Tripping relays (cont.)

HIGH / LOW BURDEN CONFIGURATIONLow burden high speed tripping relays can be used when the initiating contact is placed close to the tripping relay.

However, in order to avoid unwanted trip relay operation due to pickup or transients, particularly if the relay operating coil is connected to extensive wiring, high burden high speed tripping relays can be used.High burden high speed tripping relays complies with ESI 48-4 international standard, as EB2 class relays.These EB2 class relays are suitable for use in high security circuit breaker tripping circuits, increasing their immunity to capacitance discharge currents.

For relays with rated voltage of 110 V, the relays will withstand, without operating a discharge into their operate circuits of a 10μF capacitor charged to 120% of the higher rated voltage for the relay, i.e 145.2 V.

For relays with rated voltage of 220 V, the relays will withstand, without operating a discharge into their operate circuits of a 10μF capacitor charged to 100% of the higher rated voltage for the relay, i.e 242 V.

Trip circuit supervision relay can also be used to supervise the trip circuit of the high speed tripping relays. If the circuit being supervised becomes an open circuit, the supervision relay will be de-energized and its output contacts will provide the related indications. In order to achieve this function, the relays should be connected as shown on the schemes :

Models Trip circuit supervision relay (single phase circuit breaker)

Trip circuit supervision relay (three phases circuit breaker)
