ECSTD Series Information

  • Adjustable Start‑Up/Delay Time from 0‑15 seconts to eliminte alarms due to start‑up inrush
  • Choice of N.O./N.C. AC or Universal Outputs
  • Improved of Installation and Use
  • Industrial Grade Performance
  • UL Approved

The CurrentWatch ECSTD Series from Eaton's electrical business is a family of high performance current‑opperated switches with a field‑adjustable time delay to help minimize nuisance trips during start‑up and operation. Designed for motor status applications where setpoint accuracy and repeatability are critical, the ECSTD Series offers a linear setpoint characteristic and constant hysteresis. Standard features include self‑powering, jumper‑selectable ranges and a choice of outputs and housing styles.

Typical Applications
  • Motor Protection‑ Serves as an electronic proof‑of‑operation; detects current draw changes in motors when they encounter problems such as pumps running dry or pending bearing failure; non‑intrusive and less expensive to install than differential pressure flow sensors or thermal switches; much quicker response time than Class 10 overload relays
  • High Inrush or Temporary Overload Current‑ Adjustable start‑up/delay timer allows 0‑15 seconds to eliminate nuisance trips from high inrush or short overload conditions
