Type B Leakage Protection Device

The Type B Universal Leakage Current Protection Relay is an advanced safety device engineered to detect and interrupt both alternating and direct residual currents, offering superior protection far beyond conventional Type A or AC devices. This capability is essential for modern electrical systems that increasingly incorporate DC components, such as photovoltaic installations, battery storage, and electric vehicle charging stations. By rapidly disconnecting the circuit upon detecting hazardous leakage, it effectively prevents electric shocks and significantly reduces the risk of electrical fires, ensuring the safety of personnel and critical equipment. This relay is compatible with AC230V/240V and AC400V/415V networks and supports rated currents of 25A, 40A, and 63A, with selectable residual operating currents of 30mA, 100mA, or 300mA to accommodate different sensitivity requirements. It features a rated impulse withstand voltage of 4kV and a short-circuit breaking capacity up to 630A…
