The contact block carries 2 NO instantaneous contacts and 2 NC contacts, rated 10 A at AC-12 (resistive) and 6 A at 230 V, 3 A at 400 V, 1 A at 690 V. That means it handles typical 24 VDC pilot-duty loads easily, and the 690 V rating covers most 3-phase control circuits without derating concerns. ## Wiring and compliance Surge voltage resistance rated at 6 kV, which aligns with IEC 60947-1 overvoltage category III for industrial control circuits. The part carries the SIRIUS brand and is designed for use with Siemens S00 contactor systems.","metaTitle":"Siemens 3RH1122-2BB40-ZX95 SIRIUS Auxiliary Contactor, 24 VD","metaDescription":"Siemens 3RH1122-2BB40-ZX95 SIRIUS auxiliary contactor, 24 VDC coil, 10 A AC-12 rated, 2 NO + 2 NC contacts, screw/snap-on mount, size S00, IP20.

Availability and current pricing are confirmed at quote time through independent distribution channels — no stock figures or lead-time numbers are published here."},{"question":"What is 3RH1122-2BB40-ZX95's listed depth on this component line?","answer":"The depth is 73 mm, with a width of 45 mm and height of 60 mm. Zero side clearance is required, so adjacent units can mount flush."},{"question":"What wire sizes does 3RH1122-2BB40-ZX95 accept?","answer":"Solid and stranded wire from 0.25 mm² to 2.5 mm². The screw terminals accept both solid and ferruled stranded conductors within that range."},{"question":"Will 3RH1122-2BB40-ZX95 drop into a panel that was specified around 3RT1015-1BB42 without rewiring?","answer":"Not directly — the 3RT1015-1BB42 is a power contactor, while the 3RH1122-2BB40-ZX95 is an auxiliary contactor. The physical footprint (size S00) and DIN-rail mounting are the same, but the 3RT carries main power contacts and the 3RH carries only auxiliary contacts. If the panel needs auxiliary contacts for a 3RT, this part is the correct add-on; if it needs a replacement power contactor, this is the wrong part."},{"question":"What compliance documentation does this brand provide for 3RH1122-2BB40-ZX95?","answer":"Standard SIRIUS series documentation includes RoHS, REACH, and UL/IEC declarations. The surge voltage rating of 6 kV and pollution degree 3 indicate compliance with IEC 60947-1 overvoltage category III.
