Circuit Breakers; Resetting The Button-Type Circuit Breaker; Replaceable Controller - Pro3X - LEGRAND Server Technology PRO3X User Manual

Circuit Breakers

PRO3X models rated over 20A (North American) or 16A (international) contain overcurrent protectors
for outlets, which are usually branch circuit breakers. These circuit breakers automatically trip
(disconnect power) when the current flowing through the circuit breaker exceeds its rating.
If a circuit breaker switches off power, the front panel display shows open. To find which circuit breaker
is open (trips), select Alerts or OCPs in the front panel display menu. When a circuit breaker trips, power
flow ceases to all outlets connected to it. You must manually reset the circuit breaker so that affected
outlets can resume normal operation.

Resetting the Button-Type Circuit Breaker

Your button-type circuit breakers may look slightly different from the images shown in this section, but
the reset procedure remains the same.
▶
To reset the button-type breakers:
1) Locate the breaker whose ON button is up, indicating that the breaker has tripped.
2) Examine your PRO3X and the connected equipment to remove or resolve the cause that results in
the overload or short circuit. This step is required, or you cannot proceed with the next step.
3) Press the ON button until it is completely down.
