The power circuit handles 48-600 V AC, and the coil is wound for 110-230 V AC — a dual-range control voltage that simplifies panel wiring across common line voltages without a separate transformer tap. The 1-pole configuration is intended for single-phase resistive loads — heaters, ovens, lighting banks — where zero-crossing switching minimizes electrical noise and contact wear. The 3RF3310-2AA26 carries an active lifecycle status from Siemens. It is a current-catalog product, not subject to phase-out or last-time-buy. No cross-reference or successor part exists because none is needed; this is the current production variant. RoHS compliance is confirmed effective 15 January 2024, with a REACH Article 33 disclosure for lead (CAS 7439-92-1 > 0.1% w/w) in the current candidate list. ## What the key rating means for fit The AC-1 rating of 10 A at 40 °C is the resistive-load current limit — it is not a motor-switching figure. AC-1 covers resistive heating elements, incandescent lighting, and transformer primary switching where inrush is modest. If the load is inductive (motors, solenoids, contactor coils), the AC-3 or AC-15 duty rating would be lower; this part is specified only for AC-1 duty, so match it to the load type, not the nameplate current. The 48-600 V operating range covers standard low-voltage single-phase supplies worldwide. The 97 x 27 x 105 mm envelope (L x W x H) fits a standard DIN-rail footprint, with spring-clamp terminals accessible without removing the unit from the rail. The 27 mm width occupies one modular spacing unit, leaving room alongside a matching 3RF34 three-pole unit if three-phase resistive switching is later required. The 110-230 V AC coil range means the control transformer secondary can be tapped at either common voltage without rewiring.","metaTitle":"Siemens 3RF3310-2AA26 SIRIUS solid-state contactor, 1-pole,","metaDescription":"Siemens 3RF3310-2AA26 SIRIUS 3RF33 solid-state contactor, 1-pole, AC-1 10 A at 40 °C, 48-600 V, 110-230 V AC coil, spring-loaded terminals.
