Model ECSL41AH AC Current Sensor, 120VAC, Trip Point Adjustable 2 – 20A, Trip Delay 0.150 – 7s, Sensing Delay on Startup 6s



ECS Series Information

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.


Features & Benefits

  • Built-in toroidal current sensing: Eliminates need to install stand-alone current transformer and provides isolation from monitored circuit.
  • Encapsulated: Protects against shock, vibration, and humidity.
  • Adjustable mode, trip point and trip delay: Provides flexibility for use in many applications.
  • 10A, SPDT isolated relay output: Allows control of AC voltage loads.
