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
