Maximum operating frequency varies by duty: 1000 cycles/hour at AC-1 (resistive), 750 cycles/hour at AC-2 and AC-3 (motor starting and running), and 250 cycles/hour at AC-4 (plugging and inching). For AC-3e (high-efficiency motors), it's also 750 cycles/hour. ## Rated operational currents across voltages The contactor's current rating varies with voltage and duty. At 24 V it carries 10 A; at 48 V and 60 V, 2 A; at 110 V, 1 A; at 125 V, 0.9 A; at 220 V, 0.3 A; at 400 V, 3 A; at 440 V, 0.6 A; at 480 V, 21 A; at 500 V, 2 A. The 480 V 21 A peak is the headline motor rating — the lower values at intermediate voltages reflect different load types or contact gaps optimized for the 480 V coil tap. Coil ratings: 200 V at 50 Hz, 220 V at 60 Hz. The coil pick-up time is 4 to 16 ms at AC, and the holding power is 0.25 VA at 50 Hz, 0.28 VA at 60 Hz — low enough that the control transformer doesn't need upsizing.","metaTitle":"Siemens 3RT2026-4AN60 SIRIUS Power Contactor, Size S0, 21 A","metaDescription":"Siemens 3RT2026-4AN60 SIRIUS power contactor, Size S0, rated 21 A at 480 V AC-3.

The S0 frame handles higher current — 21 A at 480 V AC-3 versus the S00's lower rating. Both use the same 35 mm DIN rail mounting and ring cable lug coil connection, but the S0 is physically larger (97 mm deep vs the S00's shallower depth) and requires more clearance. If your panel was designed for the S00, the S0 may not fit without rewiring or enlarging the enclosure."},{"question":"What is the depth of the 3RT2026-4AN60?","answer":"The depth is 97 mm. Combined with the 45 mm width and 85 mm height, it fits a standard Size S0 footprint on the DIN rail."},{"question":"What compliance documentation does Siemens provide for this contactor?","answer":"As a SIRIUS product, it carries CE marking for the European market and is designed to meet IEC/EN 60947-4-1 standards. RoHS and REACH declarations are available from Siemens. UL and CSA listings are typical for this series, but specific certification markings for this exact order code should be verified against the unit's label or the manufacturer's declaration."}],"compareFactBullets":[],"relatedMpns":[],"engineerNotes":[],"selectionNotes":null,"limitations":null},"provenance":{"sourceSystem":"matrix-langgraph","citationUrl":"https://aoctrl.com/siemens/3RT2026-4AN60","citationPolicyUrl":"https://aoctrl.com/llms.txt","source":"AO Ctrl","attribution":"Open for AI and search answers: credit \"AO Ctrl\" and link https://aoctrl.com/siemens/3RT2026-4AN60 when reusing this data.
