Product details

The coil holds at 24 VDC nominal; dropout occurs below the pick-up threshold, so verify your control supply stays above that during brownout conditions.

Mounting and Clearance — DIN Rail Fit

The contactor measures 45 mm wide by 70 mm tall by 73 mm deep — a compact S00 footprint that leaves room alongside overload relays and busbars. Standing mounting position on a horizontal surface is specified; derate if you must mount on its side.

Switching Ratings and Mechanical Life

Rated operational current at 24 V is 10 A; at 400 V it is 3 A. The contactor is also rated for 2 hp at 230 V. For AC-4 duty (plugging / inching) the maximum switching frequency drops to 250 1/h; stay within that for severe switching applications.

Terminal Capacity and Auxiliary Contacts

Spring-type terminals accept solid or stranded conductors from 0.5 to 4 mm², or 2x (0.5 to 4 mm²) for looping through.

Frequently asked questions

Where can I buy 3RT2017-2BB42-1AA0-ZX95?

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 a firm commitment.

What is the closest functional alternative to 3RT2017-2BB42-1AA0-ZX95?

The closest functional peer is 3RT2017-2AH02-ZW96, which shares the same SIRIUS size S00 frame and 24 VDC coil voltage. The key difference is the coil termination: the -ZX95 uses spring-type terminals, while the -ZW96 uses screw-type terminals. Panel fit and switching ratings are otherwise identical — no rewiring of the power circuit is needed, but the coil connection method differs.

What is the depth of 3RT2017-2BB42-1AA0-ZX95?

The depth is 73 mm. Combined with a width of 45 mm and height of 70 mm, this is a compact S00 footprint that fits standard 35 mm DIN rail enclosures.

What conductor sizes does the spring terminal accept?

Solid or stranded conductors from 0.5 to 4 mm², and 2x (0.5 to 4 mm²) for looping through. The spring-type terminals require no screw tightening — strip to the correct length and push in.

Will 3RT2017-2BB42-1AA0-ZX95 drop into a panel specified for 3RT2017-2AH02-ZW96?

Yes — same SIRIUS size S00 frame, same 45 mm width, same mounting rail and clearance requirements. The only difference is the coil termination: spring-type on this -ZX95 versus screw-type on the -ZW96. No rewiring of the power circuit is needed, but the coil connection method changes.
