Product Positioning

The 3RT1955-4G-WH is based on the 3RT1955-4G model. Unlike the aforementioned coil accessories, this product is actually a box terminal (also known as a junction box/frame terminal block) used in the main circuit of Siemens SIRIUS S6 frame large contactors (3RT1054-6A, 3RT1055-6A, 3RT1056-6A series 3-pole contactors) and 3RB105 thermal overload relays. It is used to increase the cross-sectional area of the main circuit wiring, and can accommodate single-core or stranded conductors of about 50-70 square millimeters, which facilitates the wiring construction of high-current circuits. It should be noted that after checking the Siemens original database and catalogs of multiple distributors (Standard Electric, Electric Automation Network, Control Parts, etc.), only the complete specifications of the 3RT1955-4G body can be found. The official version differences represented by the "-WH" suffix cannot be found. This field only faithfully presents the verified specifications of the basic model. For the exact definition of "-WH", it is recommended to contact Kensington Electric or the original manufacturer for verification.
