1STQ001576B0000 ABB PSHW4072 System pro E Power Form 3b Horizontal Segregation E2.2 3P 400 x 700 mm

Why Choose the ABB PSHW4072 Horizontal Segregation Accessory?

The ABB PSHW4072 is a dedicated horizontal segregation accessory for compatible ABB System pro E power low-voltage switchboard assemblies. Designed for an ABB E2.2 3-pole circuit-breaker arrangement, it is specified for a cabinet configuration measuring 400 mm wide × 700 mm deep, with a manufacturer-designated Form 3b (F3B) segregation arrangement.

Internal segregation is an important consideration in low-voltage switchboard design, particularly where functional units, busbars and associated terminals require defined separation. The PSHW4072 supports the implementation of the specified horizontal segregation arrangement within compatible System pro E power switchboards incorporating ABB E2.2 circuit-breaker equipment.

Identified by ABB order code 1STQ001576B0000 and the manufacturer designation HORIZ.SEG.F3B 3P W E2.2 W=400MM D=700MM, the PSHW4072 is intended for professional switchgear manufacturers, electrical panel builders and engineers assembling compatible ABB low-voltage power distribution systems.

Understanding Form 3b Horizontal Segregation

Form 3b is an internal separation arrangement used in low-voltage switchboard assemblies. Under the applicable IEC 61439 separation framework, Form 3 arrangements distinguish the busbars from functional units and separate functional units from one another. Form 3b additionally addresses the separation of terminals for external conductors from the busbars.

The ABB PSHW4072 is designated as a horizontal segregation component for Form 3b. It forms part of the mechanical arrangement used to establish the intended separation within a compatible System pro E power assembly.

Horizontal segregation components can be used to define separation boundaries between designated areas of a switchboard. Their correct selection depends on the enclosure dimensions, installed protective equipment, compartment layout and the overall segregation design.

For the PSHW4072, ABB specifies an E2.2 3-pole configuration with a nominal cabinet width of 400 mm and depth of 700 mm. These parameters should be matched against the planned switchboard configuration before ordering or installation.

The PSHW4072 is an individual segregation accessory. Its use alone does not establish that a complete switchboard achieves Form 3b separation; the required overall arrangement must be assembled and verified using the appropriate compatible components and manufacturer instructions.

Integration with ABB E2.2 Circuit-Breaker Assemblies

The ABB E2.2 frame belongs to the ABB Emax 2 air circuit-breaker family, used in low-voltage power distribution and switching applications. These devices may be incorporated into modular switchboards where the mechanical layout and internal separation arrangements must be coordinated with the selected equipment.

The PSHW4072 is specifically identified for a 3-pole E2.2 installation. Its manufacturer designation should not be interpreted as confirmation of compatibility with 4-pole E2.2 breakers or other ABB circuit-breaker frames.

When designing a System pro E power switchboard, panel builders should coordinate segregation accessories with the circuit-breaker installation arrangement, busbar system, terminal locations and other required internal partitions.

The completed assembly must be assessed against the applicable switchboard design requirements, including clearances, access arrangements, thermal performance, dielectric properties and the intended internal separation classification.
