## Summary description

ABB UK624E3 is a combiner/junction box designed for photovoltaic installations. It provides a protected point for connecting multiple PV strings and routing DC outputs to inverters. Key parameters include model UK624E3; suitable for solar panel accessory applications where reliable string connection, cable routing and overcurrent protection integration are required.

## Long description

ABB UK624E3 is a consumer unit / combiner (junction) box intended for indoor installation in photovoltaic systems. It provides a protected enclosure for combining multiple PV strings and routing DC outputs to inverters. The enclosure is made of thermoplastic with a powder-coated metal door in RAL 9016, has IP30 protection, class II double insulation and a 120° opening door with TIP-in closure. The unit accepts top, bottom, side and rear cable entry via pre-punched slide parts and rear knockouts, and includes an assembled device carrier with removable device support and integrated cable fastening rail.
Advantages
The ABB UK624E3 combines a compact 24-space thermoplastic enclosure with a metal trim frame and powder-coated steel door for improved durability. It meets relevant standards (EN 60670-24), offers IK07 impact resistance and glow-wire resistance up to 850 °C. The unit includes N/PE screw terminals, a 90° press-and-turn closure for covers, and is delivered assembled with device carrier and removable support for easier installation and maintenance.
Suitable for
Indoor photovoltaic combiner/junction box installations
Combining multiple PV strings and routing DC outputs to inverters
Small to medium rooftop or commercial solar projects requiring a compact consumer unit
Installations requiring pre-punched cable entry points for top, bottom, side and rear wiring
When it may not be suitable
This unit has an IP30 rating and is designed for internal use only, so it is not suitable for outdoor installations or environments with high humidity, dust or water exposure. It also lacks integrated AC distribution and is intended for DC combiner functions; projects needing full AC distribution boards or higher ingress protection should choose a different enclosure.
