Why Choose the ABB CA28R ComfortLine Compact Distribution Board?
The ABB CA28R is a robust ComfortLine Compact surface-mounted distribution board designed for professional indoor electrical sub-distribution installations. It combines a durable enclosure with a steel door and DIN-rail equipment mounting, providing an organised platform for protective, switching and modular electrical devices.
Designed with 2 columns, 7 rows and 168 modular space units, the CA28R provides substantial installation capacity while maintaining a relatively shallow enclosure depth. The DIN rails have a 150 mm row spacing, and the distribution board incorporates N/PE terminal arrangements to support efficient wiring and structured panel assembly.
With external dimensions of 550 mm wide × 1250 mm high × 160 mm deep, the CA28R is rated for 400 V AC at 50/60 Hz and currents up to 125 A. Its IP44 ingress protection, IK07 mechanical impact resistance and RAL 9016 finish make it well suited to commercial, industrial and building-services distribution applications.
