That means it fits into tight retrofit enclosures where the rail orientation is already set. ## Physical fit and clearance Dimensions are 97 mm deep, 45 mm wide, 102 mm tall — the S0 footprint. If you're squeezing it into an existing panel, those are the minimum air gaps for heat dissipation and arc containment. The coil connection uses spring-type terminals — no screw tightening there, which saves a few seconds per wire on a multi-contactor panel build. ## Duty cycle and endurance Mechanical endurance is 10 million operations typical — that's the contactor's life before the armature wears out, not the contacts. Switching frequency at AC-3 duty (motor switching) is 1,000 operations per hour maximum; at AC-4 (plugging/reversing) it drops to 300 per hour. If your application cycles faster than that, the contactor overheats internally. The arcing time is a tight 10 ms, and the operating time at AC is 4 to 16 ms — fast enough for most motor starter coordination schemes. ## Auxiliary contact ratings An auxiliary switch is included. These are the make/break capacities for the auxiliary contacts — use them to size your PLC input or relay coil draw.","metaTitle":"Siemens 3RT2025-2AK60-ZW96 SIRIUS Contactor, S0 Frame, 3 hp","metaDescription":"Siemens 3RT2025-2AK60-ZW96 SIRIUS power contactor, S0 frame, 3 hp at 230 V, 97 mm depth.
