Abstract: A pluggable module includes a power control unit, an interface unit, a monitoring unit, and a signal linkage unit. The power control unit is connected to the interface unit, and the pluggable module can be inserted into an external device by using the interface unit. One end of a pull ring is rotatably connected to a bracket, and the other end can trigger a signal switch. When the pull ring is in an ON state, the signal switch is triggered to send a first switch signal, or when the pull ring is in an OFF state, the signal switch sends a second switch signal. The monitoring unit is configured to control, upon receiving the first switch signal, the power control unit to be powered on, or control, upon receiving the second switch signal, the power control unit to be powered off.

Abstract: A reverse power connection preventing circuit includes a diode and an actuation unit that are connected in series between a positive input terminal and a negative input terminal of a circuit breaker. A positive electrode of the diode points to the negative input terminal of the circuit breaker, and a negative electrode of the diode points to the positive input terminal of the circuit breaker. When a power supply is forward connected to the circuit breaker, the diode is cut off, there is no current on the actuation unit, and the reverse power connection preventing circuit is in a power-off state. When the power supply is reversely connected to the circuit breaker, the diode conducts, and the actuation unit is configured to prevent closing of the circuit breaker, and/or the actuation unit is configured to perform an alarm prompt, to perform an early warning.

Abstract: The power distribution component is configured to connect to a power distribution box in a pluggable manner. A main body is provided with a first power terminal, a signal terminal, and a second power terminal that are arranged along a first direction. The first power terminal is configured to electrically connect to a first power busbar of the power distribution box, the signal terminal is configured to electrically connect to a signal busbar of the power distribution box, and the second power terminal is configured to electrically connect to a second power busbar of the power distribution box. Polarities of the first power terminal and the second power terminal are opposite. An end, facing away from the main body, of the mistake proofing structure is provided with an abutting surface, configured to abut against the signal busbar when the power distribution component is reversely inserted into the power distribution box.
