Product Overview
BHP low-voltage switchboards receive power from a utility supply or transformer and distribute it to downstream feeders and distribution equipment.
Designed for main service and power distribution applications, the low-voltage switchboard series is currently undergoing evaluation for UL certification to UL 891.
It offers main bus ratings up to 4,000 A and short-circuit current ratings (SCCR) up to 100 kA.
Applications
- Industrial complexes & plants
- Commercial & institutional buildings
- Data centers & critical facilities
- Utility service entrance
High Reliability & Safety
- UL 891 tested and approved
- Dead-front, isolated bus design
- Safe arc-blow pressure relief channel
- User safety considerations
Modularity & Scalability
- Modular sections L/S/I/G
- Easy to add feeder sections
- Flexible incoming / outgoing layout
