1STQ007639A0000 ABB PPRA1820 IP30 Aerated External Right Rear Panel 1800 x 625 mm System pro E Power

Why Choose the ABB PPRA1820 IP30 Aerated External Right Rear Panel 1800 × 625 mm?

The ABB PPRA1820 (1STQ007639A0000) is an IP30 aerated external right-hand rear panel designed for the ABB System pro E Power modular switchboard range. With nominal panel dimensions of 1800 mm high × 625 mm wide, this specialist enclosure accessory is intended for the right-hand rear section of compatible 1250 mm wide low-voltage distribution switchboards.

Unlike a solid blind rear panel, the PPRA1820 features an aerated construction with ventilation openings to support airflow through the electrical enclosure. This makes it suitable for switchboard designs where internal equipment generates heat and a planned ventilation arrangement is required. The panel provides a coordinated external covering while contributing to the thermal management strategy of the completed assembly.

Manufactured from pickled sheet steel, the PPRA1820 combines durable enclosure construction with a system-specific mounting arrangement. It is designed to work alongside the corresponding ABB PPLA1820 left-hand aerated rear panel (1STQ007640A0000) in compatible two-part rear panel configurations. As a genuine ABB System pro E Power component, it supports professional switchboard manufacturing, installation and maintenance.

Reliable Ventilation and IP30 Protection for Wide Electrical Switchboards

Ventilation is an important consideration in electrical switchboard design because circuit breakers, busbars and other power distribution components generate heat during normal operation. The ABB PPRA1820 provides an aerated right-hand rear enclosure covering that helps facilitate airflow through compatible System pro E Power switchboards. Its ventilation openings form part of the overall thermal management arrangement rather than providing a guaranteed cooling capacity independently.

The IP30 protection classification provides protection against access with a tool and the ingress of solid objects measuring at least 2.5 mm. The second digit of zero means that IP30 does not specify water ingress protection. Where an IP31 enclosure is required, appropriate ABB top sealing accessories must be incorporated to provide protection against vertically falling water drops. The final protection rating depends on the complete switchboard, including its doors, panels, ventilation openings and other enclosure components.

The PPRA1820 is designed for the right-hand rear position of a compatible 1800 mm high, 1250 mm wide switchboard structure. The corresponding ABB PPLA1820 provides the left-hand section where a complete two-part aerated rear covering is required. Electrical panel builders should verify the mounting arrangement, airflow requirements, internal clearances and enclosure protection classification against the applicable ABB System pro E Power assembly documentation.
