Why Choose the ABB PTBB2536 IP65 Blind Top/Bottom Panel 250 × 300 mm?
The ABB PTBB2536, manufacturer order code 1STQ007071A0000, is an IP65 blind top/bottom enclosure accessory for compatible low-voltage electrical distribution switchboards within the ABB System pro E Power range. Identified by the authoritative manufacturer designation IP65 BLIND TOP/BOTTOM W=250MM D=300MM, this component is specified for an enclosure configuration with a nominal width of 250 mm and depth of 300 mm.
Designed for professional electrical panel building, the ABB PTBB2536 provides a blind, or unperforated, top/bottom closure solution for designated System pro E Power enclosure arrangements. Blind enclosure components are used where an enclosed surface is required without the intentional openings associated with ventilated, cable-entry or pre-punched alternatives.
The manufacturer's IP65 designation identifies the intended ingress protection application. Under IEC 60529, IP65 denotes a dust-tight enclosure and protection against water jets when the complete assembly is correctly designed, installed and assessed to that classification. The IP65 marking on this accessory does not independently establish the ingress protection rating of an entire switchboard.
With its 250 mm width and 300 mm depth references, the ABB PTBB2536 is intended for compatible enclosure configurations requiring this specific top or bottom arrangement. Its dedicated model number and ABB order code enable accurate product selection for new installations, enclosure modifications and maintenance projects.

IP65 Blind Top and Bottom Protection for ABB Switchboards
The ABB PTBB2536 is intended for compatible enclosure arrangements within the System pro E Power switchboard platform. Electrical distribution assemblies use enclosure panels, covers, structural members, doors and sealing components to establish the physical boundary around installed electrical equipment.
A blind top/bottom component provides a closure arrangement without intentional openings for ventilation or cable entry. This is particularly relevant where the switchboard design calls for an enclosed top or bottom surface rather than a perforated or open configuration. Any required cable-entry provisions must be planned separately using components appropriate to the intended enclosure protection level.
The manufacturer's IP65 reference is significant for applications where protection against dust and water jets is required. The first numeral, 6, indicates dust-tight protection, while the second numeral, 5, indicates protection against water jets in accordance with the applicable IEC 60529 test conditions.
However, an IP65-designated accessory does not automatically make a complete switchboard IP65. The achieved enclosure rating depends on the compatibility and correct installation of every relevant component, including doors, joints, seals, cable entries and other openings. The completed assembly must be assessed against the manufacturer's approved configuration and applicable standards.
The designation W=250MM D=300MM identifies a nominal enclosure width of 250 mm and depth of 300 mm. These values should be treated as configuration references rather than verified external measurements of the individual component. Exact panel dimensions, material, thickness, fixing positions and sealing details should be confirmed from ABB technical drawings.
Selecting the Correct 250 mm × 300 mm Blind Top/Bottom Component
When specifying the ABB PTBB2536, panel builders should confirm that the intended System pro E Power enclosure requires the manufacturer's 250 mm width and 300 mm depth configuration. Both dimensions are important because an enclosure accessory selected for an incorrect nominal size may not align with the required structural or sealing arrangement.
The product designation identifies a blind top/bottom component, but it does not independently confirm whether the supplied package contains one panel, multiple panels, fixing screws, gaskets or other sealing accessories. The exact delivery contents should be checked against the manufacturer's bill of materials before ordering.
For IP65 applications, the intended installation should be checked for the correct sealing system, fixing arrangement and enclosure compatibility. Unapproved drilling, cutting or modification may affect the finished enclosure's ability to meet its specified ingress protection requirements.
The model PTBB2536 and ABB order code 1STQ007071A0000 should be matched against the relevant System pro E Power assembly documentation. A nominal size match alone does not establish universal compatibility with every ABB enclosure or switchboard configuration.

Frequently Asked Questions
What is the ABB PTBB2536 1STQ007071A0000 used for?
The ABB PTBB2536, order code 1STQ007071A0000, is an IP65-designated blind top/bottom enclosure accessory for compatible ABB System pro E Power switchboards. It is intended to provide a blind closure arrangement for a designated enclosure surface.
What enclosure dimensions does the ABB PTBB2536 support?
The manufacturer designation specifies a nominal enclosure width of 250 mm and depth of 300 mm. These are configuration references and should not automatically be treated as the exact physical dimensions of the individual component. Detailed measurements should be confirmed from ABB technical drawings.
What does IP65 mean for the ABB PTBB2536?
IP65 indicates dust-tight protection and protection against water jets under the applicable IEC 60529 conditions. The ABB PTBB2536 is designated for an IP65 application, but the completed switchboard achieves that protection level only when all relevant enclosure components are correctly selected, installed and assessed.
Does the ABB PTBB2536 include both a top panel and a bottom panel?
The manufacturer designation identifies the product as BLIND TOP/BOTTOM, indicating its top/bottom enclosure application. It does not establish whether the supplied package contains one component or a pair of panels. The exact quantity and any included fixing or sealing accessories should be verified before ordering.
Is the ABB PTBB2536 compatible with every System pro E Power enclosure?
No universal compatibility should be assumed. The ABB PTBB2536 belongs to the System pro E Power product group and is specified for a W=250MM D=300MM blind top/bottom configuration. The enclosure structure, mounting arrangement and sealing requirements must be checked against ABB's applicable assembly documentation.
