AC-4 reversing duty at 400 V is rated 8.5 A for high-inrush motor starts. Screw-type terminals on the main current circuit accept 2x (0.5–1.5 mm²) solid/stranded, 2x (0.75–2.5 mm²), or max 2x (0.75–4 mm²) — AWG equivalents: 2x (20–16), 2x (18–14), 1x 12. AC-1 / AC-12 resistive: 10 A at 24 V, 6 A at 230 V, 3 A at 400 V. AC-3 (not explicitly stated) is typically close to the AC-2 figure here. AC-4 reversing duty at 400 V is 8.5 A — this is the rating that governs high-inrush applications like plugging or jogging. Motor power at 690 V is 5.5 kW, at 500 V is 4.5 kW — these are the AC-2 / AC-3 class power ratings for a 3-phase induction motor on those voltage levels. Type 1 coordination (contactor may need replacement after fault) allows a 35 A gL/gG fuse. This matters when designing the upstream branch circuit for selectivity. ## Environmental limits Operating temperature -25 to +60 °C; maximum operating altitude 2 000 m without derating. Pollution degree 3 (conductive pollution typical in industrial enclosures).","metaTitle":"Siemens 3RT1016-1AK25-ZX95 SIRIUS S00 Contactor, 10A AC-12 a","metaDescription":"Siemens 3RT1016-1AK25-ZX95 SIRIUS S00 power contactor, 10 A AC-12 at 24 V, 4 kW AC-2 at 400 V.
