{"schemaVersion":"matrix-product-facts/v1","identity":{"mpn":"3RA2324-8XE30-2BB4","brand":"Siemens","brandSlug":"siemens","productSlug":"3RA2324-8XE30-2BB4","canonicalUrl":"https://aoctrl.com/siemens/3RA2324-8XE30-2BB4","factsUrl":"https://aoctrl.com/api/mcp/products/3RA2324-8XE30-2BB4","rawCanonicalId":null},"summary":{"shortDescription":"Siemens SIRIUS 3RA2324-8XE30-2BB4 reversing contactor assembly, S0 frame, 5.5 kW at 400 V AC-3, 11 A at 480 V, spring-loaded terminals, 90 x 114 x 107 mm.","salesMarkdown":"## Supplied as a ready-to-wire reversing pair The 3RA2324-8XE30-2BB4: This SIRIUS reversing contactor assembly ships with two S0 contactors — a 3RT2024-2BB40 and a 3RT2024-2BB40-0CC0 — plus the mechanical interlock kit 3RA2923-2AA2 already fitted. That means it arrives as a single order code, pre-assembled for forward/reverse motor control, rather than you sourcing and interlocking two separate contactors and the RH kit. ## Motor ratings that decide the fit The AC-4 rating at 400 V is also 5.5 kW, which covers plugging and inching duty where the contactor opens under full locked-rotor current. Mechanical endurance is 10 million operating cycles typical for the S0 contactor frame. That is relevant for high-cycle applications like conveyor reversers or pump run-down timers — the contactor itself will outlast most panel rebuild intervals before the mechanism wears. ## Panel integration and terminal constraints The assembly measures 90 mm wide by 114 mm high by 107 mm deep — the S0 frame footprint. Clearances: 6 mm upwards, forwards, downwards, and to the side; zero clearance needed backwards. That means it fits tightly against the back panel without a ventilation gap. Both the main current circuit and the auxiliary/control circuit use spring-loaded terminals. No screw-torque check needed — push the ferrule or stripped wire in and the cage clamps it. This saves time on repetitive builds and eliminates the risk of a loose screw vibrating out. ## Shock and temperature — what the numbers mean for reliability The assembly is rated for 11.8 g at 5 ms and 7.4 g at 10 ms under AC shock, and 15 g at 5 ms / 10 g at 10 ms under DC shock. That is the half-sine pulse it can survive without the contacts bouncing or the interlock disengaging — relevant if the panel is on a mobile platform or near a press that transmits vibration through the floor.","metaTitle":"Siemens 3RA2324-8XE30-2BB4 SIRIUS Reversing Contactor","metaDescription":"Siemens 3RA2324-8XE30-2BB4 SIRIUS reversing contactor assembly, S0 size, 5.5 kW at 400 V AC-3.
