Product details

The Siemens 3RT1015-2BB42-ZW97 is a SIRIUS power contactor in frame size S00, rated for a 24 VDC coil with a pick-up threshold of 0.85 and drop-out at 1.1 of rated voltage. It switches motor loads up to 4 kW at 690 V (AC-3 equivalent) and handles resistive loads to 10 A at 24 V. The main circuit uses spring-loaded terminals accepting 2x (0.25... 2.5 mm²) solid or stranded wire, or 2x (24... 14) AWG.

Coordination and short-circuit protection

For type 2 coordination (no weld-stick after fault), use a gL/gG fuse rated 20 A. For type 1 coordination (device may be damaged but circuit clears), the fuse can be 35 A gL/gG.

Frequently asked questions

What is the closest functional alternative to 3RT1015-2BB42-ZW97?

The 3RT1015-1BB42 is the screw-terminal sibling — same S00 frame, same 24 VDC coil, same power ratings. The -ZW97 variant uses spring-loaded terminals on the main circuit; the -1BB42 uses screw terminals. If your panel was wired for screw terminals, the spring-clamp version drops into the same DIN footprint without rewiring the mounting, but you will need to adapt the conductor termination method.

Where can I buy 3RT1015-2BB42-ZW97 and get current pricing?

This part is sourced and quoted to order against an RFQ through independent distribution channels. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm price and lead time.

What compliance documentation is available for 3RT1015-2BB42-ZW97?

As a standard Siemens SIRIUS catalog item, it carries CE marking for the European market and is designed to meet RoHS and REACH requirements. The reference code per DIN EN 81346-2 is Q. Specific UL/CSA file numbers and declaration of conformity documents are available on request with the RFQ.
