Product details

Rating and load type

The 3RF3320-2AA06 is a 1-pole SIRIUS 3RF33 solid-state contactor rated 20 A in AC-1 duty (resistive load) at 40 °C ambient. That AC-1 figure governs switching of heaters, lighting banks, and transformer primaries — not motor starts. For inductive motor loads you derate to the AC-3 curve, which this part's datasheet defines separately; the 20 A AC-1 number is the ceiling for purely resistive circuits.

Control and termination

Coil is 24 V DC, so it drops into a standard 24 VDC control bus without an extra power supply rail. The load-side voltage range spans 48–600 V AC, covering 48 V, 120 V, 230 V, 277 V, 400 V, and 480 V line voltages without a tap change.

Frequently asked questions

What compliance documentation is available for this part?

RoHS compliant since 15 January 2024. REACH Article 33 declares lead (CAS 7439-92-1) above 0.1% w/w. No UL or CSA listing is recorded in the spec data.

What load types is the 20 A AC-1 rating suitable for?

The 20 A AC-1 rating applies to resistive loads — heaters, lighting, transformer primaries. For motor or inductive loads, consult the AC-3 derating curve in the full datasheet.
