That AC-1 rating is the key number for heater, lighting, or resistive oven loads — it tells you the continuous current the SSR can carry without a heatsink derate at that temperature. The load voltage range is 48-600 V AC, and the control coil is 24 V DC, which is standard for industrial PLC or relay outputs. Blocking voltage is 1600 V, giving headroom for transient spikes on 480 V lines. ## Short-circuit coordination and protection This contactor is specified as short-circuit proof up to 25 A when paired with a B-curve miniature circuit breaker. That means you can size the upstream MCB at 25 A type B and the SSR will survive a fault without welding its output — useful for panel builders who want to avoid fuses and keep DIN-rail coordination simple. The screw terminals accept standard ring or fork lugs, so no special crimp tool needed on site. Packaging dimensions are 105 x 27 x 122 mm — a slim 27 mm wide footprint that clips onto a standard DIN rail. The 1-pole design means it switches one phase; for three-phase resistive loads you'd use three units or step up to a 3-pole 3RF34 variant.","metaTitle":"3RF3330-1DA06 SIRIUS solid-state contactor, 30 A AC-1, 24 VD","metaDescription":"Active SIRIUS 3RF33 1-pole solid-state contactor. 30 A AC-1 at 40 °C, 48-600 V load, 24 VDC control.
