63A Adjustable Overvoltage and Undercurrent Protector Relay with Display
Protect a single-phase water pump from damaging current and voltage conditions while keeping energy use in view. The DDS238-VAP detects overcurrent when a water tower is full and undercurrent when a pipe runs dry, then disconnects the pump to help reduce water waste and prolonged motor operation.
Use the backlit LCD to check active energy, current, voltage and power at a glance. Choose automatic or manual reclosing, and set the power-on delay and pump recycle time to suit your pump routine.
Benefits & tips
- Dry-pipe detection: Undercurrent protection can disconnect the pump when a pipe runs dry.
- Adjustable limits: Set overvoltage protection from 85–300 V and overcurrent protection from 1–63 A.
- Flexible restart: Select auto or manual reclosing and adjust the switch-on delay after power-off.
