It provides earth-leakage protection for a single-phase circuit at 230 V AC, 50/60 Hz, with a rated current of 40 A and a 30 mA trip sensitivity. The 30 mA sensitivity covers standard personnel protection against direct contact, while the Type A-SI (Super Immunised) classification means it resists nuisance tripping from high-frequency leakage or pulsed DC waveforms — common on variable-speed drives, UPS systems, or LED lighting circuits that generate smooth DC fault currents a standard Type A might miss.
Tunnel terminals accept 1 to 16 mm² rigid or 1 to 10 mm² flexible cable, tightened to 2 N·m. At 74 mm deep and 95 mm tall, it fits standard modular enclosures with IP40 protection in the enclosure (IP20 on the terminals). The white housing matches the Acti9 family aesthetic for panel builders who care about visual consistency.
