GJI2322322R0003 ABB SZ-KS2/12 Single-Phase 24 mm² 207 mm Universal Comb Busbar

Why Choose the ABB SZ-KS2/12 Busbar?

The ABB SZ-KS2/12 is a universal single-phase comb busbar designed for efficient cross-wiring of compatible modular electrical devices in distribution boards and control panels. Supplied under ABB order code GJI2322322R0003, this insulated busbar provides a 24 mm² cross-section and an overall length of 207 mm.

The SZ-KS2/12 provides a practical alternative to individual wiring between compatible circuit protection devices, helping simplify panel assembly and create an organised electrical distribution system. Its single-phase configuration and standard 17.5 mm module pitch make it suitable for compatible modular installation equipment where a common electrical supply needs to be distributed across multiple devices.

With a rated continuous current of 100 A, maximum rated operational voltage of 400 V and rated short-time withstand current of 25 kA, the SZ-KS2/12 provides a robust solution for professional low-voltage distribution applications. The busbar is supplied without the touch-protection cover, with the compatible ABB SZ-BSA cover available separately where required.

Efficient Power Distribution for Modular Electrical Equipment

Comb busbars provide an efficient method of distributing a common electrical supply across compatible modular devices without requiring separate individual conductors between each connection. The ABB SZ-KS2/12 is designed for single-phase cross-wiring applications and combines a 24 mm² conductor cross-section with a compact 207 mm length.

Correct busbar selection depends on factors including terminal type, device pole configuration, equipment type, connection cross-section and the arrangement of devices within the installation. The SZ-KS2/12 provides a purpose-designed ABB solution for compatible low-voltage modular equipment, supporting efficient and organised distribution-board construction.
