- High Durability and Reliability
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 required rated current (In) and ultimate short-circuit breaking capacity (Icu) based on system load and fault levels.
- Select appropriate operating voltage (AC400V or AC690V) and number of poles (3 or 4) to match the electrical system specifications.
- Consider the installation environment and wiring mode requirements (horizontal or vertical wiring options available for certain variants).
