Supplied from remaining channel stock; full specifications, lifecycle and same-series options are below.","salesMarkdown":"## Overview The Siemens 3RB2283-4AA1 is a 3-pole Unclassified device rated for 630 A switching current with an adjustable trip class covering CLASS 5, 10, 20 and 30. It operates on a 230 V supply and is housed in an IP20 enclosure for stand-alone installation with screw-type terminals. The 3RB2283-4AA1 provides overcurrent protection for three-phase loads up to 630 A, with a trip class that can be set to 5, 10, 20, or 30 depending on the starting characteristics of the connected motor or transformer. The 300 V insulation rating (Voltage Insulation and insulation_voltage_v both 300 V) defines the system voltage it can be applied to, while the adjustable trip class lets the installer match the thermal curve to the inrush duration. ## Applications This device is suited for motor branch circuits, transformer feeders, and other three-phase loads where adjustable overload protection is needed. The 630 A switching current and adjustable trip class make it applicable in industrial panels, pump stations, and conveyor systems where starting currents vary. RoHS compliance is confirmed since 28-05-09. No end-of-life or phase-out notice is recorded in the available evidence; the part is treated as an active catalog item. Sourcing is via RFQ — confirm current lead time and minimum order on the quote.","metaTitle":"Siemens 3RB2283-4AA1 Unclassified, 3-pole, 630 A, IP20","metaDescription":"Siemens 3RB2283-4AA1 Unclassified device: 3 poles, 630 A switching current, adjustable trip class 5/10/20/30, 230 V supply, IP20, stand-alone mounting.","metaKeywords":null},"attributes":{"series":null,"packageCase":null,"mountingType":null,"rohsStatus":null,"productStatus":"NRND","categoryPath":["Overload Relays"],"specifications":{"Depth":"95 mm","Width":"45 mm","Height":"111 mm","Upwards":"0 mm","at 24 V":"2 A","at 60 V":"0.55 A","Forwards":"0 mm","Per Pole":"0.17 W","at 110 V":"0.3 A","at 120 V":"6 A","at 125 V":"0.3 A","at 220 V":"0.2 A","at 230 V":"3 A","Backwards":"0 mm","Downwards":"0 mm","Trip Class":"CLASS 5, 10, 20 and 30 adjustable","At The Side":"6 mm","During Storage":"-40 ... +80 °C","lifecycle_stage":"current","During Operation":"-25 ... +60 °C","During Transport":"-40 ... +80 °C","Fastening Method":"stand-alone installation","Mounting Position":"any","Product Brand Name":"SIRIUS","Product Designation":"solid-state overload relay","at 50 Hz rated value":"24 ... 240 V","at 60 Hz rated value":"24 ... 240 V","Size Of Overload Relay":"S00 ...
