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.","metaTitle":"Siemens SIRIUS 3RH1131-1AF10-ZX95 Auxiliary Contactor, 10 A","metaDescription":"Siemens SIRIUS 3RH1131-1AF10-ZX95 auxiliary contactor, 10 A AC-12, 3 NO + 1 NC, size S00, screw/snap-on mount.

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."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RH1131-1AF10-ZX95","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RH1131-1AF10-ZX95 when reusing this data.
