DC switching ratings are more restrictive: at 48 V rated value the contacts handle 2 A, at 125 V rated value only 0.3 A — if you are switching DC solenoids or brake coils at 125 VDC, the 0.3 A ceiling limits the coil inrush you can break without contact welding. ## Temperature envelope and mechanical endurance The main contact rating is listed as 16 to 8 — this is the AC-3 utilization category current range in amperes at 400 V, meaning the contactor is sized for motor loads in the 8 to 16 A full-load current band at 400 VAC. ## Sourcing and lifecycle — current production, quoted to order Availability is confirmed at quote time against the BOM quantity; the part is sourced through authorized distribution channels and quoted to order.","metaTitle":"Siemens 3RT2326-1AP00-4AA0 SIRIUS Contactor, S0 Size, 45 mm","metaDescription":"Siemens 3RT2326-1AP00-4AA0 SIRIUS contactor, size S0, 45 mm width, 97 mm depth.
