1STQ002036B0000 ABB PTAB3090 System pro E Power Internal Arc-Resistant Blind Top Panel 300 x 900 mm

Why Choose the ABB PTAB3090 System pro E Power Internal Arc-Resistant Top Panel?

The ABB PTAB3090 is a robust internal arc-resistant blind top panel designed for use with ABB System pro E Power low-voltage main distribution switchboards. Manufactured for electrical distribution assemblies requiring enhanced operator protection, this specialised enclosure component measures 300 mm wide × 900 mm deep and incorporates an internal arc pressure-relief arrangement.

As part of the advanced ABB System pro E Power series, the PTAB3090 supports the construction of modular electrical switchboards with passive internal arc fault protection. Its integrated pressure-relief flaps are designed to open upwards during an internal arc event, allowing hot gases and pressure to escape away from personnel positioned in front of the switchboard.

The PTAB3090 is intended for use in appropriately configured internal arc-resistant switchboard assemblies up to 4000 A. Although designed for assemblies incorporating IP65 enclosure panels, the pressure-relief flap arrangement results in a completed switchboard protection rating of IP41 when installed according to the manufacturer's specified configuration.

Key Advantages

• Purpose-designed internal arc-resistant top panel for ABB System pro E Power switchboards.
• 300 mm width × 900 mm depth for compatible modular enclosure structures.
• Integrated upward-opening pressure-relief flaps help direct internal arc gases away from operators.
• Supports correctly configured switchboard assemblies up to 4000 A.
• Designed for use with IP65 enclosure components in internal arc-resistant assemblies.
• Supports passive arc fault protection without requiring an electrically operated release mechanism.
• Compatible with the modular construction principles of the ABB System pro E Power range.

Key Features

• ABB System pro E Power modular switchboard accessory.
• PTAB3090 internal arc-resistant blind top panel.
• 300 mm nominal width.
• 900 mm nominal depth.
• Two integrated pressure-relief flaps for upward venting during an internal arc fault.
• Designed for assemblies using IP65 external enclosure panels.
• IP41 completed assembly protection rating when configured with the specified arc-relief arrangement.
• Supports internal arc-resistant switchboard configurations with a maximum specified short-time withstand current of 65 kA.
• Suitable for compatible switchboard assemblies incorporating Form 3b or Form 4b segregation.
• Designed for integration into low-voltage power distribution and industrial switchgear installations.

Reliable Internal Arc Protection for Electrical Distribution Systems

Internal arc faults can generate extremely high temperatures, rapidly expanding gases and substantial pressure inside electrical switchboards. Properly designed internal arc-resistant enclosures incorporate pressure-relief features that help manage these effects and reduce the risk to personnel working near electrical distribution equipment.

The ABB PTAB3090 incorporates two pressure-relief flaps that open upwards during an internal arc event, helping direct gases away from the front operating area. This passive protection arrangement forms part of ABB's System pro E Power internal arc-resistant switchboard solution.

For the specified arc-resistant configuration, the switchboard must incorporate suitable IP65 enclosure panels, the dedicated top arrangement, correctly selected busbars and appropriate internal segregation. The PTAB3090 must be installed as part of a complete assembly engineered to meet ABB's applicable design requirements; the panel alone does not establish an internal arc protection rating for the finished switchboard.
