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.
