Part identity and core ratings
It switches loads up to 20 A under AC-7A (resistive) and AC-7B (motor) duty categories, with a maximum power of 3.6 kW at 250 V AC. Control is via a 230 V AC 50 Hz maintained signal, drawing an inrush of 11 VA. The contact composition is 1 N.O.
The 18 mm width (1 module) and 60 mm depth keep panel fill factor tight. IP20 body protection suits dry indoor cabinets; IP40 on the modular enclosure face provides splash resistance during commissioning. Terminals accept up to 4 mm² rigid or 2.5 mm² flexible cable (ferrule optional). Wire strip length is 10 mm; tightening torque is 1 N.m. Two tunnel-type terminals per pole allow daisy-chaining without a separate distribution block.
Durability and environmental tolerance
Rated for 5,000,000 electrical and 5,000,000 mechanical operations — this is a high-cycle device suited to frequent switching in lighting or HVAC control circuits. Switching frequency is 6 operations per minute.
Compliance documentation covers EN 60669-2-1 (switches for household and similar fixed electrical installations). The IP ratings and tropicalisation class are factory-tested per IEC 60529 and IEC 60068-1 respectively.
