Motor Soft Starter
Motor Soft Starter
Product Code : me 21
Brand Name : MAX Altistart 48
Product Description
Altistart 48 soft starter is a high performance soft starter using 6 thyristors for controlled starting of 3 phase a synchronous squirrel cage induction motors. It provides, Torque Controlled starting & stopping, Electronic thermal overload protection, mechanical protection to driven machine, increased life to mechanical power, transmitting gadgets and driven machinery and also reduced stress on power supply network.

Features

  • Separate set of terminals are integrated to terminate cables going to bypass contactor
  • Even in bypass mode inbuilt Electronic thermal over-load remains in circuit
  • No external CT required for current measurement
