For motor loads, the contactor is rated 3 hp at 230 V, 7.5 hp at 200/208 V, 7.5 hp at 220/230 V, 15 hp at 460/480 V, and 20 hp at 575/600 V. At 400 V it switches 3 A in AC-4 duty (15.5 A), meaning it handles the high-stress reversing or inching cycles where the contacts break full motor current. The contactor measures 45 mm wide, 119 mm tall, and 150 mm deep. The front face carries an IP20 rating (finger-safe), while the terminals themselves are IP00 — meaning the wiring compartment is open and needs enclosure protection in dusty or wet environments.","metaTitle":"Siemens 3RT1026-3XB44-0LA2 SIRIUS Power Contactor, 24 VDC, S","metaDescription":"Siemens 3RT1026-3XB44-0LA2 SIRIUS power contactor, S0 frame, 24 VDC coil, screw terminals, snap-on DIN rail.

The 3RT1026-3XB44-0LA2 carries a 24 VDC coil and two instantaneous auxiliary contacts; the 3RT1026-1AB00 uses a different coil voltage. Verify coil compatibility before swapping."},{"question":"What is the depth of 3RT1026-3XB44-0LA2?","answer":"The depth is 150 mm, which is standard for the S0 frame size and fits most DIN-rail enclosures with that clearance."},{"question":"What wire sizes does the 3RT1026-3XB44-0LA2 accept?","answer":"The solid/stranded terminals accept 2x (0.25... 2.5 mm²) for auxiliary wiring, and the main circuit terminals accept 2x (1... 2.5 mm²), 2x (2.5... 6 mm²), or max. 2x 10 mm²."},{"question":"Will 3RT1026-3XB44-0LA2 drop into a panel specified around 3RT1026-1AB00 without rewiring?","answer":"Mechanically yes — both are S0 frame, same DIN-rail footprint and screw-terminal layout. Electrically no: the coil voltage differs (24 VDC vs the 1AB00's coil), so the control circuit must match.
