3.1.12 Opening and Closing Circuit Breakers

MPH2 rack PDU feature circuit breakers to protect either branches or individual outlets, depending
on the model. Low-profile circuit breakers are used on all MPH2 rack PDU's with two or three branch
circuits. Standard-profile circuit breakers are used on MPH2 rack PDU's with six branch circuits or
have a 240VAC rating.
Both types of circuit breakers are flush-mount, rocker-style breakers. The circuit breakers are
designed to prevent accidental trips. To manually trip a circuit breaker to the Off position, insert a
flat-blade screwdriver or similar tool into the slot on the breaker as shown in Figure 29. To reset the
breaker, press the end nearest ON until it clicks into place.
