Product details

Part identity and key ratings

Rated for AC-12 duty at 10 A maximum, it handles resistive and transformer-coupled loads cleanly. For motor switching under AC-4 at 400 V, it carries 6.5 A — enough for small reversing or inching applications where the contactor sees full load break every cycle. Spring-loaded terminals accept 2x (0.25 to 2.5 mm²) solid or stranded wire, or 2x (24 to 14 AWG). The IP20 finger-safe protection on the front and terminals means it can sit exposed in a panel without additional shrouding.

Side-by-side mounting is permitted with 6 mm spacing at the side, so you can pack several contactors in a row without derating — useful when the panel fill factor is tight.

For Type 1 coordination (contactor may need replacement but the circuit is cleared), the fuse can go up to 35 A. This matters when you're laying out the branch circuit protection for a motor starter combination.

Frequently asked questions

What is the closest functional alternative to the 3RT1015-2BB41-ZX95?

The 3RT1015-1BB42 is a close peer in the same SIRIUS size S00 family, but it uses screw terminals instead of the spring-loaded terminals on the -2BB41-ZX95. If your panel wiring is already spec'd for spring-cage connections, the -2BB41-ZX95 is the direct fit; the -1BB42 would require a terminal adapter or a wiring change.

What is the depth of the 3RT1015-2BB41-ZX95?

The depth is 73 mm, which is standard for the size S00 frame in this SIRIUS series.

What conductor sizes does the spring-loaded terminal accept?

It accepts 2x (0.25 to 2.5 mm²) solid or stranded wire, or 2x (24 to 14 AWG).

Will the 3RT1015-2BB41-ZX95 drop into a panel designed for the 3RT1015-1BB42?

Yes, the mounting footprint and DIN-rail clip are identical between the two — same 45 mm width, same 60 mm height, same snap-on rail profile. The only difference is the terminal type: spring-loaded on the -2BB41-ZX95 versus screw on the -1BB42. No rewiring of the panel layout is needed, but you will need to verify the terminal adapter or wire termination method if the panel was wired for screw clamps.

What compliance documentation is available for this contactor?

As a Siemens SIRIUS product, it carries IEC and EN certifications for industrial control equipment. Specific RoHS, REACH, and UL documentation is available from the manufacturer upon request through the supply channel.
