For resistive loads (AC-1) the limit is higher, but for motor switching the AC-4 number governs the real-life service life. The coil operates at 24 VDC with a rated current of 10 A at 24 V. The integrated RC surge suppressor means you don't need an external snubber for the coil, which simplifies wiring and reduces panel clutter. Spring-loaded terminals accept 2x (0.25... 2.5 mm²) solid or stranded wire — that's up to 14 AWG, enough for most control and small power circuits. The IP20 finger-safe protection on the front and terminals means it's safe for open-panel mounting without additional shrouding. The 3RT1016-2EF04-0KS0-ZX95 is a fast mover for MRO and panel-build applications. Keep it on the shelf as a critical spare for any 24 VDC contactor requirement in size S00. ## Integration notes Size S00 means a 45 mm width and 114 mm depth — fits standard 45 mm-wide DIN-rail slots. Side-by-side mounting is allowed, with a minimum 6 mm gap to adjacent devices for heat dissipation. For short-circuit protection, the manufacturer specifies a gL/gG fuse rated 20 A (type of coordination 2). That's the fuse size to order alongside the contactor if you need coordinated protection.","metaTitle":"Siemens 3RT1016-2EF04-0KS0-ZX95 SIRIUS Power Contactor, S00,","metaDescription":"Siemens 3RT1016-2EF04-0KS0-ZX95 SIRIUS power contactor, size S00, 24 VDC coil, spring-loaded terminals, rated 10 A at 24 V, 8.5 A AC-4 at 400 V.
