TDP-4 voltage and overcurrent relays

Name: TDP-4 voltage and overcurrent relays
Brand: TOSUNLUX

TDP-4 1P 32–80 A · TDP-4 3P 63 / 80 A

IEC 60947-1

TOSUNLUX (Tosun) modular digital voltage and current protectors with motorised disconnection: automatic disconnection in the event of overvoltage, undervoltage or overcurrent, automatic reconnection 1 to 2 minutes after a return to normal. Voltage and current displays on the front panel. TDP-4 single-phase 220 V (32 to 80 A) and three-phase 380 V (63 / 80 A).
