Product details

SIRIUS 3RT1015-2WB41 — 24 VDC Coil, Size S00 Power Contactor

The Siemens SIRIUS 3RT1015-2WB41 is a Size S00 power contactor with a 24 V DC magnet coil, designed for screw and snap-on mounting onto 35 mm DIN rail per EN 50022. It carries a varistor surge suppressor built into the coil circuit — no separate suppressor module needed for basic transient protection. Main power terminals are spring-loaded, accepting 2x (0.25 to 2.5 mm²) solid or stranded conductors (2x 24–14 AWG). The contactor measures 45 mm wide by 60 mm high by 73 mm deep — fits a standard 45 mm DIN-rail slot with 6 mm side clearance for heat dissipation when mounted side-by-side.

Switching Ratings by Duty

Rated operational currents vary significantly by duty cycle and voltage. At AC-3 (squirrel-cage motors: starting, switching off running motors) the contactor delivers 5.5 kW at 400 V, 3.5 kW at 500 V, and 4 kW at 690 V. AC-4 duty (inching, plugging, reversing) at 400 V is rated 6.5 A. For resistive loads (AC-1 / AC-12) the maximum operating current is 10 A at 24 V and 6 A at 230 V. DC switching ratings: 10 A at 24 V, 2 A at 60 V, 1 A at 110 V, 0.3 A at 220 V. The coil draws 1.4 W closing and 1.4 W holding — a DC economizer is not required since holding power equals pick-up power.

Type 1 coordination (no damage to contactor, but may need contact replacement) requires a 35 A gL/gG fuse.

Frequently asked questions

Where can I buy 3RT1015-2WB41?

This part is sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for your quantity and delivery window.

What is the closest functional alternative to 3RT1015-2WB41?

The 3RT1015-1BB42 is the closest functional peer — same Size S00 frame, same 24 V DC coil voltage, but with screw terminals instead of spring-loaded terminals and without the built-in varistor. Panel footprint is identical (45 mm width), so it drops into the same DIN-rail slot without rewiring the main power circuit.

Does 3RT1015-2WB41 drop into a panel wired for 3RT1015-1BB42?

Yes — both are Size S00 with the same 45 mm width and DIN-rail mounting. The main power terminals differ (spring-loaded on -2WB41 vs screw on -1BB42), but the conductor range is identical (2x 0.25–2.5 mm²). Control wiring for the 24 V DC coil and auxiliary contacts is pin-compatible.

What are the key dimensions of 3RT1015-2WB41?

Width 45 mm, height 60 mm, depth 73 mm. Side clearance of 6 mm is required when mounting side-by-side. The contactor snaps onto 35 mm DIN rail per EN 50022.

What compliance documentation does Siemens provide for 3RT1015-2WB41?

Standard Siemens SIRIUS documentation includes a CE declaration of conformity, RoHS and REACH compliance statements, and UL/CSA file numbers. The contactor carries IP20 protection on the front and terminals.
