2CPX066637R9999 ABB TR255100 2500 A TTA Corner Cabinet

Why Choose the ABB TR255100 2500 A TTA Corner Cabinet?

The ABB TR255100 2CPX066637R9999 is a high-current 2500 A corner cabinet designed for compatible ABB low-voltage power distribution and switchboard assemblies. Identified by ABB order number 66637, the TR255100 forms part of the ABB Streibel & John metalwork portfolio and provides a dedicated corner section for constructing non-linear switchboard layouts.

Designed for professional switchboard construction, the TR255100 enables a compatible distribution assembly to change direction at a corner rather than continuing exclusively in a straight line. This provides additional flexibility when designing high-current switchboards around switchroom dimensions, walls, structural features and other installation constraints.

The TR255100 is specified as a 2500 A TTA corner cabinet and belongs to ABB's coordinated family of 2500 A TTA incoming, coupler, changeover, outgoing and corner cabinet sections. Its system-specific design supports the creation of structured low-voltage distribution assemblies using compatible ABB cabinet, busbar and switchgear components.

Flexible 2500 A Corner Layouts for Low-Voltage Switchboards

Corner cabinets provide an effective way to construct low-voltage switchboard assemblies where the cabinet line-up needs to change direction. By incorporating a dedicated corner section, system designers can adapt a high-current distribution assembly to the geometry of the electrical room while maintaining a coordinated cabinet arrangement.

With its 2500 A rating, the ABB TR255100 is intended for demanding power distribution installations requiring both substantial current capacity and flexible switchboard positioning. It can form part of a compatible ABB TTA assembly alongside incoming, coupler, changeover and outgoing cabinet sections for industrial, commercial and infrastructure applications.

Typical Applications

• High-current low-voltage switchboards.
• Corner and non-linear switchboard configurations.
• Industrial power distribution systems.
• Switchrooms with space-constrained cabinet layouts.
• Commercial and infrastructure electrical distribution.
• Compatible ABB busbar and switchgear assemblies.
• Professional panel-building and switchboard projects.
