Single-phase voltage and current protection relay 1–63 A for DIN rail, GKE-63E

Single-phase voltage and current protection relay for DIN rail, Tense

The advanced Tense GKE-63E protection relay with integrated microprocessor and True RMS function is designed for comprehensive protection of electrical equipment in single-phase networks. The device continuously measures with high accuracy and displays voltage and current instantaneous values on a dual display. It provides reliable protection against overvoltage, undervoltage, current overload (thermal protection), and internal device overheating. The relay is equipped with memory to record the last fault type and an automatic recovery function with adjustable time delay. Thanks to its compact modular design, it takes up minimal space in the distribution board and mounts on a standard 35 mm DIN mounting profile.
