LV ABB MOTOR BREAKER

A complete motor protection concept

Manual motor starters are electromechanical protection devices for the main circuit. They are used mainly to switch motors manually ON/OFF and to provide fuse less protection against short-circuit, overload and phase failures. Fuse less protection saves costs, space and ensures a quick reaction under short-circuit condition by switching off the motor within milliseconds. Starter combinations are setup together with contactors.

 

Main benefits

  • Harmonized main accessory range (auxiliary contacts, signal contacts, shunt trips and undervoltage releases) for MS1xx and MO1xx family

  • Compact design
  • Efficient planning and installation perfectly matching the ABB contactor family
  • Simple connecting links ensure electrical and mechanical connection to build direct-on-line starters
  • Less machine downtime by protecting motors and reduced trouble shooting 
  • Reduction of maintenance expenditures by protecting motors

Main features

  • Manual control / short-circuit current and overload protection
  • Adjustable current setting for overload protection and magnetic trip indication
  • Disconnection function
  • Temperature compensation
  • Remote control via undervoltage release or shunt trip
  • Short-circuit service breaking capacity Ics up to 100 kA.
