1STQ007138A0000 ABB PTBO3070 IP65 Open Top/Bottom Panel 300 x 700 mm

Why Choose the ABB PTBO3070 IP65 Open Top/Bottom Panel?

The ABB PTBO3070 (1STQ007138A0000) is a dedicated IP65 open top/bottom enclosure accessory designed for compatible ABB System Pro E Power low-voltage electrical switchboards and distribution cabinets. This original ABB component provides an open top or bottom enclosure configuration for switchboard installations where cable routing, equipment connections or other appropriately protected openings need to be accommodated.

Identified by ABB as PTBO3070 — IP65 OPEN TOP/BOTTOM W=300MM D=700MM, the product is specified for a 300 mm nominal enclosure width and 700 mm nominal enclosure depth. Its open configuration distinguishes it from blind top/bottom panels and makes it suitable for compatible electrical enclosure arrangements requiring a designated opening rather than a completely closed panel.

As part of the ABB System Pro E Power series, the PTBO3070 supports professional modular switchboard construction. Its IP65 configuration designation makes it relevant to electrical distribution assemblies designed for enhanced dust and water ingress protection, provided that the complete enclosure, opening treatments, seals and installed accessories are correctly selected and assembled to achieve the required protection rating.

IP65 Enclosure Integration and Open Top/Bottom Installation

The ABB PTBO3070 is intended for compatible System Pro E Power switchboard structures requiring an open top or bottom enclosure arrangement. Unlike a blind panel, which provides a solid closure, an open top/bottom component accommodates a designated opening within the enclosure configuration.

Such arrangements can be relevant where cables, electrical connections or other equipment interfaces need to pass through or be incorporated into a switchboard structure. The actual opening dimensions, permitted cable-entry arrangements and compatible supplementary accessories must be established from the relevant ABB technical documentation.

The IP65 classification, defined by IEC 60529, combines two protection characteristics. The first digit, 6, indicates a dust-tight enclosure classification and protection against access to hazardous parts with a wire. The second digit, 5, indicates protection against water jets from any direction under the specified test conditions.

Importantly, an open top/bottom panel does not independently make an exposed opening dust-tight or water-jet resistant. The IP65 designation identifies the intended enclosure configuration, while the achieved protection rating depends on the completed assembly. Suitable sealing systems, covers, cable-entry components or other manufacturer-approved accessories may be necessary to maintain the specified protection level.

The product's 300 mm nominal width and 700 mm nominal depth are selection dimensions for the compatible System Pro E Power cabinet configuration. They should not be interpreted as independently verified overall manufactured dimensions or as the dimensions of the open aperture.

For switchboard builders, selecting the correct open top/bottom component is an important part of enclosure planning. The PTBO3070 allows the specified cabinet configuration to be incorporated into an ABB modular assembly while leaving the treatment of the opening to the approved installation design.

Before installation, engineers should verify the intended mounting position, the compatible enclosure structure, any required sealing or cable-entry accessories and the protection rating of the complete assembly. Additional openings, modifications or incorrectly fitted components can affect the enclosure's ingress protection performance.
