Product details

It carries 3 normally-open and 1 normally-closed instantaneous contacts, rated 10 A in AC-12 duty (resistive loads at 24 V), with a rated surge voltage resistance of 6 kV. The AC-12 rating governs its use for switching resistive loads in control circuits — think PLC outputs, relay coils, or indicator lamps — not motor starting. The 10 A figure at 24 V is the continuous thermal current; derate for higher voltages per the switching capacity curve (1 A at 110 V, 0.27 A at 220 V).

The S00 frame measures 45 mm wide by 57.5 mm deep by 72 mm tall — a compact footprint that fits standard DIN-rail enclosures. Fastening is via screw or snap-on mounting; the snap-on option allows tool-less rail attachment, useful during panel assembly. Wire termination accepts solid conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or 2x 4 mm² per terminal. For AWG: 2x (20...16), 2x (18...14), or 1x 12.

Environmental and reliability specs

Shock resistance is rated at 10g for 5 ms and 5g for 10 ms. The mechanical endurance is 30 million operations typical.

Frequently asked questions

What compliance documentation is available for this part?

RoHS compliance is confirmed with a substance prohibition date of July 1, 2006. The part is designed to meet IEC/EN standards for industrial control equipment. Certification documentation (declaration of conformity, RoHS report) is available through the authorized Siemens distributor chain.

What is the depth of this auxiliary contactor?

The depth is 72 mm. Combined with a width of 45 mm and height of 57.5 mm, this S00 frame fits standard DIN-rail enclosures and leaves room for adjacent devices in a dense panel layout.

What wire sizes does the terminal accept?

Solid conductors: 2x (0.5...1.5 mm²), 2x (0.75...2.5 mm²), or 2x 4 mm² per clamp. AWG equivalents: 2x (20...16), 2x (18...14), or 1x 12. The spring-cage or screw terminals (depending on variant) accept ferruled stranded as well.

How does this compare to the 3RT1017-1AP01 contactor?

The 3RT1017-1AP01 is a main power contactor (size S00, 7 A AC-3 at 400 V) for switching motor loads. The 3RH1131-1AF10-ZX95 is an auxiliary contactor — it has no main power contacts and is designed to mirror the state of a main contactor or provide additional signal contacts. They share the same S00 frame and mounting footprint, so the auxiliary contactor can snap onto the main contactor or mount adjacent on the same DIN rail without rewiring the panel layout. The key difference: one switches motor current, the other switches control signals.
