It uses spring-loaded terminals — no screwdriver needed for the control wiring, which speeds up panel assembly and stays tight under vibration on a conveyor line or pump panel. Rated 10 A at 24 V for general-purpose use, but the AC-15 rating at 690 V is 1 A — that's the figure that governs switching solenoids and contactor coils in a 480 V panel. The 6 kV surge voltage resistance (rated impulse withstand) means it coordinates with standard industrial control transformers and doesn't need extra suppression for most PLC outputs. Mechanical life is 10 million cycles typical; the spring terminals don't wear out from repeated wiring changes during commissioning. Snap-on mounting to the contactor front — no tools, no DIN rail. The block adds 36 mm width and 47.7 mm depth to the assembly; check your enclosure depth if the contactor is already tight against the gland plate. Wire capacity is 2x 0.5–2.5 mm² without ferrules, or 2x 0.5–1.5 mm² with ferrules; AWG 20–14 for the US installs. Strip length is the standard 8–10 mm for spring-cage terminals.","metaTitle":"Siemens 3RH2911-2HA01-ZX95 Auxiliary Switch, 1 NC, Spring-Lo","metaDescription":"Siemens SIRIUS auxiliary switch for 3RT2/3RH2 contactors. 1 NC, spring-loaded terminals, rated 10 A.
