Motor and Pump protection relay against over underload and phase loss

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).
