NZM2(-4)-XKSA Terminal Cover

Terminal cover for NZM2 Molded Case Circuit Breakers and Switches

Models: -NA, -CNA (UL/CSA models)

Barrier Removal Instructions

The barrier, shown shaded in the diagrams, is held tightly into grooves on the top and bottom sides of the breaker or switch. It must be removed to mount the NZM2(-4)-XKSA terminal cover.

To remove the barrier:

From the back of the device, use thumb pressure to push the barrier.
Alternatively, use an appropriate tool to gently tap each side of the barrier to help slide it out.

Important Safety Information

Electric current! Danger to life!

Only skilled or instructed persons may carry out the following operations.

Caution! The removal or exchange of parts during mounting may become necessary. Refer to installation instructions for proper assembly and to maintain electrical clearances.

Use of Terminal Cover NZM2-XKSA on UL/CSA Models

The NZM2-XKSA terminal cover maintains electrical clearances and provides protection against accidental contact with live parts in the incoming and outgoing supply circuit terminations of the circuit breaker or switch.
The top and bottom portions of the terminal cover are mounted as shown in the preceding diagrams.
Use of the NZM2-XKSA terminal cover is always necessary with Type XKS screw terminations when making connections with bare bus or non-insulated crimp lugs, or when two wires per phase are connected.
Follow the guidelines illustrated for additional connection combinations.
