The main function of the integrated fire-fighting linkage molded case circuit breaker is to be assembled to the side of the circuit breaker through modularization, which is convenient for user wiring management and use. The module is mainly divided into two units, one unit is the fire control power supply (shunt release), the other One is the fire-fighting feedback signal (auxiliary contact), let's talk about the fire-fighting control power first, the general power supply voltage is DC24V, and Ue is controlled by the C2 and C1 terminals respectively; the fire-fighting feedback signal module is mainly composed of F12, F11, F14 three Node combination, F11 is the common port, F12 and F14 are the opening and closing interfaces.

Precautions:

1. The fire control power supply is connected to the DC24V power supply, and it is forbidden to connect the AC230V or AC380V power supply;

2. F11, F12, F14 are connected to the fire feedback signal;

3. The two leads must be connected to any two phases 2, 4 and 6 of the single load side of the switch.
