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 under current events like locked rotor, loss of load, an open heater or lamp load, or proves an operation is taking place, or has ended.

ECS: Selectable over or under current sensing
4: Input 120 VAC
0: Trip Point Adjustable Ranges 0.5 ... 5A
A: Trip Delay Adjustable Ranges 0.150 ... 7s
G: Sensing Delay on Start-up 5 s
