This FRBdM in 1+N and 2-pole is a high-quality residual current circuit breaker and miniature circuit breaker combination with line voltage-dependent tripping and a wide variety of rated tripping currents. The built-in electronics precisely monitors where the currents flow. The difference between harmless and critical residual currents will be detected. Its integrated digital technology offers predictive diagnostics of the level of leakage current via LED indication.
The FRBdM-RCD/MCB is compatible with Busbars. A twin-purpose terminal (lift/open-mouthed) is available for easy and quick mounting at the top and bottom.
