Why Choose the ABB PTBB2550 System pro E Power IP40 Blind Top/Bottom Panel?
The ABB PTBB2550 is a dedicated IP40 blind top/bottom enclosure component designed for compatible ABB System pro E power low-voltage switchboards. Specified for a nominal 250 mm width and 500 mm depth, this accessory supports the construction of enclosed top or bottom sections within modular main distribution switchboards.
Identified by the manufacturer designation IP40 BLIND TOP/BOTTOM W=250MM D=500MM, the PTBB2550 provides a purpose-designed blanking solution for designated enclosure positions. Its blind configuration is intended for applications where a compatible top or bottom enclosure area requires a closed panel rather than an opening for cables or ventilation equipment.
With ABB order code 1STQ009370A0000, the PTBB2550 belongs to the System pro E power enclosure accessory range. It supports professional panel builders and switchboard manufacturers in selecting the appropriate components for compatible IP40 enclosure arrangements.

Blind Top and Bottom Enclosure Integration for IP40 Switchboards
Top and bottom enclosure components form part of the external structure of modular low-voltage switchboards. Appropriate blanking panels help close designated enclosure areas and support the intended mechanical arrangement. Where an installation does not require a particular cable entry or ventilation opening, a blind component provides a suitable configuration for that enclosure position.
The ABB PTBB2550 is specified for 250 mm wide and 500 mm deep System pro E power arrangements requiring a blind top or bottom enclosure component. Its IP40 designation identifies the intended protection configuration, but the component does not independently establish the ingress protection rating of an incomplete enclosure.
Under IEC 60529, IP40 describes protection against solid foreign objects of 1 mm diameter or greater and against access to hazardous parts with a wire, without a specified water-ingress protection level. The completed switchboard's IP rating depends on the installation of all compatible panels, doors, joints, cable entries and associated enclosure components. Compliance with applicable IEC 61439 requirements must be assessed for the complete assembly.
Typical Applications
- ABB System pro E power main distribution switchboards.
- Blind top enclosure arrangements in modular electrical cabinets.
- Blind bottom enclosure arrangements in compatible distribution boards.
- IP40 low-voltage switchboard enclosure configurations.
- 250 mm wide and 500 mm deep designated enclosure positions.
- Industrial electrical distribution panels.
- Commercial building main distribution boards.
- Manufacturing facility electrical switchboards.
- Electrical plant room distribution assemblies.
- Professional electrical panel building and switchboard manufacturing.

Frequently Asked Questions
What is the ABB PTBB2550 used for?
The ABB PTBB2550 is a blind top/bottom enclosure component designed for compatible ABB System pro E power switchboards requiring the specified IP40 enclosure arrangement.
What dimensions are specified for the ABB PTBB2550?
The PTBB2550 is specified for a nominal 250 mm width and 500 mm depth.
What does blind top/bottom mean?
The term blind top/bottom identifies a blank enclosure component intended for a compatible top or bottom installation position, rather than a component with a designated opening for cable entry or ventilation.
What IP rating is associated with the ABB PTBB2550?
The manufacturer specifies the PTBB2550 for an IP40 enclosure configuration. The actual protection rating depends on the complete assembled switchboard and the correct installation of all enclosure components.
What does IP40 mean?
IP40 indicates protection against access to hazardous parts with a wire and against solid foreign objects of 1 mm diameter or greater. It does not specify protection against water ingress.
Which ABB switchboard system is compatible with the PTBB2550?
The PTBB2550 belongs to the ABB System pro E power range and is intended for compatible modular low-voltage main distribution switchboards.
What is the ABB order code for the PTBB2550?
The manufacturer order code for the ABB PTBB2550 is 1STQ009370A0000.
Does the ABB PTBB2550 include a complete switchboard enclosure?
No. The PTBB2550 is an enclosure accessory, not a complete switchboard. Supporting framework components, doors and other panels must be selected according to the intended assembly configuration.
Can the ABB PTBB2550 be incorporated into an IEC 61439 switchboard assembly?
The PTBB2550 can be incorporated into compatible ABB System pro E power assemblies designed to meet applicable IEC 61439 requirements. Final compliance, including the achieved enclosure IP rating, depends on the completed assembly design, installation and verification.
