Circuit Breaker Accessory

Internal accessory

Shunt release

Connection diagram,see Fig 1 an Fig 2.
Rated voltage of control power suppy: AC 50/60Hz, 230V, 400V; DC24v, circuit breaker can operate reliably under 85% to 110% of the rated control power supply voltage.

1

Note:Explanation of the symbol K in Fig 2

K: Shunt release
The micro switch connected in series with the internal coil is a normally closed contact. When the circuit breaker is opened, the contact opens itself and closes when it is closed.

Under-voltage release

When the voltage is below 35% of the rated control power voltage, this release can prevent circuit breaker against closing. Wiring diagram, see Fig 3.

When the voltage decrease to the range of 70% to 35% of rated control power voltage, the under-voltage release would trip.

When the voltage is in the range of 85% to 110% of the rated control power voltage, this release can ensure the circuit closing reliably.

Notice: The circuit breaker with under-voltage release could trip and close, only supplied the circuit breaker with rated voltage.
