Selection
Selection / Use Cases
Use this MCCB when:
Leakage Monitoring
Suitable for systems requiring residual current protection and status visibility.
Remote Communication
Supports RS485-based integration for panel and facility monitoring.
Adjustable Protection
Built for load coordination environments that need configurable trip settings.
- Determine the required frame current and rated current based on the circuit's load and protection needs (63A to 800A).
- Verify the ultimate and operating short-circuit breaking capacities (Icu, Ics) match the potential fault levels of the installation.
- Confirm compatibility with the system's rated operating voltage, choosing between AC400V or AC690V variants where applicable.
