Tripping and Control Relays block MVAJ with (2NO & 5NC)

Original price was: ₹125.00.Current price is: ₹100.00.

Midos make MVAJ25 relay are suitable for use in high security circuit breaker tripping circuits. In particular they can be used in distributed tripping or control relay contact logic schemes, where the initiating contact may be remote from the relay. The relays have a high burden which is either cut off at operation or economised to a low figure, either instantaneously or after a time delay.

Features and technical specifications:

1. High speed operation
2. High and low burden alternatives
3. Low burden models suitable for ac and dc operation
4. Models surge proof against high capacitance discharge currents in the dc supply system, are available
5. Control relays immune to ac can be supplied

This Tripping and Control Relays block is easily insert in your schematic diagram and connect as you like way.

The high burden provides immunity to capacitance discharge currents, which can result at the inception of an earth
fault on battery wiring and immunity to the subsequent leakage current. The high burden also permits the use of supervision relays such as type MVAX where the wiring is at risk and provides reliable operation of series elements such as repeat relays type MCAA. For the latter purpose type MVAJ relays can be provided with a time delayed economising feature. These relays incorporate a break contact in series with the operate coil. Located on the main contact stack, it is arranged to break the coil circuit once the relay mechanism has completely operated. This reduces the relay burden to zero as soon as mechanical latching of the contacts has occurred. Types MVAJ 23 and 53 hand reset whilst the types MVAJ 24 and 54 have a second coil which, when energised, unlatches the relay resetting mechanism.
