DOEPKE RSS 016-300 differentiaalivirtavalvonta 16A 300mA tyyppi A 2-napainen DIN-kisko 9981072

Residual current monitor with a rated residual current of 300 mA and a rated current of 16 A, engineered for reliable earth fault detection in single-phase AC installations. This 2-pole device continuously monitors residual currents and provides a changeover contact for signaling or load disconnection. Its compact 2-module DIN rail housing ensures quick installation in distribution boards, while the screw terminals accommodate conductors up to 16 mm² for secure, low-maintenance connections. Compliant with IEC/EN 62020, it is suitable for residential, commercial, and light industrial applications where protection against indirect contact and fire hazards is required.

Advantages

Type A residual current detection covers alternating and pulsating DC fault currents, ensuring comprehensive protection for modern electrical loads. The integrated changeover contact (1 NO/NC) enables flexible integration into control circuits, alarm systems, or shunt trip mechanisms. With a width of only 2 TE (approx. 35 mm), it saves valuable space in the distribution board. The device operates across a wide temperature range from -25 °C to +50 °C, making it suitable for challenging environments. Screw terminals with a large clamping range from 1.5 to 16 mm² (main circuit) and 0.75 to 2.5 mm² (auxiliary circuit) simplify wiring and reduce installation time.
