Product details

Panel-fit and terminal constraints

The 3RT1015-2BB41 is a SIRIUS S00-frame power contactor — 45 mm wide, 60 mm tall, 73 mm deep — sized for a 35 mm DIN rail (EN 50022) with screw or snap-on fastening. Spring-loaded terminals on both the main and auxiliary/control circuits accept 2x (0.25...2.5 mm²) solid or stranded, or 2x (24...14 AWG). The front face carries IP20, so panel builders can route wiring without finger-safety covers at the operator interface.

Coil and switching duty

Coil is 24 VDC rated, pickup at 0.85x nominal (20.4 V), dropout at 1.1x (26.4 V). Closing and holding power both 3.3 W — the magnet circuit is a DC economized design, so the coil draw does not spike on seal-in. For motor switching: AC-2 duty (slip-ring motors, wound-rotor lifts) is 3 kW at 400 V; AC-4 duty (plugging, inching) is 6.5 A at 400 V. The AC-12 maximum operational current is 10 A for resistive loads on the auxiliary side.

Frequently asked questions

Where can I buy 3RT1015-2BB41 and how do I get a price?

This part is sourced to order against an RFQ through independent distribution channels. Submit an RFQ for current availability and pricing — confirmed at quote time.

What is 3RT1015-2BB41's depth?

The depth is 73 mm, with a width of 45 mm and height of 60 mm — fits the S00 frame footprint on a 35 mm DIN rail.

Will 3RT1015-2BB41 drop into a panel specified for 3RT1015-1BB42 without rewiring?

Both are S00-frame contactors on a 35 mm DIN rail. The 3RT1015-2BB41 uses spring-loaded terminals; the 3RT1015-1BB42 uses screw-type terminals. The panel cutout and rail position are identical, but the wiring termination method differs — existing ring or fork lugs for screw terminals may not suit the spring cage. Verify the terminal interface before drop-in replacement.
