1STQ007109A0000 ABB PTBB3050 System pro E power IP40 Blind Top/Bottom Panel W300 D500

Why Choose the ABB PTBB3050 System pro E power IP40 Blind Top/Bottom Panel?

The ABB PTBB3050 (1STQ007109A0000) is a dedicated IP40 blind top/bottom enclosure panel designed for compatible ABB System pro E power low-voltage electrical switchboard assemblies. Specified for a 300 mm nominal enclosure width and 500 mm nominal depth, this accessory provides a closed panel arrangement for the upper or lower section of a matching electrical distribution cabinet.

As part of the ABB System pro E power modular switchboard range, the PTBB3050 supports the construction of organised electrical distribution enclosures requiring an IP40-designated protective configuration. Its blind design provides a closed surface without dedicated cable-entry or ventilation openings, helping complete the cabinet's physical enclosure boundary.

The ABB PTBB3050 is particularly suitable for electrical panel builders, switchboard manufacturers and industrial contractors constructing 300 mm wide × 500 mm deep System pro E power cabinet arrangements. Its dedicated top/bottom application supports professional low-voltage distribution installations where enclosure compatibility, mechanical protection and coordinated assembly are important.

Reliable IP40 Enclosure Protection for Low-Voltage Switchboards

ABB System pro E power is a modular low-voltage switchboard system developed for electrical distribution applications in industrial, commercial and infrastructure environments. Its coordinated range of cabinet structures, doors, panels and mounting accessories enables switchboard manufacturers to configure enclosures for different equipment layouts and installation requirements.

The ABB PTBB3050 IP40 blind top/bottom panel is specified for compatible 300 mm wide × 500 mm deep cabinet arrangements. By closing a designated upper or lower opening, the panel contributes to the physical enclosure boundary and supports a coordinated protective arrangement within the switchboard structure.

Under the ingress protection classification system defined by IEC 60529, IP40 identifies an enclosure protected against access and ingress by solid objects of 1 mm diameter and greater, with no specified protection against water ingress. The PTBB3050 is designated for IP40 arrangements, but the completed switchboard's protection rating depends on the entire enclosure construction and correct installation of all associated components.

The blind panel configuration is appropriate where a closed upper or lower cabinet surface is required rather than a dedicated cable-entry or ventilation opening. This can be useful in electrical distribution assemblies where the cabinet layout does not require cables or ventilation to pass through the selected enclosure position.

Where cable access or ventilation is necessary, an appropriate compatible ABB enclosure accessory should be selected. Unauthorised modifications to a blind panel can affect the intended protection and mechanical characteristics of the completed cabinet.

The specified 300 mm width and 500 mm depth identify the nominal cabinet configuration for which the PTBB3050 is intended. These values should not automatically be interpreted as the exact manufactured outside dimensions of the individual panel, which may differ according to the mounting and enclosure design.

Correct installation is essential for achieving the intended protective performance. The ABB PTBB3050 should be fitted using the mounting arrangements specified in the relevant System pro E power documentation. The panel does not independently establish the electrical ratings, environmental suitability or ingress protection classification of the finished switchboard.
