It snaps onto the front of the contactor without tools — no extra DIN rail space needed, just a firm push until the latch clicks. Switching capacity depends on the circuit voltage: rated for 10 A at 24 V, 6 A at 230 V, and 3 A at 400 V. At 690 V in AC-15 duty it handles 1 A.
Dimensions: 36.5 mm wide, 37.5 mm tall, 41.5 mm deep — compact enough to fit inside a shallow gland plate or behind a panel door without crowding adjacent devices. The snap-on mount engages the contactor's front profile, so the contactor's own DIN-rail footprint stays unchanged. Terminals are screw-type, accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) with core-end processing, or the AWG equivalents 2x (20 to 16) and 2x (18 to 14). Strip length and torque follow standard Siemens S00 practice — no special tooling needed.
Contact reliability and service life
Rated for 10 million mechanical switching cycles typical. The same reliability spec applies at 1 mA for the auxiliary contacts, so it handles PLC-level signals without the usual wetting-current worry.
Environmental and protection
Surge voltage resistance rated at 6 kV, which is standard for industrial control circuits running alongside contactors and drives.
