What it is

The Hager ADA140U is a single pole RCBO that combines a 40A B curve miniature circuit breaker with 30mA Type A residual current protection in a one module width. It carries a 10kA breaking capacity and protects a single final circuit against overcurrent and earth leakage faults at the point of use.

Before you order

  • Confirm the consumer unit or enclosure accepts a single pole, one module RCBO and that the busbar and terminal layout suit the device.
  • Check the circuit design calls for a 40A B curve device; other ratings and curves in the same range suit different circuits.
  • Confirm 30mA Type A residual current protection is the required sensitivity and type for the installation.
  • Check the required breaking capacity against the prospective fault current at the point of installation.
