Supplemental Motor Protection

This family of dedicated function electronic motor protection relays offers state-of-the-art supplementary protective functions that are easily added and applied to motor control circuits. A full range of products exists to allow selective addition of motor-protective enhancing functions to meet specific application requirements.

Low-level (arcing) ground faults are below the fuse or circuit breaker rating and therefore go undetected until a much larger problem develops. The Allen-Bradley Arcing Ground Fault Detection System is designed to sense these low-level faults.

The Allen-Bradley Motor Winding Heater is intended for use with 3-phase AC motors to guard against damage caused by condensation build-up on motor windings, which can occur in high-humidity environments during motor off times.
