1STQ009387A0000 ABB PTBB7550 System pro E power IP40 Blind Top/Bottom Panel 750 x 500 mm

Why Choose the ABB PTBB7550 System pro E power IP40 Blind Top/Bottom Panel?

The ABB PTBB7550 is a purpose-designed IP40 blind top/bottom panel for the ABB System pro E power modular low-voltage switchboard range. This enclosure accessory provides a solid closure for compatible upper or lower switchboard openings, supporting organised enclosure construction and the intended protection arrangement of the completed electrical distribution assembly.

Designed for switchboard configurations with a specified 750 mm width and 500 mm depth, the PTBB7550 provides a dedicated top or bottom closure solution. Its IP40 designation identifies a protection arrangement intended to resist access by solid objects of 1 mm diameter or greater, without a specified level of water ingress protection.

Identified by ABB order code 1STQ009387A0000, the PTBB7550 carries the manufacturer designation IP40 BLIND TOP/BOTTOM W=750MM D=500MM. It is suitable for electrical panel builders, switchboard manufacturers and system integrators constructing compatible industrial and commercial low-voltage distribution assemblies.

IP40 Enclosure Protection and Blind Top/Bottom Closure

Top and bottom enclosure panels are important components in modular low-voltage switchboard construction. They close designated openings in the enclosure structure and help establish the physical boundary between the internal electrical equipment and the surrounding installation environment.

The ABB PTBB7550 provides a blind closure arrangement for compatible System pro E power switchboards with a specified 750 mm width and 500 mm depth. Its solid-panel configuration is intended for positions where an open cable-entry section or alternative equipment-specific cover is not required.

The IP40 designation is defined by the ingress protection classification system of IEC 60529. The first digit, 4, indicates protection against solid foreign objects with a diameter of 1 mm or greater and the corresponding level of protection against access to hazardous parts. The second digit, 0, indicates that no water ingress protection is specified.

Although the PTBB7550 is designated for an IP40 arrangement, the degree of protection achieved by the completed switchboard depends on the entire enclosure configuration, including adjacent panels, doors, joints, mounting accessories and installation quality. The panel alone does not establish the ingress protection rating of the assembled switchboard.

The wider ABB System pro E power platform supports modular low-voltage switchboard construction under the applicable requirements of IEC 61439-1 and IEC 61439-2. The PTBB7550 is a mechanical enclosure accessory and does not independently determine the current rating, short-circuit withstand capability or electrical compliance of the completed assembly.

For correct installation, the PTBB7550 should be matched to the intended switchboard dimensions and fitted according to the relevant ABB assembly documentation. Required fixing components and any additional enclosure protection accessories should be verified for the selected configuration.

Typical Applications

• ABB System pro E power modular low-voltage switchboards.
• Blind top-panel closure for compatible electrical distribution enclosures.
• Blind bottom-panel closure for compatible switchboard structures.
• Industrial main electrical distribution boards.
• Commercial building electrical distribution systems.
• Switchboard installations using 750 mm wide and 500 mm deep enclosure configurations.
• Indoor electrical distribution assemblies requiring an appropriate IP40 protection arrangement.
• Electrical panel manufacturing, assembly and compatible refurbishment projects.
