1STQ001268B0000 ABB PTBB2530 IP40 Blind Top/Bottom Panel 250 × 300 mm

Why Choose the ABB PTBB2530 IP40 Blind Top/Bottom Panel?

The ABB PTBB2530 IP40 Blind Top/Bottom Panel, manufacturer order code 1STQ001268B0000, is a dedicated solid enclosure covering accessory from the ABB System pro E power range. Designed for compatible low-voltage switchgear assemblies, this component provides a blind top or bottom covering arrangement for an enclosure with a nominal width of 250 mm and depth of 300 mm.

Top and bottom enclosure panels are essential elements of modular electrical switchboard construction. They help close designated enclosure sections, maintain the intended mechanical arrangement and contribute to the protection of internal electrical equipment. The ABB PTBB2530 features a blind, non-aerated configuration, making it appropriate for compatible installations where a closed panel is specified instead of a ventilated covering.

With an IP40 protection designation, the PTBB2530 supports System pro E power enclosure arrangements designed to restrict access by specified solid foreign objects. Its dedicated 250 × 300 mm width-and-depth configuration enables accurate selection for corresponding ABB switchboard assemblies, while the manufacturer reference 1STQ001268B0000 simplifies identification, procurement and replacement.

Reliable Top and Bottom Enclosure Closure for System pro E Power Switchboards

Industrial low-voltage switchgear assemblies require carefully selected enclosure components to maintain their intended mechanical construction and provide appropriate separation between internal electrical equipment and the surrounding environment. Top and bottom covering panels are important parts of this arrangement, closing designated cabinet sections and contributing to the completed enclosure structure.

The ABB PTBB2530 IP40 Blind Top/Bottom Panel is designed for corresponding System pro E power enclosure arrangements with a nominal width of 250 mm and depth of 300 mm. Its blind construction provides a covering arrangement without intentional ventilation openings, distinguishing it from aerated enclosure panels used where airflow is required.

The IP40 classification, defined by IEC/EN 60529, indicates protection against solid foreign objects with a diameter of 1 mm or greater. The second digit, zero, indicates that no degree of protection against water ingress is specified. This distinction is important when determining whether the completed switchboard is suitable for its intended installation environment.

Because the PTBB2530 is a blind panel, it should be selected as part of the switchboard's overall thermal management design. Electrical loading, internal component heat generation, ventilation arrangements and permissible temperature rise must be considered for the complete assembly. A blind top or bottom covering should not be substituted for an aerated component without checking the manufacturer's configuration requirements.

Correct installation requires the appropriate System pro E power enclosure arrangement and specified fixing components. The final ingress protection performance depends on the complete assembly, including doors, panels, joints, cable entries and other accessories. Installing the PTBB2530 alone does not establish an IP40 rating for the entire switchboard.
