| Type | Core Role | Structural Features | Operation and Safety |
|---|---|---|---|
| Plug-in (Front Panel) | It combines quick replacement with intuitive wiring and is compatible with standard cabinet wiring and mass assembly. | The insert base is mounted on the front of the panel, with the terminals facing outwards; wiring is completed on the front of the panel, making installation intuitive and requiring no special drilling. | Replacement can be performed by simply disconnecting the power and unplugging. Wiring and maintenance require space in front of the panel, and live parts are easily accessible, so caution is advised. |
| Plug-in (Rear Panel) | This achieves concealed wiring behind the panel and no wiring at the front for maintenance, improving cabinet neatness and operational safety. | The terminals are located at the rear of the panel; the base can be installed through the panel or led to the rear of the panel using extension terminals; holes must be drilled according to specifications. | Replacement requires no wire removal, and front-end operations are less likely to come into contact with live terminals, making it safer; however, space must be reserved behind the board for wiring and heat dissipation. |

A1: It allows for quick replacement and maintenance without disconnecting the main wires. This significantly shortens power outage times and minimizes maintenance downtime when a fault occurs.
A2: The base is pre-connected with the power and load wires during assembly. The main breaker body is simply plugged in or unplugged, which avoids the risk of incorrect or missing connections caused by repeated manual wiring.
A3: Front-panel plug-ins have exposed terminals facing outwards with wiring completed on the front, offering intuitive access. Rear-panel plug-ins have terminals located at the back, hiding the wiring behind the panel for a cleaner cabinet layout and enhanced safety.
A4: Yes. Because the wiring is concealed behind the panel, operators working at the front are prevented from accidentally touching live terminals, which greatly reduces the risk of electric shock.
A5: No, the dimensions vary depending on the model capacity. For example, the C1 dimension is 35mm for the M5-160/250 models and 45mm for the M5-400/630 models.
A6: Yes, both methods can be integrated into complete standardized designs, such as drawer cabinets and fixed cabinets. The base and cabinet body are pre-installed, and the main body is plug-and-play, which greatly improves assembly efficiency.
