Screw-type terminals accept 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) with core-end processing, or AWG 20–16 and 18–14 for the auxiliary circuit. Rated operational current hits 10 A maximum, with specific thermal current ratings across the voltage range: 6 A at 24 V AC/DC, 6 A at 125 V, 6 A at 230 V, 3 A at 400 V, and 0.3 A at 220 V. The AC-15 utilization category at 690 V is rated at 1 A — that's the inductive load switching capacity for solenoid and contactor coils at line voltage. Insulation voltage is 690 V with pollution degree 3, surge voltage resistance 6 kV. Mechanical service life is typical 10 million switching cycles. Storage temperature range -55 to +80 °C; operating ambient -25 to +60 °C. Front face is IP20 protected. The 3RH1911-1GA13-ZW97 is a phased-out product. The official Siemens successor is the SIRIUS 3RH2 series auxiliary switch blocks. No last-time-buy window remains open from the factory. The -ZW97 suffix indicates multi-unit packaging (140 units per pack), so a single order code covers a full panel build quantity. If your panel drawing references this specific variant, the 3RH2 successor may require a footprint or wiring check before substitution. Snap-on mounting onto 35 mm DIN rail, dimensions 36.5 mm wide × 37.5 mm high × 41.5 mm deep. The block stacks directly onto SIRIUS contactor relays (3RH1 base devices) and power contactors. Screw terminals are accessible with a standard Pozidriv No. 2 bit; strip length 8 mm for solid or ferruled stranded conductors. The 1 NO + 3 NC arrangement per EN 50011 (53 E) gives three breaks for safety-circuit isolation and one make for a feedback signal.","metaTitle":"Siemens 3RH1911-1GA13-ZW97 Auxiliary Switch Block, 1NO+3NC,","metaDescription":"Siemens SIRIUS 3RH1911-1GA13-ZW97 auxiliary switch block, 1 NO + 3 NC, 10 A rated, AC-15 690 V 1 A, IP20, snap-on.
