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.
