Sipariş No : 3 Phase Panels – CBT

The cosine of phi (cos φ) is the value of the cosine of the phase angle between the voltage and the intensity of the electrical current. This oscillates from a value slightly below 1 for a full load operating motor to almost 0 when it is dry running.

WITHOUT LEVEL SENSORS
 
Main Advantages:
 
  • Thermal memory that memorises heating and cooling cycles of the motor.
  • Automatic reset for well filling and adjustable from 2 to 75 minutes.
  • Indication of tripping cause.
  • Control point for pressure switch, buoy, programmer…
  • Includes: circuit breaker 3P or 3P+N, PF electronic relay, contactor, LED’s and on/off switch.
  • Models with a metal case also include voltmeter, ammeter and cos φ meter.
Protection Functions
 
  • Dry running by monitoring cos φ
  • OVerload with thermal memory
  • Phase loss / imbalance
  • Incorrect phase sequence
