6.3 Removing the Trip Unit
To remove the trip unit from the circuit breaker, deflect the
spring clip underneath the trip unit with a screwdriver.
When unlocked, you will be able to pull the trip unit
straight out and, by doing so, will disengage the trip unit’s
printed circuit board connectors K1 & K2 from the circuit
breaker. This action should be firm, but not forced. (Fig.
6.3)
6.4 Removing the Trip Deck Mounting Plate
Using the Phillips screwdriver, remove the two top screws
that anchor the steel trip deck plate into the breaker
frame. Be careful not to damage the Trip Indicator
Assembly (and Over Current Trip Switch / Bell Alarm if
your breaker contains this option).
NOTE: Observe how the Trip Indicator Assembly (Fig.
6.4) tabs are located BEHIND the Trip Deck Mounting
Plate. Upon reassembly, the unit must be reattached in
an identical manner.
