ABB PTAB4070 System pro E Power internal arc-resistant blind top panel measuring 400 x 700 mm, featuring upward-opening pressure-relief flaps for compatible low-voltage distribution switchboards.
£154.15
The ABB PTAB4070 is a durable and purpose-designed internal arc-resistant blind top panel for ABB System pro E Power low-voltage distribution switchboards. Designed for compatible electrical enclosure structures measuring 400 mm wide × 700 mm deep, this specialised top cover incorporates pressure-relief flaps that help manage the effects of internal electrical arc faults.
As part of the ABB System pro E Power modular switchboard series, the PTAB4070 supports the construction of internal arc-resistant electrical distribution assemblies. Its two upward-opening pressure-relief flaps allow hot gases and pressure generated during an internal arc fault to escape through the top of the switchboard, helping protect personnel positioned in front of the equipment.
The PTAB4070 is designed for use in specified internal arc-resistant switchboard configurations rated up to 4000 A. Although the system requires IP65 external enclosure panels, the completed arc-resistant assembly achieves an IP41 protection rating because of the pressure-relief flap arrangement. Its modular design makes it suitable for industrial power distribution installations requiring dependable enclosure construction and enhanced operator protection.
Internal electrical arc faults can generate intense heat, rapidly expanding gases and significant pressure within low-voltage distribution switchboards. Properly engineered internal arc-resistant enclosures incorporate pressure-relief systems that help manage these effects and reduce the risk of injury to personnel working near electrical equipment.
The ABB PTAB4070 features two pressure-relief flaps designed to open upwards during an internal arc event. This passive pressure-release arrangement helps direct hot gases away from the front operating area of the switchboard, supporting ABB System pro E Power internal arc protection solutions.
To achieve the specified internal arc-resistant configuration, the complete switchboard must incorporate the appropriate IP65 external panels, dedicated top arrangement, compatible busbar system and specified internal segregation. The PTAB4070 is one component of this engineered protection system, and the completed assembly must comply with ABB's applicable design and installation requirements.

The ABB PTAB4070 is an internal arc-resistant blind top panel designed for ABB System pro E Power switchboards. It incorporates pressure-relief flaps that help direct hot gases upwards during an internal electrical arc fault, supporting enhanced operator protection in correctly configured low-voltage distribution assemblies.
The PTAB4070 is designed for compatible switchboard enclosure structures measuring 400 mm wide × 700 mm deep.
The PTAB4070 is intended for internal arc-resistant switchboard configurations incorporating IP65 external enclosure panels. However, because the top panel includes pressure-relief flaps, the completed specified assembly achieves an IP41 protection rating rather than IP65.
The panel features two upward-opening pressure-relief flaps that allow expanding gases and pressure to escape through the top of the switchboard during an internal arc event. This helps direct the effects of the fault away from personnel positioned in front of the equipment.
The PTAB4070 is designed for compatible ABB System pro E Power switchboard structures measuring 400 mm wide × 700 mm deep. It supports specified internal arc-resistant configurations up to 4000 A, subject to the complete assembly meeting ABB's applicable requirements for enclosure panels, busbars, segregation and electrical ratings.
ABB System pro E Power switchboard components are designed to deliver reliable, modular and safety-focused electrical distribution solutions. The PTAB4070 internal arc-resistant blind top panel supports passive arc fault protection in compatible assemblies, helping electrical engineers, industrial contractors and switchboard manufacturers construct robust low-voltage distribution systems with enhanced operator protection.
