ELCB Circuit Breaker — AC 2P 63A 30mA Key benefits Protects people and equipment: residual-current protection (30 mA) combined with two-pole switching prevents electric shock from direct and indirect contact and detects insulation faults that can lead to fire. Simplifies system safety for EV and PV projects: sized and rated for common charging pile and inverter circuits so you can standardize protection across installations. Reliable, long-term operation: engineered with a robust design and modern protection technology to maintain system uptime and reduce fault-related downtime. What it does (function and performance) Residual current device with 30 mA sensitivity to quickly interrupt leakage currents and reduce risk of electric shock. 2-pole (2P) AC configuration rated at 63 A for protecting single-phase AC circuits used in charging and power-conversion equipment. Provides both indirect and direct contact protection plus detection of insulation faults that could cause fires. Compatibility and application scope Direct fit for AC 2P 63A 30mA circuits used in: Charging piles and EV charging stations Photovoltaic (PV) installations and associated inverters Systems with frequency converters and motor drives Equally suitable for residential buildings, tertiary (commercial) facilities, and industrial environments where reliable residual-current protection is required. Why choose this ELCB Designed specifically for charging infrastructure and power-conversion equipment to address common leakage and insulation-fault risks in those systems. Compact 2-pole arrangement and 63 A rating align with standard circuit requirements, simplifying selection and installation. Robust construction and tested protection behavior help reduce nuisance trips while maintaining safety. Typical use scenarios EV charging station: installed at the feeder of a charging pile to interrupt leakage currents and protect users during plug-in and charging operations. PV inverter protection: placed upstream of a PV inverter to detect insulation breakdowns or ground faults and prevent fire risks. Industrial drive panel: integrated into the distribution board feeding frequency converters to protect personnel and equipment from residual current faults.
