It mounts via snap-on onto a DIN rail, with screw-type terminals accepting 2x (0.5 to 1.5 mm²) or 2x (0.75 to 2.5 mm²) conductors, and carries an IP20 protection rating on the front face. The 10 A maximum rating applies across the board, but the real-world switching capacity depends on the voltage and duty. For DC loads, the 24 V DC rating is 10 A, dropping to 4.7 A at 60 V DC, 3 A at 110 V DC, and 1.2 A at 220 V DC. The AC-15 rating at 690 V is 1 A — that's the inductive load curve for solenoid and contactor coils at line voltage. The surge voltage resistance is 6 kV, and the insulation voltage at pollution degree 3 is 690 V AC, so this block is rated for 480 V and 600 V panels without derating the insulation. The block measures 36.5 mm wide, 37.5 mm high, and 41.5 mm deep — it fits the standard SIRIUS contactor footprint and clips directly onto the contactor or relay without extra hardware.","metaTitle":"Siemens 3RH1911-1HA13-ZW98 Auxiliary Switch Block, 10 A, SIR","metaDescription":"Siemens SIRIUS 3RH1911-1HA13-ZW98 auxiliary switch block, 4-pole, 1 NO + 3 NC, 10 A, screw terminals, snap-on mounting.
