The coil is rated 24 VDC, drawing 6 A at that rated value — a key figure for sizing the control transformer or DC power supply feeding the panel. Main contact termination uses spring-type terminals, accepting solid or stranded wire from 1 to 10 mm², with dual-wire capacity for 2x (0.5 to 2.5 mm²). This speeds wiring compared to screw clamps, especially on repetitive builds.
Switching frequency is rated at 1,000 operating cycles per hour for AC-1, AC-2, AC-3, and AC-3e duty, dropping to 300 cycles per hour for AC-4. For high-cycling applications like rapid reversing or jogging, the AC-4 limit is the binding constraint. Mechanical life is typical 10,000,000 operations — the contactor itself will outlast most application cycles if the electrical load stays within the rated utilization category. This helps when the DIN rail is oriented unusually or the panel layout is tight.
Clearance and Wiring Details
Physical dimensions: 102 mm height, 45 mm width, 154 mm depth. These are the minimum air gaps for heat dissipation and arc containment; crowding the contactor against cable ducts or other devices risks derating. Arcing time is 10 to 10 ms — a tight band, meaning the arc extinguishes quickly, which helps with contact life and reduces EMI in the panel. This variant has no auxiliary switch block (Auxiliary Switch: No). If your circuit needs feedback or status signaling, you will need to add a separate auxiliary contact block that fits the S0 frame.
The paperwork — CE, RoHS, REACH, and manufacturer declarations — is standard for a Siemens SIRIUS contactor and can be provided with the shipment.
