At 73 mm deep, 70 mm tall, and 45 mm wide, it fits the standard S00 footprint — a common size for compact auxiliary and coupling duties in motor control centers. The DC switching ratings tell you what loads this contactor can break: 10 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 3 A at 400 V. These are the current limits for DC-1 and DC-3 duty — use them to size the contactor for solenoid valves, DC brakes, or signal isolation. Switching frequency: up to 1,000 cycles/hour at AC-1, 750 at AC-2 and AC-3, and 250 at AC-4. Wire range: 0.5 to 4 mm² solid or stranded, 2x (0.5–4 mm²) per terminal. Spring-type terminals. Clearances: 10 mm upwards, downwards, and forwards; 6 mm at the sides.","metaTitle":"Siemens 3RT2016-2KB42-ZX95 SIRIUS Coupling Contactor, Size S","metaDescription":"Siemens SIRIUS coupling contactor 3RT2016-2KB42-ZX95, Size S00, 24 V DC coil, spring-type terminals, 45 mm wide.
