Reliable Protection for Industrial Power Distribution

Moulded case circuit breakers such as the ABB Tmax T5H are essential for protecting low-voltage electrical systems from overloads, short circuits and earth fault conditions. By disconnecting the circuit during abnormal events, the breaker helps protect equipment, cabling and downstream electrical components from damage.

The PR222DS/P-LSIG release provides adjustable electronic protection functions, including ground fault protection, allowing engineers to coordinate protection settings across complex electrical installations. This supports improved selectivity, reduced downtime and safer operation in industrial and commercial power networks.

Typical Applications

  • Industrial switchboards and distribution panels.
  • Main incoming and feeder protection.
  • Commercial building power distribution.
  • Manufacturing and process plant installations.
  • OEM machinery and electrical control panels.
  • Low-voltage power distribution networks requiring ground fault protection.
