Product details

It is designed for control-circuit switching in motor starter assemblies, panel interlocking, and signal routing — not for direct motor load switching. The 10 A AC-12 rating at 230 V covers resistive control loads like PLC inputs, relay coils, and indicator lamps. Screw and snap-on mounting onto a DIN rail keeps integration quick in a standard panel.

Four NO contacts give you four independent switching paths — enough to signal a PLC, a status lamp, and an interlock from one auxiliary block. The AC-12 maximum operating current of 10 A at 230 V is the resistive-load ceiling; derate for inductive or DC loads using the per-voltage values: 1 A at 110 V, 0.27 A at 220 V, 6 A at 230 V, 3 A at 400 V, 2 A at 500 V, and 1 A at 690 V. At 24 V the contact is rated 10 A. The 30 million mechanical operations typical life means this contactor will outlast most panel refreshes in normal cycling.

Dimensions are 45 mm wide, 57.5 mm high, 72 mm deep — fits a standard S00 footprint. Front side carries an IP20 degree of protection, so it's touch-safe for panel use but not for washdown. Rated for installation altitudes up to 2000 m and pollution degree 3. Shock resistance is 10g / 5 ms and 5g / 10 ms.

Wiring and coil data

Terminals accept solid conductors: 2x (0.5... 1.5 mm²), 2x (0.75... 2.5 mm²), and 2x 4 mm². Coil operates at 50 Hz and 60 Hz; the rated voltage range at 50 Hz is 0.8... 1.1 times nominal, at 60 Hz 0.85... 1.1 times nominal. No leading, delayed, or lagging switching contacts — all four are standard instantaneous NO.

Frequently asked questions

Where can I buy 3RH1140-1AP00-1AA0 and how is it quoted?

This part is sourced to order against an RFQ through our independent distribution network. Availability and current pricing are confirmed at quote time — submit a request for a firm quotation.

What are the key ratings of 3RH1140-1AP00-1AA0?

It is a 4 NO auxiliary contactor rated 10 A AC-12 at 230 V, size S00, with screw/snap-on DIN-rail mounting, IP20 front protection, and a mechanical life of 30 million operations.

Will 3RH1140-1AP00-1AA0 drop into a panel specified around 3RT1017-1AP01?

Both are S00 size with the same 45 mm width, 57.5 mm height, and 72 mm depth, so the physical footprint and DIN-rail clip are identical. The 3RH1140 is an auxiliary contactor (4 NO, no main power contacts), while the 3RT1017 is a power contactor with main poles — they serve different functions but share the same mounting hole pattern and terminal layout.
