Motor protection switches
Motor protection switches are primary circuit electromechanical protective devices. They are primarily used as manual motor switches (on/off) and for fuseless protection against short circuits, overloads, and phase failures. Fuseless protection is a cost-effective choice and requires minimal installation space. Additionally, it ensures rapid response in short-circuit situations by shutting down the motor within milliseconds. Motor starters are typically specified together with contactors.

Benefits
  • Compatible accessories (auxiliary contacts, alarm contacts, under-voltage and undervoltage release units) for MS1xx and MO1xx product lines
  • Compact size and clear markings
  • Motor protection switch combined with a contactor enables a clear starter assembly, design, and installation
  • Products are mechanically compatible and enable electrical and mechanical connection for constructing direct-on-line starters
  • Minimized downtime due to motor protection and reduced fault-finding effort
  • Precisely implemented motor protection helps minimize maintenance costs
Features
  • Manual control / short-circuit and overload protection
  • Adjustable current setting for overload protection and magnetic tripping
  • Disconnection function
  • Temperature compensated
