Its adjustable current response range is 18 to 25 A, and it's rated for a rated operational current of 25 A at 690 V, 50-60 Hz. It mounts directly onto a SIRIUS S2-size contactor (company-specific combination size S2), so it's a matched set with the contactor — no separate bracket or wiring harness needed for the power circuit.
Mounting is via contactor mounting — it snaps onto the SIRIUS S2 contactor. The mounting position allows a vertical mounting surface with ±135° rotation and ±45° tilt front-to-back, giving flexibility in tight panels. Dimensions: 105 mm high, 55 mm wide, 118 mm deep. The width is the key panel-space number — at 55 mm, it's a single-unit-wide footprint on the DIN rail when combined with its contactor. Requires 6 mm spacing to grounded parts at the side for proper heat dissipation and clearance.
Main circuit terminals are screw-type, top and bottom, accepting 2×(0.5-1.5 mm²) solid/stranded or 2×(0.75-2.5 mm²) finely stranded with ferrules, or AWG 2×(18-3) and 1×(18-1). Tightening torque is 3-5 N·m. Auxiliary/control circuit terminals are also screw-type, accepting 2×(20-16) AWG or 2×(18-14) AWG. For short-circuit protection of the auxiliary switch, use a gL/gG 6 A fuse or a quick-acting 10 A fuse.
Relative humidity from 0 to 100% is allowed during operation — no derating needed for high-humidity environments. Shock resistance per IEC 60068-2-27 is 8g for 10 ms. Installation altitude is limited to 2000 m above sea level without derating. RoHS compliance date is July 1, 2006 — the part meets the original RoHS directive. Surge voltage resistance is 6 kV, and insulation voltage at pollution degree 3 is 690 V AC.
