SIRIUS S00 power contactor — panel fit and switching duty
It snaps onto a 35 mm DIN rail per EN 50022 and occupies a 45 mm width, with a depth of 72 mm and height of 57.5 mm — a compact footprint that fits standard panel layouts without crowding adjacent devices. The AC-4 rating of 8.5 A at 400 V defines its capability for frequent inching and plugging duty on motor loads — the harshest switching condition for a contactor, where it must make and break stalled-rotor current. The AC-12 rating of 10 A covers resistive and lightly inductive loads like heaters or control transformers. The IP20 finger protection on the front and terminals means it is safe for open-panel installation inside an enclosure — no additional shrouding required for basic touch protection.
Coordination and environment — fuse sizing and temperature range
These values govern the upstream protection device selection — match them to avoid nuisance trips or inadequate fault clearing.
