2 modules 230 Vac from 30 mA to 5 A, B type earth leakage relay with alarm Type B earth leakage relays are essential components in industrial electrical installations or for EVSE applications. They offer advanced protection against leakage currents, ensuring the safety of people and electrical equipment. Unlike type A and AC earth leakage relays, type B earth leakage relays are able to detect residual currents with both DC and AC components. This relay is used in conjunction with a trip protection device (automatic power cut-off) and provides protection against indirect contact. The aim is therefore to limit earth leakage currents to ensure the safety of people and property. This makes it a versatile, high-performance solution, suitable for a wide range of applications (vehicle charging points, heating systems, variable speed control, etc.). This model has an additional alarm relay, which warns of a fault, throw a No NC contact for BMS or pilot light. Remote information This model has an additional alarm relay (NO, NC). It provides remote access (via an automaton or BMS) to inform about an electrical circuit fault. Using this additional alarm relay connected to a pilot light, you can visualise a fault directly on the door of an electrical cabinet. Increased sensitivity The type B earth leakage relay is highly sensitive for detecting even small leakage currents. Its detection range of 30 mA to 3 A (depending on the differential toroid) means it can react quickly in the event of an earth leak. This sensitivity guarantees optimum protection, even in situations where residual currents are low.
