Control is via a 110-230 V AC coil, which means it pulls directly from a standard control transformer without needing a separate DC supply. Termination is spring-loaded (cage clamp), not screw — faster wiring in the panel, but verify your ferrule strip length against the terminal spec before terminating. The package dimensions are 105 x 27 x 122 mm, so it fits a standard DIN-rail footprint with a 27 mm width — roughly 1.5 standard module widths. Mount it with clearance for heat dissipation; solid-state contactors generate heat proportional to load current, and the 20 A AC-1 rating assumes 40 °C ambient with natural convection. If the panel runs hotter, derate accordingly.","metaTitle":"Siemens 3RF3320-2AA26 SIRIUS 3RF33 solid-state contactor, 20","metaDescription":"Siemens 3RF3320-2AA26 SIRIUS 3RF33 solid-state contactor, 1-pole, 20 A AC-1 at 40 °C, 48-600 V load, 110-230 V AC coil, spring-loaded terminals.
