Product details

It's the switching element you add to a contactor or starter to pick up control signals, status feedback, or interlock logic — not a power-switching device itself. Rated for 10 A at 24 V and 6 A at 230 V on the AC side, with DC ratings down to 0.26 A at 600 V.

The S00 footprint — 45 mm wide, 57.5 mm tall, 117 mm deep — is the smallest SIRIUS contactor frame, so it slides into tight panel layouts. Terminal accepts 2× (0.5 to 1.5 mm²), 2× (0.75 to 2.5 mm²), or 2× 4 mm² solid or stranded wire.

Minimum relative humidity 10%. RoHS compliance date of July 1, 2006 — the part meets EU RoHS requirements.
