Technical Specs
- Current Rating: 40A
- Voltage Rating: 230V up to 400V
- Type: Double Pole perfect for protecting outdoor equipment e.g. EV charge points EVSE
- Mounting: DIN Rail
- Application: EV Charger Consumer Unit
This type of 40A double-pole MCB is a solid choice alongside an EVSE setup because it provides clean, reliable overcurrent protection with full isolation of both live and neutral. In EV charging applications, especially when you’re dealing with adapters or auxiliary power outputs, having a device that can safely disconnect the entire circuit in one action is a big plus for both safety and maintenance. The C-curve characteristic also makes it well-suited to handle the brief inrush currents you can get when equipment powers up, without nuisance tripping. When paired correctly with appropriate upstream protection (like an RCD where required), it adds a dependable layer of control and protection to an EVSE installation, keeping the supply stable while safeguarding cables and connected equipment.
Compatibility & Safety Notes
This MCB breaker is designed for use with EV charging circuits and should only be installed by qualified personnel. Ensure that the installation complies with local electrical regulations. Regular maintenance checks are recommended to ensure optimal performance and safety.
