Short-circuit coordination is specified: Type 2 coordination requires a 20 A gL/gG fuse; Type 1 allows a 35 A gL/gG fuse. This matters when the contactor sits downstream of a branch circuit protector — the fuse size determines whether the contactor survives a fault or needs replacement. The 45 mm wide, 57.5 mm high, 72 mm deep footprint fits the S00 frame standard. Side-by-side mounting is permitted with 6 mm spacing to adjacent devices, so multiple contactors pack tightly on a DIN rail without derating. Screw terminals on the main circuit accept 2x (0.5 to 1.5 mm²) solid, 2x (0.75 to 2.5 mm²), or max 2x (0.75 to 4 mm²) — covering standard control wiring up to 4 mm² for motor feeders. Altitude limit is 2 000 m; above that, dielectric withstand and cooling derate per IEC 60947.","metaTitle":"Siemens 3RT1017-1HB42-ZX95 SIRIUS Contactor, 24 V DC, Size S","metaDescription":"Siemens SIRIUS 3RT1017-1HB42-ZX95 power contactor, Size S00, 24 V DC coil, 5.5 kW at 400 V AC-2.
