Installing circuit breakers in a 28 Circuit Breaker Module on the DIN rail

Figure 3.7-2 Merlin Gerin 28 CB Module Installation Detail

Install the Merlin Gerin Circuit Breaker (CB) to the mounting DIN Rail on the 0M-2186 or 0M- 2579 circuit breaker module with the DIN rail lock positioned toward the main bus. The C60 style CBs should be installed from left to right on the main bus and the C120 style CBs should be installed from right to left on the main bus for the best use of the main bus positions.

Enable the CB’s DIN rail lock (the CB may still be moved laterally on the DIN rail for final positioning. Position the appropriate transition bus on the main bus and inserted in the opened CB connection area. Secure the transition bus to the main bus with the two M4x16 machine screws (SEMs) provided. Tighten the CB connection tightening screw on the transition bus.

Any combination of up to 28 Merlin Gerin circuit breakers may be installed on the 28 circuit breaker module. There are two different types of circuit breaker available: the C60 series circuit breaker and the C120 series circuit breakers. The two basic types of Merlin Gerin circuit breakers may be installed in combination as shown in the table below.
