About Heavy Duty DSL Busbar System
Standard Features
Overview: The Heavy Duty DSL Busbar System is engineered for demanding crane and industrial power distribution applications. With a multi-conductor design, working voltage up to 600V, and an operating temperature range of -30°C to 55°C, it handles the toughest industrial environments reliably and safely.
Multi-Conductor Design: Multiple conductors in a single housing simplify installation and reduce the number of separate conductor rails required, making the system more compact and easier to manage on long crane runways.
Flexible Protection Rating: Available with IP20 protection as standard, or upgraded to IP23 with rubber sealing for installations exposed to water spray or higher levels of environmental contamination.
