S0 frame size: 45 mm width, 102 mm height, 144 mm depth. That covers most industrial environments short of direct oven-side mounting. ## Duty-cycle and switching frequency Switching frequency varies by duty class: AC-1 (resistive) allows up to 1,000 operations per hour, AC-2 and AC-3 (motor starting/running) both allow 750 ops/h, and AC-4 (plugging/inching) drops to 250 ops/h. The AC-3e rating also sits at 750 ops/h. These numbers govern thermal rise in the coil and contacts — exceed them and you'll accelerate wear or cause nuisance tripping. Arcing time is 10 to 10 ms (tight window), and the at-AC switching time is 4 to 16 ms. That's typical for a contactor this size — fast enough for most motor control circuits, but if you're timing a sequence with millisecond precision, account for the spread. ## Auxiliary contact ratings and clearance This variant ships without an auxiliary switch block (Auxiliary Switch: No). If you need aux contacts for status feedback or interlocking, you'll add a separate side-mount block. The auxiliary contact breaking capacity is rated at specific voltages: 6 A at 24 V, 2 A at 48 V and 60 V, 1 A at 110 V, 0.9 A at 125 V, 0.3 A at 220 V, and 0.6 A at 440 V. At 230 V it's rated 3 hp, and at 400 V it's 3 A. These are the free-air gaps needed for heat dissipation and arc containment — don't crowd the contactor tighter than that in a dense panel.","metaTitle":"Siemens 3RT2026-2AN24 SIRIUS S0 Power Contactor, 24 VDC Coil","metaDescription":"Siemens 3RT2026-2AN24 SIRIUS S0 power contactor. 24 VDC coil, spring-type terminals.
