Molded-Case Circuit Breakers
MicroVersaTrip Plus™ Trip Unit in TJH1S, TJH4S,
Introduction
This publication contains information on mounting dimensions, lugs, internal and external accessories, and trip unit and rating plug selection for K Frame molded­case circuit breakers. It also describes the installation of neutral current sensors for ground-fault protection.
Lug Selection
Circuit breakers are provided without lugs. The available lugs are listed in Table 1.
Wire ranges are as follows:
• TCAL43: (1) 6–600 MCM or (2) 2/0–250 MCM
• TCOL43: (1) 6–600 MCM or (2) 2/0–250 MCM
• TCAL63: (2) 4/0–350 MCM Cu or (2) 300–500 MCM Al
• TCOL63: (2) 250–350 MCM

Test Kit, Cat. No. TVRMS2
The portable, battery-powered test kit provides for MicroVersaTrip Plus or PM unit self-tests and functional trip/no-trip tests. It also provides for defeat of the ground-fault function and can be used in conjunction with high-current test equipment. Interface is via a plug on the front of the trip unit and tests can be conducted with the breaker in service. The kit can also be powered by a 120 Vac source.
Application Information
For information on derating, time-current curves, inspec­tion, and testing, refer to GE publication GET-2779.
2. Lift off the lower half of the circuit breaker cover.
3. Attach the leads of the current sensor to the termi-
nations shown in the illustration. The vertical sur­faces of the terminals closest to the trip unit are labeled BLACK and WHITE on the left and right sides of the breaker, respectively. Maintain the proper polarity by connecting the black wire to the black connector and the white wire to the white connector. Use #14 AWG (minimum) twisted-pair insulated conductors.
Neutral Current Sensor Connection
A neutral current sensor must be used for ground-fault protection on all single-phase, three-wire systems and three-phase, four-wire systems.
1. Remove the four screws that hold the lower half of
the circuit breaker cover in place.

4. File break-out locations in the bottom cover with a
circular file. Route the ground-fault leads out the bottom cover, being careful not to pinch the leads.
5. Replace the breaker cover, then replace the lug
cover, attaching both with the fasteners removed in step 1. Tighten the screws to 14–20 in-lb.
These instructions do not cover all details or variations in equipment nor do they provide for every possible contingency that may be met in connection with installation, operation, or maintenance. Should further information be desired or should particular problems arise that are not covered sufficiently for the purchaser’s purposes, the matter should be referred to the GE Company.
