Protector Relays

Protector Relays: An extensive range of electronic control products providing continuous monitoring and protection of any electrical parameter. When the monitored parameter deviates from the desired set point limit, the relay will operate to prevent damage to the power asset. Designed to suit a wide variety of applications the range offers both traditional and technologically advanced products, from single parameter units through to multifunctional microprocessor based protection relays.

This versatile range features a host of DIN-rail or wall mounted protectors offering numerous trip functions for single and three-phase power systems, including over and under-voltage, current, frequency, three-phase sequence, phase failure and phase balance. For the specific protection of generator sets, the range offers unbalanced current, reverse power flow, reverse VAr, syncro-check and under/over-speed trip relay functions. Various dc models provide protection of battery and UPS systems and a range of temperature protection products is ideal to prevent the damaging effects of overheating.
