MVAJ205 High-speed tripping and control relays

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 can trip a circuit- breaker directly, or according to the coil rating and the number of circuits to be energised.
The MVAJ relay interfaces with the protection to provide: higher contact capacity, additional contacts for tripping multiple circuit-breakers, control functions, signalling and interlocking.
The MVAJ range comprises very reliable hinged armature relays designed to directly operate circuit-breaker trip coils. Built to very high specifications, the MVAJ range provides a highly flexible and reliable link between the protective relays and the circuit-breakers.
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
