The Siemens 3RF2310-1AA24 is a SIRIUS-brand single-phase solid-state contactor rated 10.5 A in AC-51 duty (resistive loads) and 9.6 A per UL 508. It switches loads from 48 to 460 VAC at 50/60 Hz, with zero-point switching to reduce inrush and EMI on heater or lamp banks. The control circuit accepts 110-230 VAC and draws 15 mA — a standard signal for most PLC or relay outputs.
Width is 22.5 mm — one standard module slot. Main circuit terminals accept 1.5-6 mm² stranded or 2x (14-10) AWG; control terminals take 0.5-2.5 mm² solid or 2x 0.5-1.0 mm². Side-by-side mounting is allowed with no derating up to 40 °C.
