Rated at 1.6 A operational current in AC-3 duty (switching motor loads up to that current at 400 V), it uses a magnetic short-circuit trip that responds at 21 A, so it clears a fault before the contactor welds.
At 45 mm wide, 97 mm tall, and 96 mm deep, it fits the standard S00 footprint; clearance of 50 mm above and below, 30 mm to the sides keeps airflow and wiring access clean.
Electrical Ratings and Environment
Rated for 690 V insulation voltage (pollution degree 3) and 6 kV surge withstand, it handles standard industrial supply voltages. Operating temperature spans -20 to +60 °C, storage from -50 to +80 °C, with 10–95 % relative humidity. Shock rated at 25 g / 11 ms per IEC 60068-2-27 — tough enough for machine-mounted applications. Total power loss is 6 W typical.
Substance prohibitance (RoHS-compliant) dated May 1, 2012. The SIRIUS series carries UL, CSA, and IEC certifications standard for the line — compliance documentation (declarations, CE marking) is available with the product.
