2P Circuit Breaker Anti-Shock Protective Cover

Recently, I installed an EV charger at home. The prompt was to connect to the mains electricity. Since I was using the previous distribution box and it didn't have a DIN rail for the circuit breaker, I installed one. The circuit breaker clipped directly onto it, but the screw contacts were exposed, posing an electric shock risk during operation. So, I made a protective cover. After connecting the wires, the metal contacts are no longer exposed, and it works well.

If it's not an outdoor environment, using only a DIN rail with this protective cover is easier to install and much cheaper than using a circuit breaker box. The appearance of 2P circuit breakers below 63A is basically the same, so everyone can refer to and use this.
