Product details

The Siemens 3RF3330-1AA45 is a 1-pole solid-state contactor from the SIRIUS 3RF33 family, rated for 30 A in AC-1 duty at 40 °C ambient. AC-1 is the resistive load rating — heaters, ovens, lighting banks, not motor starts. The 1200 V blocking voltage gives headroom for 480 V line transients without avalanche failure. Control input accepts 4-30 V DC, so it plays nicely with 24 V PLC outputs or 5 V logic without a level shifter.

Screw terminals for the power and control wiring — no special crimp tool needed, just a #2 Pozidriv. The 48-600 V operating range covers 120 V to 480 V common line voltages.

Frequently asked questions

What compliance documentation is available for this part?

RoHS compliant since 15-Jan-2024. REACH Article 33 declares lead (CAS 7439-92-1) above 0.1% w/w. The manufacturer provides a Declaration of Conformity and material declaration upon request.

What are the key electrical ratings for the 3RF3330-1AA45?

30 A AC-1 resistive load at 40 °C ambient, 48-600 V operating voltage, 1200 V blocking voltage. Control input is 4-30 V DC. Screw terminals for both power and control wiring.
