Rated for a maximum of 10 A, with specific current ratings across voltages: 10 A at 24 V, 6 A at 24 V, 125 V, 230 V, and 250 V; 4.7 A at 60 V; 3 A at 400 V; and lower ratings at higher voltages up to 600 V. The block snaps onto a contactor relay or power contactor. Dimensions are 36.5 mm wide, 37.5 mm high, and 41.5 mm deep. The front has IP20 protection, so it's suited for enclosed control panels where no washdown or outdoor exposure occurs. The screw terminals accept 2x (0.5... 1.5 mm²) or 2x (0.75... 2.5 mm²) with core end processing, or 2x (20... 16) or 2x (18... 14) AWG. The 10 A maximum rating at AC-15 duty governs switching of solenoid loads like contactor coils — the typical application for an auxiliary block. The 4 NC configuration follows EN 50011, providing normally-closed feedback for safety circuits or status monitoring. The 6 kV surge voltage resistance and 690 V insulation voltage at pollution degree 3 mean this block is rated for industrial environments with moderate contamination, not just clean office panels.","metaTitle":"Siemens 3RH1911-1GA04-ZX95 Auxiliary Switch Block, 10 A","metaDescription":"Siemens SIRIUS 3RH1911-1GA04-ZX95 auxiliary switch block. 4 NC contacts, 10 A max, screw terminals, snap-on mounting.
