Features: Make of ABS and offers excellent insulation. Works normally at temperatures from -40 to 55℃, resistant to high/low temperatures. Provide electric leakage Protections, overloads Protections and short circuit Protections. Breaking capacity up to 6kA. Compacts size, small space occupation. It can not only detect normal current, but also high frequency and small fault current (type A), thus reducing the impacts of equipment damage and other unexpected event. Suitable for wall box/charging stations/photovoltaic systems/inverter systems. Specifications: Materials: Plastic Size: about 8.20x4.9x7.2cm/3.23x1.93x2.83inch Current: 63A Polarity: 4P Leakage Action Current: 30mA Voltages: AC400 Package Includes: 1Pc Leakage Circuit Breaker note: Please allow 1-2cm errors due to manual measurement, make sure that you do not mind before you order.
