Article Overview
ABB REX640 protection relays are available in two case widths: narrow (5 module slots) and standard (7 module slots), with detailed installation dimensions provided for wall and roof mounting.
Case Sizes and Module Slots
The ABB Relion REX640 relay comes in two physical case widths:
- Narrow case: accommodates 5 module slots
- Standard case: accommodates 7 module slots Both case sizes support identical software options and functionality, allowing flexibility in panel design and relay configuration .
Installation Dimensions
For proper installation, ABB provides wall and roof mounting guidelines:
- Mounting spacing: Ensure adequate clearance around the relay for ventilation, wiring, and maintenance access.
- Panel cutout: The relay front panel is designed to fit standard cutouts for easy integration into switchgear or control panels.
- Mounting hardware: Use the recommended screws and brackets specified in ABB installation manuals to secure the relay safely .
Additional Considerations
- Modular design: The REX640's modular hardware allows for high customization, enabling adaptation to changing protection requirements over the relay's lifecycle .
- Connectivity: Relays can be connected to local or remote HMIs (LHMI/SHMI) for monitoring and control, which may influence panel layout and spacing .
- Compliance: The relay is fully compliant with IEC, ANSI, and CN standards, ensuring compatibility with standard switchgear dimensions and mounting practices . For precise height, width, and depth measurements, ABB's official installation manuals or product datasheets should be consulted, as they provide exact millimeter specifications for both narrow and standard cases, including cutout dimensions and recommended clearances. This ensures proper fit and safe operation within electrical panels.
