Product details

Rated mechanical endurance is 30 million operations, with contact reliability of one incorrect switching per 100 million at 17 V, 1 mA. The IP20 front protection suits enclosed control panels; pollution degree 3 covers industrial environments with conductive pollution.

For switching loads, the contact ratings vary by voltage: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. The 6 kV surge voltage resistance ensures coordination with upstream surge protection in industrial panels. Terminals accept solid conductors: 2x 0.5–1.5 mm², 2x 0.75–2.5 mm², and 2x 4 mm² (or AWG equivalents 2x 20–16, 2x 18–14, 1x 12). The clamping range covers most control wiring gauges used in panel builds. Depth is 72 mm, width 45 mm, height 57.5 mm — compact enough for dense DIN-rail layouts.

Fastening is screw or snap-on onto a DIN rail — no adapter needed. The size S00 body fits standard 45 mm wide slots. Shock resistance rated 10g / 5 ms and 5g / 10 ms.

Frequently asked questions

What is the closest functional second-source to 3RH1140-1BB40-0TK0-ZX95?

The 3RH2140-1BP40 is a peer auxiliary contactor in the same SIRIUS family, but it uses a different coil voltage and contact arrangement — verify your control voltage and contact count before substituting. The 3RH1140-1BB40-0TK0-ZX95 is a 24 V DC, 4 NO configuration; the 3RH2140-1BP40 differs in coil and contact specs.

Where can I buy 3RH1140-1BB40-0TK0-ZX95?

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 your volume.

What compliance documentation does 3RH1140-1BB40-0TK0-ZX95 have?

RoHS compliance date is July 1, 2006, covering substance prohibitions. The part carries IP20 front protection and pollution degree 3 rating. Surge voltage resistance is 6 kV.

Will 3RH1140-1BB40-0TK0-ZX95 drop into a panel specified around 3RH2140-1BP40 without rewiring?

Both are size S00 with the same DIN-rail footprint, so mechanical fit is the same. However, the coil voltage and contact configuration differ — verify your control circuit voltage and NO/NC count before swapping.
