Siemens 3RT2015-2AK61-1AA0 — SIRIUS Power Contactor, Size S00 with Spring-Terminals
The spring-type terminals on the magnet coil and main contacts accept solid or stranded wire from 0.5 to 4 mm², including dual-wire entry up to 2x (0.5...4 mm²), which speeds panel wiring compared to screw-clamp variants. Rated operating current is 10 A at 24 V (AC-1 / AC-3 duty typical for this frame). The contactor includes an integrated auxiliary switch, eliminating the need for a separate add-on block for basic feedback or status signaling. Switching frequency limits are duty-dependent: up to 1,000 cycles/hour in AC-1 (resistive loads), 750 cycles/hour in AC-2 and AC-3 (motor starting/running), and 250 cycles/hour in AC-4 (plugging or inching). For AC-3e (enhanced motor rating) the limit is also 750 cycles/hour. These figures define the thermal capability of the contactor in continuous cycling applications — a line running frequent start/stop cycles should stay within the AC-3 or AC-3e ceiling.
The contactor is rated for standing vertical mounting on a horizontal surface. These ensure adequate airflow and arc-quenching space — tighten the panel layout to these minimums, not the DIN-rail edge. Dimensions are 73 mm depth, 45 mm width, and 70 mm height. The 45 mm width matches the standard S00 footprint, so it occupies four 11.25 mm DIN-rail positions (or one 45 mm wide slot in a modular enclosure).
Mechanical life of the contactor typical is 30,000,000 operations — this is the no-load mechanical endurance, not the electrical endurance under load. Electrical life depends on the switching duty and load current; for motor loads at rated current expect substantially fewer cycles, but the mechanical figure confirms the frame is built for high-cycle applications like conveyor or pump panels.
