The 3RT2016-2AP01 is a Size S00 SIRIUS power contactor — the smallest frame in the family, at 45 mm wide, 70 mm tall, and 73 mm deep. That footprint fits standard 45 mm-wide DIN-rail slots; you can pack multiple units side by side without oversizing the enclosure. These are the air-gap and creepage distances for the rated voltage — respect them to avoid flashover between adjacent devices.
Wire termination and coil connection
The coil connection uses spring-type terminals — push-in for solid or ferruled stranded, no screw tightening needed.
Switching duty and mechanical life
Maximum switching rates: 1,000 operations per hour in AC-1 (resistive), 750 ops/h in AC-3 and AC-3e (motor starting), and 250 ops/h in AC-4 (plugging/inching). These are the thermal limits of the contactor — exceeding them shortens contact life or causes welding. An auxiliary switch is built in, with main contact configuration options between 20 and 12 (likely NO/NC combinations). Confirm the exact auxiliary contact arrangement from the full datasheet before wiring.
Environmental limits and lifecycle
The contactor is rated for indoor use in a typical control panel environment.
