ANALOGUE STARTER PROTECTOR - 3 PHASE, 380V General Description This three phase control panel is rated for use from 7.5 to 37.5kW, 380V. It will control and protect pump motors in the following capacity: Basic control functions include: 1. Over current and under voltage protection 2. Unit can detect liquid levels at source and in delivery tank/reservoir and react according to parameters. 3. Power will be switched off in the event of power failure or loss of phase.
Technical Information Input Voltage 380 ~ 415V, -5% to +10%, 50Hz Output Power 9.2-37.5kW Water Probe Voltage 24 VAC Operating Temperature -5°C to +40°C Dimensions 300 x 400 x 240mm Level switching Dual level switch capability Reaction time Loss of phase < 2 sec Over load 3-100 sec adjustable
Operation Water level control between two reservoirs or tanks can be performed simultaneously or for any one tank independently. Over load protection: with the loss of a phase, the phase detection CCT will signal for the power contactor to drop out and switch the power supply to the pump motor off. Should the pump motor draw an over current the over current protection CCT will signal the power contactor to disengage and stop power supply to the pump motor. This will be done automatically within the time limits set by the installer. The higher the current overload the faster the switch-off time.
