The enclosure snaps onto the rail, and the RCD module then snaps into the enclosure. Module Width Adds minimal extra width to the housed RCD. A standard 4-pole RCD (72mm) inside this enclosure will have a total width of approximately 72mm + enclosure thickness. Key Safety Feature Completely covers the sides and front edges of the RCD module, preventing accidental contact with the metallic DIN rail clip or any exposed terminal areas from the side. The operator (test button, switch lever) remains accessible. Color Typically white or grey, to match standard consumer unit aesthetics. Standards Complies with relevant parts of IEC/EN 61439 (Low-voltage switchgear assemblies) regarding enclosures. Application Used in consumer units (distribution boards), panelboards, and enclosures where an extra layer of user safety and insulation is required for the RCD component.
