G3PF

Features

“Intelligent” SSR with Built-in current transformer which enables Heater Burnout and SSR Shortcircuit Failure Detection.

The G3PF quickly detects heater burnout and SSR short-circuit failure, and information is provided to let you know which problem has occurred, which is ideal for applications where down time must be minimized.

  • Built-in Current Transformer (CT) helps reduce wiring steps.
  • Detects the burnout of any one of a group of heaters.
  • Detects the burnout of 3-phase heaters.
  • Detects SSR short-circuit failures.
  • Error detection level can be easily set with a switch.
  • Zero cross function.
  • Operation indicator.
