ABB 2CPX042253R9999 Busbar NH-Disconnector - DIN EN 61439-3

Feature: Accommodates four NH1 fuse switch disconnectors within a 185 mm busbar system for a compact, high-density protection module. Benefit: Increases protection capacity without expanding panel footprint, enabling slim, efficient switchgear layouts for 850 A continuous operation. Application: Ideal for machine builders and panel shops upgrading to higher protective density while maintaining service access. Feature: DIN EN 61439-3 and DIN EN 61439-2 compliance with CE marking and RoHS/REACH declarations. Benefit: Reduces regulatory risk, accelerates time-to-commission, and simplifies supplier declarations for auditors. Application: Suitable for panels requiring formal certification streams in automatic control and safety-critical installations. Feature: 500 mm width, 900 mm height, 159.5 mm depth enclosure with WR rail mounting and 120 DIN place units. Benefit: Provides predictable mounting geometry and extensive modularity, enabling rapid wiring and organized labeling. Application: Fits standard cabinet footprints in industrial control rooms and process automation panels. Feature: Includes busbar holders ZX522 and 90-degree closure for easy alignment and secure enclosure sealing. Benefit: Improves mechanical alignment during assembly, reduces commissioning time, and enhances enclosure integrity against dust ingress. Application: Preferred when horizontal busbar alignment and robust enclosure sealing are required in harsh environments. Feature: 3P configuration with 4 fuse switch disconnectors and 4 mountable devices. Benefit: Streamlines device loading, simplifies maintenance scheduling, and supports scalable protection schemes. Application: Works well in grid units up to 900 mm wide with 120 DIN place units for future expansion.
