Why Choose the ABB SZ-PSB56N Busbar?
The ABB SZ-PSB56N is an insulated two-phase phase busbar designed for safe and economical cross-wiring of compatible miniature circuit breakers, residual current protection devices and other modular installation equipment. Identified by ABB order code GHV0360874R0034, it forms part of ABB’s MCB accessories range for professional low-voltage distribution systems.
The SZ-PSB56N features 58 connection poles / pins in a two-phase arrangement, providing connections for up to 29 compatible devices. Its 16 mm² conductor cross-section, 17.5 mm pitch and 1035 mm length make it particularly suitable for larger modular distribution boards requiring extensive two-phase or phase-and-neutral cross-connection.
With a rated continuous current of 80 A, maximum rated operational voltage of 690 V and rated short-time withstand current of 25 kA, the SZ-PSB56N provides a robust alternative to extensive individual cross-wiring. Its insulated construction and pin-type connections help simplify installation while maintaining a consistent and organised panel layout.

Efficient Two-Phase and Phase-Neutral Distribution
Phase busbars provide an efficient method of cross-wiring multiple compatible modular protection devices without requiring individual conductors between every terminal. This can significantly reduce wiring effort in larger assemblies while improving connection consistency and helping installers maintain a clean, organised distribution-board layout.
The ABB SZ-PSB56N combines 58 connection points with a 16 mm² conductor cross-section and an 80 A continuous-current rating. Its two-phase configuration is also suitable for compatible equipment with a neutral conductor, making it useful for extensive phase-and-neutral distribution arrangements containing up to 29 modular devices.
Typical Applications
- Two-phase electrical distribution assemblies.
- Phase-and-neutral modular protection circuits.
- Miniature circuit breaker installations.
- Residual current protection installations.
- Commercial and industrial distribution boards.
- Professional switchgear and panel-building applications.
