1. Rear-mounted wiring. The advantage of rear-mounted wiring is that when maintaining DC circuit breakers, only the upstream power supply needs to be disconnected, without rewiring. This type of structure is relatively special and comes with a dedicated mounting plate and screws. Installation must be strictly in accordance with the manufacturer's requirements to avoid affecting the normal operation of the circuit breaker.
2. Plug-in wiring. The advantage of plug-in wiring is that when the circuit breaker needs to be replaced, simply pull out the old circuit breaker and replace it with the new one. Operation is faster and more convenient than front-mounted and rear-mounted wiring. When using this method, ensure the plug is securely tightened to reduce contact resistance and improve safety and reliability.
3. Drawer-type wiring. For products such as DC circuit breakers, the drawer is moved in and out by rotating a lever clockwise or counterclockwise. A plug-in structure should be used on both the main and secondary circuits. This allows for dual-purpose use, saving operating costs and offering significant advantages in terms of ease of operation and maintenance.
