Standing mounting position on a horizontal surface is specified; derate if you must mount on its side. ## Switching Ratings and Mechanical Life Rated operational current at 24 V is 10 A; at 400 V it is 3 A. The contactor is also rated for 2 hp at 230 V. For AC-4 duty (plugging / inching) the maximum switching frequency drops to 250 1/h; stay within that for severe switching applications. ## Terminal Capacity and Auxiliary Contacts Spring-type terminals accept solid or stranded conductors from 0.5 to 4 mm², or 2x (0.5 to 4 mm²) for looping through.","metaTitle":"Siemens SIRIUS 3RT2017-2BB42-1AA0-ZX95 Power Contactor, Size","metaDescription":"Siemens SIRIUS 3RT2017-2BB42-1AA0-ZX95 power contactor, size S00, 24 VDC coil, spring-type terminals.

The key difference is the coil termination: the -ZX95 uses spring-type terminals, while the -ZW96 uses screw-type terminals. Panel fit and switching ratings are otherwise identical — no rewiring of the power circuit is needed, but the coil connection method differs."},{"question":"What is the depth of 3RT2017-2BB42-1AA0-ZX95?","answer":"The depth is 73 mm. Combined with a width of 45 mm and height of 70 mm, this is a compact S00 footprint that fits standard 35 mm DIN rail enclosures."},{"question":"What conductor sizes does the spring terminal accept?","answer":"Solid or stranded conductors from 0.5 to 4 mm², and 2x (0.5 to 4 mm²) for looping through.
