1STQ002026B0000 ABB PTAB8096 IP65 Blind Internal Arc Top Panel 800 x 900 mm

Why Choose the ABB PTAB8096 IP65 Blind Internal Arc Top Panel?

The ABB PTAB8096 (1STQ002026B0000) is a specialised internal arc fault-resistant blind top panel designed for ABB System pro E Power low-voltage distribution switchboards. Manufactured for industrial electrical distribution applications, this protective enclosure component incorporates a dedicated pressure-relief arrangement that helps manage the effects of an internal electrical arc fault.

As part of the ABB System pro E Power modular switchboard system, the PTAB8096 provides an engineered solution for installations requiring enhanced operator protection and controlled arc-fault pressure relief. Its construction features two integrated relief flaps that open upwards during an internal arc event, helping release hot gases and pressure away from personnel positioned in front of the switchboard.

Designed for switchboard structures measuring 800 mm wide and 900 mm deep, the PTAB8096 is intended for internal arc fault-resistant assemblies rated up to 4000 A, subject to the specified ABB configuration requirements. Although the associated enclosure construction uses IP65 external panels, the pressure-relief flaps result in a final assembled protection rating of IP41 for the specified arc-resistant configuration.

Key Advantages

• Purpose-designed internal arc fault-resistant top panel for ABB System pro E Power switchboards.
• 800 mm width and 900 mm depth for compatibility with corresponding ABB enclosure structures.

Reliable Internal Arc Fault Protection for Electrical Switchboards

Internal arc faults can generate substantial heat, pressure and ionised gases inside electrical distribution equipment. The ABB PTAB8096 arc-resistant top panel is engineered to support controlled upward pressure relief through its two integrated flaps. During an internal arc event, the flaps are designed to open and release the resulting gases through the top of the switchboard, helping reduce pressure accumulation within the enclosure and limiting exposure at the front operating area.

The PTAB8096 forms part of ABB's wider System pro E Power internal arc protection solution. Correct performance depends on the complete switchboard configuration, including the specified enclosure panels, segregation arrangements, busbars and dedicated top components. For the applicable arc-resistant design, ABB specifies IP65 external panels, Form 3b or Form 4b segregation, a maximum short-time withstand current of 65 kA and a maximum operating voltage of 480 V AC. Because the pressure-relief flaps create openings during operation, the final protection rating of this configured assembly is IP41 rather than IP65.

The System pro E Power platform supports modular electrical distribution board construction in accordance with IEC 61439-2, while ABB's arc protection solutions are developed around the internal arc testing principles of IEC TR 61641. The PTAB8096 must be installed as part of an appropriately designed and verified assembly rather than treated as a standalone arc protection device. ABB also recommends maintaining at least 600 mm clearance between the enclosure top and ceiling to support thermal performance and maintenance access.
