Application & Functions vajh13: The VAJ variety comprises very reliable hinged armature relays designed to straight operate circuit breaker trip coils. Constructed to very high specifications, the VAJ range provides an extremely flexible and reliable link between the particular protective relays and the circuit breakers.
Functions of GE VAJH13 Alstom auxiliary relay:-
High-speed operation
High level of mechanical stability
Optimistic action without chatter
Compact
GE vajh13 Auxiliary Relay Uses
High-speed tripping duties where a number of simultaneous switching procedures are usually required.
Common Description on the auxiliary relay:-
- A fast operating multi-contact attracted armature relay with a high level of mechanical stability.
- Type VAJH 13 relay has hands reset contacts and is available in two versions- high burden and low burden.
- Type VAJh 13 has personal reset contacts and is a low burden relay.
- Kind VAJH 13 high burden relay with hand reset contact is recommended
- where supervision of the vacation relay coil is desired.
The working current for all versions is in excess of 0. 025 amp and the relays are ideal for the procedure on D. C supplies fitted with a negative potential biasing device.
High burden electrical relays are recommended in high-security circuit breaker tripping circuits. The high burden provides immunity against operation due to capacitance discharge currents. Reduced burden relays are generally used when a number of simultaneous functions are to be initiated by an individual protective relay having insufficient contacts of its own and where series linked operation indicators are not used.
