1STQ001574B0000 ABB PSHF4072 Form 3b Horizontal Segregation 3P Fixed E2.2 400 x 700 mm

Why Choose the ABB PSHF4072 Horizontal Segregation Kit for E2.2 Circuit Breakers?

The ABB PSHF4072 (1STQ001574B0000) is a dedicated Form 3b horizontal segregation accessory designed for compatible ABB E2.2 circuit breaker installations within low-voltage electrical distribution switchboards. As part of the ABB System pro E power range, this component supports the construction of compartmentalised switchboard assemblies requiring defined internal separation between electrical equipment and functional units.

The PSHF4072 is specifically intended for 3-pole fixed E2.2 circuit breaker configurations in switchboards designed with Form 3b internal separation. Its application-specific construction helps electrical panel builders establish the required horizontal segregation arrangement within compatible assemblies, supporting organised equipment layouts and the separation of designated switchboard compartments.

Designed for a 400 mm nominal switchboard width and 700 mm nominal depth, the PSHF4072 provides a dedicated horizontal segregation solution for compatible ABB System pro E power installations. It is particularly suitable for industrial and commercial power distribution assemblies incorporating ABB Emax 2 E2.2 air circuit breakers.

Reliable Form 3b Internal Segregation for Electrical Distribution Switchboards

Internal segregation is an important design consideration in low-voltage switchboard construction. Under the principles of BS EN IEC 61439-2, Form 3 internal separation provides separation of busbars from functional units and separation between functional units. In a Form 3b arrangement, terminals for external conductors are also separated from the busbars, while terminals associated with different functional units are not necessarily separated from one another.

The ABB PSHF4072 supports the horizontal segregation arrangement required for compatible 3-pole fixed Emax 2 E2.2 circuit breaker installations within ABB System pro E power switchboards. It is designed for assemblies with a nominal width of 400 mm and depth of 700 mm, helping panel builders implement the intended internal compartment layout.

The ABB System pro E power range provides a modular platform for constructing low-voltage electrical distribution assemblies with different equipment configurations and internal separation requirements. The PSHF4072 forms part of this coordinated installation system and must be used with the appropriate compatible segregation panels, structural components and mounting accessories. The required Form 3b classification depends on the design and verification of the complete switchboard assembly rather than on any individual segregation accessory.

Typical Applications

• ABB System pro E power Form 3b low-voltage switchboards.
• ABB Emax 2 E2.2 fixed 3-pole circuit breaker installations.
• Industrial main electrical distribution boards.
• Commercial building low-voltage power distribution assemblies.
• Compartmentalised switchgear and electrical distribution cabinets.
• Horizontal separation arrangements within compatible switchboard structures.
• Electrical panel building and switchgear manufacturing projects.
• Power distribution assemblies requiring coordinated internal segregation.
