MVAJ205  High-speed tripping and control relays

The MVAJ range consists of highly reliable hinged armature relays designed to directly operate circuit

breaker trip coils. Built to very high specifications, the MVAJ range provides an extremely flexible and reliable link between the protective relays and the circuit breakers.

Numerous features and configurations for multiple tripping schemes

Equipped with a wide range of features and configurations, the MVAJ range can be applied to all types of

tripping schemes. Operating at high speed with very little contact bounce, this range is available in hand, electrical and self-reset models.

An external link connection enables selection of high or low burdens and a delayed cut-off is available for

high-burden applications. The MVAJ range is also equipped with AC or DC operating functions for low burden configurations and it ensures immunity to any wiring capacitance discharge.

Protective relays are precise measuring devices, the contacts of which should not be expected to switch large electrical loads. In some
cases, the protective relay may trip a circuit breaker directly, or according to the coil rating and the number of circuits to be energised,
may do so using a MVAJ tripping relay. The MVAJ relay interfaces the protection relay with the circuit breaker to provide the higher
contact capacity, additional contacts for tripping multiple circuit breakers, control functions, signalling and interlocking.
