Product details

It is designed for control-circuit switching — signalling, interlocking, and logic-level isolation inside a motor control centre or panel — not for direct motor loads. Rated operational current reaches 10 A at 230 V AC (50/60 Hz) and 10 A at 24 V DC, with lower ratings at higher voltages: 3 A at 400 V AC, 1 A at 690 V AC, and 0.26 A at 600 V DC.

The S00 footprint — 45 mm wide, 70 mm high, 73 mm deep — fits standard DIN-rail spacing; allow 10 mm clearance above and below, 10 mm forward, and 6 mm at the sides for airflow and wiring access.
