Why Choose the ABB SZPSB51N SZ-PSB51N Busbar?
The ABB SZPSB51N, manufacturer type SZ-PSB 51 N, is a three-phase busbar block designed for distributing power across compatible ABB modular circuit protection devices. Part of ABB's System pro M busbar system, it provides a purpose-designed method of cross-wiring multiple devices while reducing the need for individual interconnecting conductors.
The SZ-PSB 51 N features a 3 × 3 arrangement providing 9 connection poles and a substantial 16 mm² conductor cross-section. ABB specifies this version for three-pole miniature circuit breakers with an auxiliary switch supplied from three phases, making it particularly useful where coordinated multiphase distribution is required within a compact modular assembly.
At approximately 176 mm long, the SZ-PSB 51 N provides a compact solution for three-phase power distribution. Its shock-protected busbar-block construction incorporates combined box terminals, eliminating the need for separate connection terminals, while ABB identifies this specific version with order code GHV0360874R0029.

Reliable Three-Phase Distribution for Modular Protection
Busbar blocks provide an efficient method of distributing a common electrical supply between adjacent modular protection devices. By replacing multiple individual jumper conductors with a purpose-designed conductive assembly, they can simplify panel wiring, improve connection consistency and help maintain an organised electrical distribution layout.
The ABB SZ-PSB 51 N combines a 16 mm² cross-section with a compact 3 × 3 connection arrangement for three-phase applications. Its shock-protected construction and combined box terminals make it a practical ABB System pro M accessory for professional installations using compatible three-pole circuit breakers and auxiliary switching equipment.
Typical Applications
- Three-phase electrical distribution boards.
- Three-pole miniature circuit breaker assemblies.
- MCB installations incorporating auxiliary switches.
- Industrial control panels.
- Commercial electrical switchboards.
- Machine control cabinets.
- Compact modular protection assemblies requiring a common three-phase supply.
