For reversing or inching duty (AC-4), it carries 15.5 A at 400 V — a figure that governs contact life in frequent-switching applications. Auxiliary contacts are rated 10 A at 24 V, 6 A at 230 V, and 0.3 A at 220 V, covering PLC-level signal switching and control circuit isolation. The IP20 front and IP00 terminal area mean the body is finger-safe when panel-mounted; wiring terminations require enclosure protection. ## Integration notes The 45 x 85 x 91 mm (W x H x D) footprint fits a standard S0 contactor slot. Side-by-side mounting is permitted with 6 mm spacing, so multiple contactors can pack tightly on a DIN rail without derating — useful for multi-motor MCC sections. Screw terminals on the main circuit accept 2x (1 to 2.5 mm²) solid or stranded, up to 2x 10 mm² max. The auxiliary circuit uses smaller terminals: 2x (0.5 to 1.5 mm²) solid. For Type 2 coordination (no-weld on fault), specify a 25 A gL/gG fuse upstream; for Type 1 (replace after fault), a 63 A fuse is allowed.","metaTitle":"Siemens 3RT1025-1AK60-ZW97 SIRIUS Power Contactor, S0, 7.5 k","metaDescription":"Siemens SIRIUS 3RT1025-1AK60-ZW97 power contactor, size S0, 7.5 kW at 400 V AC-2, 45 mm wide, IP20 front, screw terminals, current production.

The 3RT1025-1AK60-ZW97 carries higher AC-2 power (7.5 kW vs the 3RT1023's lower rating at 400 V), so it can replace the smaller unit if the load is within its ratings.

RoHS and REACH compliance declarations are standard from Siemens for current-production catalog items.
