Trip Actuator Disassembly

The existing Westinghouse

trip actuator must be

converted to the new MicroVersaTrip

flux shifter

assembly. The following steps will detail how to
disassemble the trip actuator and which components must
be saved. The actual assembly of the new
MicroVersaTrip

flux shifter is detailed later in this

manual.

Step 1.

Separate the bottom cover of the Westinghouse

trip

actuator by removing the tape wrapping at the joint of the
two housings (Fig. 6). Discard the bottom housing cover.

Step 2.

Remove the 7/16” self-locking hex nut from the bottom of
the actuator shaft. Slide the actuator shaft out of the
assembly (Fig. 7). Discard the actuator shaft and hardware.

Step 3.

Separate the upper housing assembly from the actuator
frame by removing the two (2) hex nuts which are located
on top of the actuator frame (Fig. 8). Discard the upper
housing and hardware. Save, clean, and lubricate the
actuator frame and reset mechanism.
