3 Phase under / over voltage monitoring relay with phase control, voltage supply 220V-240V AC, DIN Rail Mount, NO+NC, TENSE (Made in Turkey)

The GKT-03F by Tense Electronics is an analogue adjustable voltage control relay designed to protect three-phase systems without a neutral connection from voltage fluctuations and phase sequence errors. 

Key Functions

• Over-Voltage Protection: Monitors and trips if voltage exceeds the set limit (adjustable between 230V - 300V AC).
• Under-Voltage Protection: Monitors and trips if voltage drops below the set limit (adjustable between 140V - 210V AC).
• Phase Sequence Control (GKM-03F): Ensures the correct order of phases; the relay will not activate if the sequence is reversed .
• Phase Failure Protection: Detects the absence of a phase and deactivates the relay to prevent equipment damage.
• Time delays adjustable for Fault detection and Fault reset
