Indication LEDs

The TS trip system and circuit breaker status are indicated locally by a combination of LEDs:

  • The status bar

  • The service LED

  • The ready LED

  • The trip cause and alarm LEDs

The indication given by the LEDs depends on how the TS trip system is supplied by:

  • The internal current transformers (CT)

  • The internal battery

Indication LEDs with TS Trip System Supplied by Current Transformers

The TS trip system is supplied by the internal current transformers (CT) when the EasyPact MVS circuit breaker is closed. If the load current is more than 0.2 In, the local indication is provided as indicated in following table.

Trip Indication LEDs After a Trip

When the circuit breaker is tripped, the trip cause is indicated by the trip cause LEDs and the status bar. The trip cause LEDs and the status bar are powered by the internal battery.

When powered by the internal battery, the trip cause and alarm LEDs are turned off after 2 hours.

After 2 hours, use the button to switch on the indication LEDs.
