Product details

Rated for 3.5 kW at 500 V and 4 kW at 690 V in AC-3 duty — that is the motor-switching rating that governs real-world sizing for pumps, fans, and compressors. The AC-12 operating current is 10 A, covering resistive loads. For AC-4 reversing or inching duty, the contactor is rated 6.5 A at 400 V. Pickup is at 85% of rated voltage (20.4 VDC) and dropout at 110% (26.4 VDC) — ensure your 24 V supply stays within that band under load.

Main circuit terminals are screw-type, accepting 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or max 2x (0.75…4 mm²) solid/stranded. AWG equivalents: 2x (20…16), 2x (18…14), 1x 12. The front and terminal faces carry IP20 finger-safe protection, so the contactor is safe to handle in an open panel.

Coordination and environment

Type 1 coordination requires a 35 A gL/gG fuse; Type 2 requires 20 A.

Frequently asked questions

Where can I buy 3RT1015-1BB42-ZX95?

Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time.

Will 3RT1015-1BB42-ZX95 drop into a panel wired for 3RT1015-1BB42?

Yes — the base 3RT1015-1BB42 and this -ZX95 variant share the same S00 frame, 45 mm width, 57.5 mm height, 72 mm depth, and 24 VDC coil. The -ZX95 suffix indicates a special version (often a customer-specific variant or packaging), but the mechanical footprint and electrical ratings are identical. No rewiring needed.

What is the depth of 3RT1015-1BB42-ZX95?

The depth is 72 mm, fitting standard 35 mm DIN-rail enclosures with clearance for wiring.

What wire sizes does the main terminal accept?

Screw terminals accept 2x (0.5…1.5 mm²), 2x (0.75…2.5 mm²), or max 2x (0.75…4 mm²) solid/stranded. AWG equivalents: 2x (20…16), 2x (18…14), 1x 12.
