The 230 V AC coil is a standard industrial control voltage across Europe and much of Asia. The AC-12 rating is the headline number that governs the fit: 10 A at the rated insulation voltage. That's not a motor-switching figure — for motor loads you'd look at the AC-3 or AC-4 ratings, which are lower for this frame size. At 230 V the contactor is rated for 6 A (AC-1), and at 400 V for 3 A (AC-1). The 45 mm width (one HP, or horizontal pitch) means it occupies a single 9 mm module space on the rail. Depth is 73 mm, height 60 mm, so it clears most shallow enclosures. Side-by-side mounting is permitted, which is useful when packing multiple contactors into a tight gland plate layout. Main circuit connections are spring-loaded terminals, accepting 2x (0.25 to 2.5 mm²) solid or stranded wire, or 2x (24 to 14 AWG). Spring-cage terminations are faster to wire than screw clamps and hold well under vibration — worth noting if the panel sees transport or machine-mounted duty. It's not a clean-room part, but it's not meant for outdoor exposure either. The AC-12 rating of 10 A sets the thermal current limit for resistive loads — don't exceed that. For motor loads, the relevant figure is the AC-3 rating (not explicitly listed here but typically around 4 kW at 400 V for S00 frame). The coil draw is 3.3 W both closing and holding — a DC-operated coil that stays cool in continuous service. That's a high figure — for a contactor switching once per minute, that's about 57 years of continuous operation. Electrical life will be lower and depends on the switched load; the AC-12 figure is the best case.","metaTitle":"Siemens SIRIUS 3RT1015-2BP42 Power Contactor, S00, 10A AC-12","metaDescription":"Siemens SIRIUS 3RT1015-2BP42 power contactor, size S00, rated 10 A AC-12, 230 V AC coil.

The key difference is the coil voltage: the -2BP42 has a 230 V AC coil, while the -1BB42 uses a 24 V DC coil. The main contact ratings and frame size (S00) are identical. If your control circuit runs on 24 VDC, the -1BB42 is a drop-in replacement on the same DIN rail footprint without rewiring the power circuit."},{"question":"Will the 3RT1015-2BP42 fit in a panel designed for the 3RT1015-1BB42?","answer":"Yes, it will drop into the same panel without mechanical changes. Both are size S00 contactors with the same 45 mm width, 60 mm height, and 73 mm depth. The mounting rail and side-by-side clearance are identical. The only difference is the coil supply — the -2BP42 needs 230 V AC, the -1BB42 needs 24 V DC. Verify the control transformer and wiring before swapping."},{"question":"What compliance documentation is available for the 3RT1015-2BP42?","answer":"As a Siemens SIRIUS product, the contactor carries CE marking for the European market and is designed to meet IEC/EN 60947-4-1 standards. UL and CSA approvals are typical for the series, though specific certification for this exact order code should be verified against the nameplate.
