ms.

Table 1 shows  the trip relay versions available

• Control relays

Control relay variants of each trip relay are available. These relays operate within

approximately 15 ms

All relays configured for high burden applications are suitable for DC operation only

Applications

Self-reset relays reset when the initiating signal is removed,

making them suitable for use as trip relays in auto-reclose

schemes and also for general flagging purposes. Hand-reset relays

require manual resetting, making them effective lockout relays

which are commonly used to trip circuit-breakers associated with

transformers. Electrical-reset relays require a voltage to be

applied to the unit to reset the contacts. These relays may be

used in auto-reclose schemes, or where remote resetting of the

relay is required.

Trip Relay

With the exception of the MVAJ 102 time delayed self-reset

relays, all trip relays are suitable for either low burden or high

burden applications.
