Why Choose the ABB TZ434 Centre Support Rail?
The ABB TZ434 is a robust centre support rail for ABB TwinLine electrical cabinets, designed to provide additional internal mounting support within compatible enclosure systems. With a 4 PW field width of 1000 mm, it is intended for professional distribution-board and switchgear installations requiring a secure central support structure.
As part of the ABB TwinLine enclosure system, the TZ434 is supplied as an unmounted kit for installation within compatible wall-mounted and floor-standing cabinets. The support rail uses a galvanised steel C-profile construction and screw mounting, providing a durable mechanical foundation for organised internal cabinet assemblies.
The TZ434 has nominal dimensions of approximately 994 mm wide × 30 mm high × 40 mm deep. Two additional mounting strips are required for installation, selected from TZ601, TZ602 or TZ603 according to the cabinet depth. ABB order code 2CPX010963R9999 provides precise identification for specification, procurement and replacement.
