Electronical relay protection devices controlled by microprocessor

Protection against thermal overload, earth-fault, overcurrent, overvoltage and phase unbalance are some important features that are provided in modern multifunctional protective relays. The relay can be used for protection of motors, transformers and feeders, requiring a single-, two- or three-phase over-current and/or overload protection and non-directional earth-fault protection.

We offer ABB and Thytronic protection relays.
