Siemens 3RA1912-2H Contactor Accessory

Product Description

The SIEMENS 3RA1912-2H is a contactor accessory designed to expand or complete the functionality of compatible SIEMENS contactor assemblies. Contactor accessories in this class typically serve as add-on components such as auxiliary contact blocks, mechanical interlocks, or mounting bridges that integrate directly with the base contactor unit. Installation is performed by licensed electricians working on motor control centers, panel boards, or industrial control enclosures. The compact form factor of the 3RA1912-2H allows it to fit in tight assembly configurations without sacrificing reliable electrical performance.

This accessory is suited for use in commercial and industrial electrical installations where SIEMENS 3RA-series contactors are deployed. Typical applications include motor starters, reversing contactor assemblies, and control panel builds in manufacturing, HVAC, and process control environments. The small package size makes it appropriate for dense panel layouts where space constraints are a primary concern.

Installation Notes

Installation should be performed by a licensed electrician in accordance with the National Electrical Code (NEC) and any applicable local codes. De-energize and lock out the panel or motor control center before servicing or installing contactor accessories. Follow SIEMENS installation documentation for proper mounting orientation and securing of the accessory to the base contactor.
