Siemens 3RT1955-4G Terminal Lug

Siemens 3RT1955-4G is a box terminal lug that serves as a dedicated termination accessory for the SIRIUS 3RT1054 size S6 contactor. In motor-control panels and switchgear assemblies, this lug provides a stable connection point for power conductors that feed the contactor, supporting clean, compact wiring within a Sirius-frame installation. The lug is specified for conductors up to approximately 70 mm² in cross-section, enabling larger-diameter cables typical of medium- to high-current feeder runs. The 3RT1955-4G is listed by Siemens Industry Mall as a box terminal for the 3RT1054/S6 configuration, reinforcing its role as a purpose-built accessory within the Sirius system. It is designed to integrate with the standard Sirius frame mounting footprint of the 3RT1054, helping to maintain consistent installation dimensions and alignment with adjacent accessories. Part of the Siemens Sirius line, this lug ships as a factory accessory and is intended for use in professional electrical installations.
