Interrupteur différentiel RCCB 2P 40A 30mA Type AC à réarmement automatique AC230V avec protection contre les fuites de courant, montage sur rail DIN 35mm

【Automatic resetting】This rccb differential switch after unexpected triggering of an MCB/RCCB, eliminating the need for manual reset. This reduces maintenance costs, helps resolve failures quickly, and improves efficiency. 【3 built-in resettings】If a fault persists and causes continuous triggering for 15 minutes, the auxiliary contacts issue a warning. Automatic reset interval: 10-60-300 s; Reset time: no manual triggering or reset within 15 minutes of successful reset. 【High Sensitivity】The automatic reset rccb differential switch can accurately detect low leakage currents and cut off the faulty power in time to ensure a quick power cut off in case of leakage fault, to protect the safety of people and equipment. 【Manual/Automatic Selection Switch】It is equipped with a manual/automatic selection switch with mechanical and electronic double locking functions for increased safety. LED indicators indicate working status and prevent malfunctions, ensuring stable and reliable operation. 【Wide Application】RCCB differential switch is suitable for electrical grid terminal lines, unstaffed mobile phone base stations, elevators, air conditioners, homes, factories and charging stations for new energy vehicles in places with high electrical safety requirements.
