Chapter 5: Using the PX3TS

Overcurrent Protectors for Outlets
PX3TS 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 the circuit breaker switches off power, the front panel display shows:

CbE
, which means "circuit breaker error." See
Overcurrent
Protector Information
(on page 102).
At the same time, the internal beeper turns on. See
Beeper
(on page
138).
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.
Comparison: Fuses for the inlet transfer switch protect the inlet transfer
switch from overload. Overcurrent protectors for outlets, if available,
protect associated outlets from overload. The rating of a fuse for the
inlet transfer switch is higher than the rating of an overcurrent protector
for outlets. See
Fuses for the Inlet Transfer Switch
(on page 133).
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 PX3TS 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.
