That AC-1 rating means it's sized for switching resistive loads like heaters or lighting banks — not motor starts, which would need the AC-3 derating curve. The operating voltage range spans 48-600 V, with a 110-230 V AC control supply. Blocking voltage is 1200 V, giving semiconductor headroom for line transients on a 480 V or 600 V system. This is a DIN-rail mount part, sized for a standard control panel enclosure. The screw terminal connection matches conventional wiring practices — no special tooling needed. At 105 x 27 x 122 mm, it occupies a single module width, so it slots into a crowded rail without stealing space from adjacent breakers or relays. ## Compliance and regulatory posture RoHS compliant since 15 January 2024.","metaTitle":"Siemens 3RF3330-1AA25 SIRIUS 3RF33 Solid-State Contactor, 30","metaDescription":"Siemens 3RF3330-1AA25 SIRIUS 3RF33 1-pole solid-state contactor, 30 A AC-1 at 40 °C, 48-600 V, 110-230 V AC screw terminal.

For motor loads (AC-3 duty), you'd need to derate — typically to about 1/3 of the AC-1 current. This part is best suited for heater banks, lighting contactor duty, or other resistive switching where inrush is minimal."},{"question":"What control voltage does this contactor need?","answer":"The control supply is 110-230 V AC. That's a wide-range coil, so it works on either 120 V or 208-240 V control circuits common in North American and European panels."},{"question":"Does this part have RoHS or REACH compliance documentation?","answer":"RoHS compliant since 15 January 2024.
