A9V61440 SCHNEIDER ELECTRIC

The A9V61440 from Schneider Electric is a Vigi iC60 earth leakage add-on block designed to enhance electrical safety in various applications. This device is a 4-pole configuration, making it suitable for three-phase systems with a neutral conductor. It has a rated current of 40A, indicating the maximum current it can handle continuously without tripping. The sensitivity is set at 30mA, which is the threshold at which the device will detect an earth leakage fault and trip to interrupt the circuit. This level of sensitivity is crucial for preventing electrical shocks and minimizing the risk of fire. The SI type designation signifies that it is a super-immunized device, offering enhanced immunity to nuisance tripping caused by transient overvoltages or high-frequency currents. This feature ensures reliable operation in environments with potential electrical disturbances. By adding this earth leakage protection to a circuit breaker, it provides comprehensive protection against both overcurrents and earth leakage faults. This combination enhances the overall safety and reliability of the electrical installation. It is suitable for residential, commercial, and industrial applications where earth leakage protection is required.
