Advanced pump protection relay The Electro D range of control and timing devices are compact modular units for easy introduction into standard panels and/or distribution boards. They mount directly onto DIN rail and align with standard miniature circuit breakers (MCB’s). Advance pump protection relay to safeguard against damage to borehole pumps. The unit is easily calibrated and then monitors all important pump characteristics. All parameters are saved in non-volatile memory to be available even after power loss. A re-start delay ensures the borehole replenishing before pumping starts again. Features: LED indication for faults Automatic diagnosis of pump Security input to control pump Front face calibration / reset button High current 16A SPST output relay LED indication for power supply ON Modular 35.5mm DIN rail mountable High current sensing input (up to 15A) Monitors over and under voltage/current Under current ( dry running ) restart delay High resolution analogue microprocessor DESCRIPTION Three phase pump protection relay CONTACT 16A SPDT PHASE Three phase RATED CURRENT 10A RATED VOLTAGE 250V MECHANICAL LIFE 10×106 cycles PROTECTION INDEX IP IP 20 OPERATING TEMPERATURE -10 to + 50°C STORAGE TEMPERATURE -50 to + 85°C DIMENSIONS (MM) (H) 92 x (W) 36 x (D) 64
