Product details

The Siemens 3RF3330-1AA25 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated for 30 A in AC-1 (resistive) duty at 40 °C. 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.

Frequently asked questions

What is the AC-1 rating and what does it mean for my application?

The AC-1 rating is 30 A at 40 °C, which applies to resistive loads. 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.

What control voltage does this contactor need?

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.

Does this part have RoHS or REACH compliance documentation?

RoHS compliant since 15 January 2024. REACH Article 33 applies — the product contains lead above 0.1% w/w (CAS 7439-92-1). No UL or IEC certification is listed in the available documentation.
