ECS Series Information

  • Selectable over or under current sensing
  • Toroidal through hole wiring
  • 0.5 ‑ 50A trip points
  • Adjustable or factory fixed trip delays
  • Isolated, 10A, SPDT output contacts
  • 5% trip point hysteresis (dead band)
The ECS Series of single‑phase AC current sensors is a universal, overcurrent or undercurrent sensing control. Its built‑in toroidal sensor eliminates the inconvenience of installing a stand‑alone current transformer. Includes onboard adjustments for current sensing mode, trip point, and trip delay. Detects over or undercurrent events like; locked rotor, loss of load, an open heater or lamp load, or proves an operation is taking place or has ended.
