Motor and Pump protection relay against over underload and phase loss
- Current range: 1…18A (0…100%: with /5A current transformer)
- Reset: Manual or timer (0…120 minutes)
Motor and Pump protection relay against over underload and phase loss
Electronic motor and water pump protection relay with three function in one relay:
- (1) Overload 1 to 19,2 A. Detection by external current transformer.
- (2) Underload 1 to 19,2 A. Detection by external current transformer.
- (3) Phase failure/loss detection.
- Modular plug-in format (2 modules).
- Power supply: single voltage 230 or 400 Vac (depending on the model).
- Protection of single-phase or three-phase motors.
- Dry running detection application (without probes) in pumps whose consumption varies with underload.
- Overload trip time: 7 s.
- Underload trip time: 4 s (with 20 s starting inhibition).
- Automatic re-start time after underload trip, selectablem and adjustable (up to 2 hours).
- Manual re-start push-button (Reset).
- 3 digits LED display for: measured current, trip current, remaining re-start time, overload alarm, underload alarm and setting values.
- Setting values through thumbwheels with direct visualization on display.
- Trip current is not influenced by environmental temperature.
- Connection for EXTERNAL auxiliary control at 12 Vdc available (pressure switch, float switch, etc).
