Product DescriptionThe SIEMENS 3RA29212A is a link module designed for S0-frame motor starters and contactors using spring-clamp terminal connections. This accessory creates a mechanical and electrical bridge between adjacent starter components in a multi-unit assembly, allowing grouped devices to share a common power feed without additional wiring between individual units. Electricians and industrial controls technicians install this module during panel builds or starter upgrades where space-saving, tool-less wiring is a priority. The spring-terminal design eliminates the need for screwdriver-tightened connections on the link interface itself.This link module is suited for use in industrial motor control centers, combination starter assemblies, and switchgear panels where S0-frame Siemens starters are grouped side by side. It is a common component in commercial and light industrial applications requiring organized, compact motor starter arrangements. Installation typically takes place during initial panel assembly or when expanding an existing row of S0-size starters.Key FeaturesSpring-clamp terminal interface for fast, reliable connections without conductor loosening over timeDesigned for S0-frame motor starter and contactor groupingsCompact form factor fits within standard panel layouts without additional clearance requirementsSingle-pack quantity suitable for individual starter pairs or incremental panel expansionLightweight construction at 0.201 pounds for easy handling during installationCompatibilityDesigned as an OEM-style link module accessory for S0-frame Siemens motor starters and contactors. Consult the specific starter series documentation to confirm fitment before installation.Installation NotesInstallation of this link module should be performed by a qualified electrician or industrial controls technician. De-energize and lock out the panel per NFPA 70E electrical safety procedures before handling any starter components. Verify that all devices in the assembly are rated for the same frame size before installing the link module. Do not force the module into position; proper alignment with S0-frame units should allow engagement without excessive pressure.Technical SpecificationsFrame Size: S0Terminal Type: Spring ClampLength: 4.134 inchesWidth: 2.756 inchesHeight: 1.772 inchesWeight: 0.201 poundsPackage Quantity: 1Standard InformationBrand: SIEMENSManufacturer Part Number: 3RA29212A
