Why Choose the ABB CA45RZ1 ComfortLine Compact Distribution Board?
The ABB CA45RZ1 is a ComfortLine Compact low-voltage distribution board designed for wall-mounted electrical distribution installations. Supplied under ABB order code 2CPX052289R9999, the CA45RZ1 forms part of ABB's DESUJ Sub Distribution product group and provides a robust enclosure for professional modular distribution equipment.
The CA45RZ1 provides 192 space units across 4 rows in a 4-panel-width (4PW) arrangement. It is specifically configured for DIN rail-mounted devices with N/PE screw terminals, a DIN rail spacing of 150 mm and a closing flange, providing an organised platform for professional low-voltage distribution assemblies.
With external dimensions of 1050 mm wide × 800 mm high × 160 mm deep, the CA45RZ1 combines extensive modular capacity with a relatively shallow enclosure. Its IP44 protection and sheet-steel door construction make it a practical choice for compatible indoor commercial, residential and industrial distribution installations.

High-Capacity Modular Distribution in a Wide Enclosure
Modular distribution boards provide structured housing for circuit protection, switching equipment, terminals and associated low-voltage wiring. Wide multi-panel enclosures allow large numbers of DIN rail devices to be arranged into clearly defined sections while maintaining convenient access for installation, inspection and future maintenance.
The ABB CA45RZ1 provides 192 space units across 4 rows within a 1050 × 800 × 160 mm enclosure. Its 4PW arrangement, 150 mm DIN rail spacing, N/PE screw terminals and closing flange make it particularly suitable for professional distribution assemblies requiring substantial modular capacity and conventional screw-terminal connections.
Typical Applications
- Commercial building electrical distribution.
- Industrial low-voltage sub-distribution systems.
- Residential and multi-occupancy building installations.
- Building-services electrical distribution.
- High-capacity DIN rail distribution assemblies.
- ABB ComfortLine Compact modular distribution systems.
