Features

Single-phase current relay, window type

These single-phase current relays monitor over- and undercurrents. Manual resetting and automatic resetting are supported by one relay. The start-up lock and operating time can be set separately. The relay warning status is easily monitored with the LED indicator.

  • Single-phase current window relay
  • In 22.5 mm wide industrial housing
  • Under and over control
  • Supply voltages: 24 VAC/DC, 100 to 240 VAC
  • Easy wiring with ferrules
