ADDA SYSTEMS - AVALANCHE TRIP STEERING DIODE 5, 8 & 10

ADDA SYSTEMS - AVALANCHE TRIP STEERING DIODE 5, 8 & 10

Product News Monday, January 7, 2019: Mimic Components CC

These products are mostly used in electrical reticulation protection schemes for steering signals from multiple different sources to the main tripping relay that drops out the Circuit Breaker.

Avalanche rated diodes are used as the line inductance can generate large Back E.M.F. voltage when the circuit breaker interrupts the current. A normal diode is likely to be destroyed by the Back E.M.F. while an Avalanche diode will temporarily breakdown, pass the transient voltage and then return to normal operation, ready for the next tripping event.

Features

• 25 AMP DIODES

• 1600 VOLTS VRRM
