Hager ARM975U MCB with Arc Fault Detection – Advanced Safety for High-Demand Installations

The Hager ARM975U combines MCB overcurrent protection with integrated Arc Fault Detection Device (AFDD) technology to deliver advanced electrical safety.

  • Dual Protection: MCB overcurrent safety and AFDD arc fault prevention in one device.
  • C-Curve Tripping: Handles high start-up currents without nuisance tripping.
  • Space-Saving Design: Single-module size maximises consumer unit capacity.
  • Durable Construction: Built to perform reliably in demanding installation environments.
