FeaturesThe User ManualGKE-63T is an advanced three-phase voltage and current protection relay designed to protect your electrical appliances against the harshest grid conditions.

Thanks to its microcontroller-based structure, it operates with high precision and provides reliable protection.

Device

offers effective protection against many failures such as over/under voltage, over current, voltage asymmetry, phase sequence failure and overheating.

It provides security separately for both single circuit and each phase with synchronous and asynchronous mode options.

Easily adapts to different applications with adjustable current value in the range of 1-63A, wide voltage range, automatic reset and delay settings.

Provides clear information to the user thanks to the last fault record and internal temperature indicator.

With its DIN rail-mounted compact structure, easy installation and long-lasting design, theGKE-63T is an ideal solution for safely protecting your engines and devices.

Highlights Microcontroller based: Provides high sensitivity and reliability.

Comprehensive protection functions: Over/under voltage protection Over current (thermal) protection Voltage asymmetry protection Phase sequence protection Over heat protection Fast trip against short circuit (0.04 s) Interrupts the circuit at neutral break, performs Voltage Protection and Current Protection operations separately.

There is no leakage current protection feature.

Working modes Synchronous mode: 3-phase single circuit protection Asynchronous mode: Each phase independent protection Wide setting ranges Current: 1-63A Undervoltage: 80-210V Overvoltage: 220-300V Voltage asymmetry: 20-99V Opening delay: 1-300s Reset delay: 1-600s
