Size S00 coupling contactor with spring terminals
The Siemens 3RT2016-2JB41-ZX95 is a SIRIUS coupling contactor in size S00, designed for switching loads in control panels where space is tight — the 45 mm width and 73 mm depth fit standard DIN-rail enclosures without crowding adjacent devices. The coil is rated 24 V DC, pulling 10 A at that rated value, with spring-type terminals accepting solid or stranded wire from 0.5 to 4 mm² — no screw torque to verify, just strip and push.
Switching frequency and mounting flexibility
Maximum switching rate at AC-3 duty is 750 operations per hour, dropping to 250 per hour at AC-4 — the higher arc energy in motor inrush or plugging duty limits the mechanical cycle rate. Mounting position allows ±180° rotation on a vertical surface and ±22.5° tilt forward or backward, so the contactor can be oriented to fit the wireway layout without derating the coil or contacts. Operating temperature range is -25 to +60 °C, with storage from -55 to +80 °C — suitable for unheated enclosures in temperate climates as long as condensation is managed.
