Three-phase voltage and current protection relay, 1-63 A, for DIN rail, GKE-63T

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

The advanced Tense GKE-63T protection relay with an integrated microprocessor is designed to provide comprehensive protection for electrical equipment and motors against adverse effects in the distribution network. The device continuously monitors network parameters and provides highly accurate protection against overvoltage, undervoltage, current overload, voltage asymmetry, phase loss or phase reversal, and internal overheating. The relay is equipped with an automatic reset function with an adjustable time delay and a memory for recording the last fault status. The compact modular design is intended for easy installation on a standard 35 mm DIN rail.

Main operating modes

• Synchronous mode: three-phase operation – in the event of a fault in one phase, the entire three-phase circuit is switched off.

• Asynchronous mode: independent operation – each phase is monitored and switched off separately (suitable for single-phase loads distributed across three phases).

Technical parameters

• Product type: Digital protection relay (voltage and current)

• Number of phases: 3 (three-phase)

• Rated current (adjustable): 1 – 63 A

• Short-circuit disconnection speed: 0,04 s

• Protection in the event of a neutral conductor (N) interruption: Yes

• Mounting method: 35 mm DIN rail

Adjustment ranges

• Overvoltage protection: 220 – 300 V

• Overvoltage protection: 80 – 210 V

• Voltage asymmetry: 20 – 99 V

• Turn-on delay (Turn-on delay): 1 – 300 s

• Reset delay (Reset delay): 1 – 600 s
