COFRET-VE12-4P-40A, Protection box
COFRET boxes are designed to offer electrical protection in compliance with the ITC-BT-52 standard for infrastructures designed to charge electric vehicles. The devices have a Type A RCCB for direct or indirect exposure protection, and a C-curve circuit breaker to protect the recharging units in the event of overloads or short-circuits. If the installation does not have overvoltage protection, a model is available that includes both permanent and transient surge protection.
The COFRET box is absolutely essential when installing any single-phase electric vehicle charging point.
