Circuit Breakers
PX 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:
 A PX3
phase I
model's LCD display shows
CbE
, which means
"circuit breaker error." See
Overcurrent Protector Information
(on
page 561).
 A PX3
phase II
model's LCD display shows
open
. To find which
circuit breaker is open (trips), select Alerts or OCPs in the Main
Menu. See
Operating the Dot-Matrix LCD Display
(on page 62).
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.
Depending on the model you purchased, the circuit breaker may use a
button- or handle-reset mechanism.
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 PX 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.
