Why Choose the ABB ZH217 440 A 30 × 5 mm Busbar System?
The ABB ZH217, order code 2CPX060446R9999, is a high-capacity 3-pole copper busbar system designed for ABB CombiLine N electrical distribution assemblies. As part of ABB’s DESUJ Sub Distribution product group, it provides a reliable power distribution solution for NH1/NH2 fuse-switch disconnector modules and professional low-voltage distribution systems.
Rated for a current of 440 A, the ZH217 uses 30 × 5 mm copper busbars arranged in a single-level, 3-pole configuration. The system incorporates M10 connection screws and is intended for use with the ABB M(B)T244 module configuration, providing a purpose-designed interface for high-current distribution equipment.
The ZH217 has a busbar spacing of 57 mm and a short-time withstand current (Icw) of 25 kA. Its copper conductors, robust construction and dedicated CombiLine N compatibility make it suitable for demanding commercial and industrial sub-distribution applications where dependable high-current power distribution is required.
