It snaps onto the front of the contactor, adding four auxiliary contacts without increasing the panel depth beyond the 46 mm listed depth of the block itself. The spring-loaded terminals accept 2x (0.5 to 1.5 mm²) with ferrule or 2x (0.5 to 2.5 mm²) solid/stranded, so no screwdriver is needed for the connection — a time-saver on a multi-unit panel build. The block carries a maximum thermal current of 10 A, but the real-world switching capability depends on the voltage and duty. At 24 V DC it switches 6 A; at 110 V DC that drops to 1 A. For AC-15 inductive loads (solenoids, contactor coils) at 690 V it's rated 1 A. The insulation is rated 690 V AC with degree of pollution 3, and the surge voltage resistance is 6 kV — that's the impulse-withstand level for a 400 V industrial panel environment. ## Panel integration — snap-on and terminal details The block snaps onto the front of a S00 contactor — no screws, no tools for the mounting. The spring-loaded terminals are the same type used on the 3RH2 series, so the wiring habit transfers.","metaTitle":"Siemens 3RH1911-2FA22-ZW98 SIRIUS Auxiliary Switch Block, 22","metaDescription":"Siemens SIRIUS 3RH1911-2FA22-ZW98 auxiliary switch block, 2 NO + 2 NC, spring-loaded terminals, S00 size.
