Pump protection relay

• The Electro 11 pin plug-in range of control and timing devices are to be installed into a standard 11 pin base making installation easy and convenient.
• Microprocessor based pump protection relay capable of protecting a submersible pump against all major power line faults.
• The unit calibrates itself under normal running conditions and stores these parameters in non-volatile memory.
• The unit also incorporates a reset delay for under current situations to enable the borehole to replenish itself.
• In an over current situation the unit will retry three times to prevent permanent tripping with temporary blockages.

Features:

• Microprocessor based protection relay
• Over / under current protection
• Over / under voltage protection
• Selectable under current reset delay
• Three retries for over current
• Automatic self diagnosis of pump
• Led indication for all faults
