SIRIUS S2 power contactor for motor switching
The 55 mm width and 130 mm depth let it fit standard DIN-rail enclosures with predictable spacing.
The 55 mm width and 130 mm depth mean it occupies three to four 18 mm module spaces on the rail, depending on side clearance of 6 mm each side. Main contacts are 18 NO / 1 NC, giving you a normally-open stack for motor power and one normally-closed for status feedback or interlock. An auxiliary switch is built in, so you don't need a separate add-on block for basic signaling.
