Siemens 3RT1955-4G High Current Terminal Block with a Maximum Connection Capacity of 70mm²

Product Positioning

The 3RT1955-4G is a high-current terminal block used in Siemens SIRIUS large contactor series (S6 frame). Also known as a frame terminal block or junction box, its main function is to replace standard screw terminals, allowing high-current contactors such as the 3RT1054 and 3RT1055 to connect thicker wires or copper busbars, meeting the wiring requirements of high-load motor control circuits. This accessory is an original equipment manufacturer (OEM) part, not the complete contactor body. It is suitable for contactor replacement and maintenance, expanding wiring capacity, or when used in conjunction with overload protection and soft starters to form a complete motor control unit.

Core Product Advantages and Features

High current wiring design

The terminal block can accommodate single-core or stranded conductors up to 70mm², or AWG 2x1/0 cables, meeting the high-current wiring requirements of S6 frame contactors for thick conductors.

Made in Germany

The product is made in Germany and comes with EAN barcode 4011209512450. It is guaranteed to be completely compatible with the 3RT1054/3RT1055 contactor body and fit tightly during installation.

Diverse and compatible combinations

It can be assembled with the 3RB105 series overload protection relay, 3RW443 soft starter and 3UF71.3-1BA00-0 monitoring module to expand the flexibility of the control system.

Complete certification

It has multiple international safety certifications such as UL, EAC, and RCM, as well as EU declaration of conformity, and is suitable for export or multinational equipment wiring needs.
