Product details

Its 2-pole (1P+N) configuration switches both phase and neutral, making it suitable for single-phase AC loads up to 250 V at 50/60 Hz. Rated breaking capacity is 6 kA per EN 60898 and 5 kA per UL 1077 / CSA C22.2 No.235, so it handles fault currents up to those levels without cascading upstream.

Combined terminal at both top and bottom accepts wiring without separate busbar connectors. Neutral conductor switching is built in, so no external neutral link is needed for the switched neutral pole. IP20 with connected conductors; keep the panel door closed during operation.

Thermal derating and environmental limits

Rated 0.3 A at 35 °C, but the current must be derated as ambient temperature rises: 0.28 A at 40 °C, 0.26 A at 45 °C, 0.25 A at 50 °C, and 0.23 A at 55 °C. If the panel runs hot (say, 50 °C internal), size the circuit for 0.25 A continuous, not the nameplate 0.3 A. Operating range is -40 to 75 °C, with humidity limits of 95% up to 55 °C, tapering to 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz, so it holds up on machinery near motors or conveyors.

Rated for mechanical engineering and industry applications per the manufacturer's suitability listing.
