Type A selective Earth Leakage add-on Block designed to offer protection against alternating and pulsating unidirectional leakage currents. Due to its selectivity, it ensures gradual and coordinated tripping with other protective devices, avoiding unnecessary power interruptions.
With a sensitivity of 1000 mA, this earth leakage add-on block is particularly suitable for high leakage protection in industrial plants, protecting against overloads and reducing the risk of electrical fires. The maximum peak current of 5 kA ensures resistance even under critical fault conditions.
Designed to operate in demanding environmental conditions, the device has an operating life of 10,000 electrical cycles, ensuring a long service life. The IP2X degree of protection makes it safe against accidental contact with live parts.
The differential block is compatible with rigid and flexible conductors up to 25 sq. mm and offers an insulation voltage of 500V with an impulse withstand of up to 4kV, ensuring maximum reliability in any context.
Due to its high performance, the differential block is perfect for industrial environments, large electrical systems, distribution boards and commercial sectors, where effective protection without unexpected interruptions is required.
