Motor Protection Circuit Breakers (MPCB)

An electromechanical device known as a motor protection circuit breaker, or MPCB, carries out three crucial tasks prior to an electric motor: isolation, motor protection against overload and short circuit, and motor control (on/off).

Category: Product ID: 29821



TeSys GV2 motor circuit breakers provide short circuit protection, overload protection, motor (ON/OFF) control. All functions can work for motors up to 15 KW (GV2RT up to 11 kW) in a 45 mm frame.


  • Thermal-magnetic protection
  • Operation with push button
  • Standard breaking capacity


  • Thermal-magnetic protection
  • Operation with rotary handle (extended rotary handle as an option)
  • High breaking capacity
  • Fault differentiation (short circuit or thermal trip)


  • Magnetic protection only
  • Operation with rotary handle (extended rotary handle as an option)
  • High breaking capacity


  • Magnetic protection only
  • Operation with toggle
  • Standard breaking capacity


  • Built with high magnetic tripping level, it is highly suitable for high inrush current motors or three phase transformers.
  • Operation with toggle


  • Maximum 15 current ratings to cover from 0.1 A to 32 A motor current with a IP20 level for finger safety.
  • The electrical durability (AC-3/415 V) can reach 100,000 operations as a direct control switch
  • Screw clamp for the connection, GV2 ME has two more choices: lug and spring terminals.
  • Padlockable in all versions.
  • DIN rail mounting or screw fixing
  • Multiple choices for “add-on blocks” and accessories such as: contact blocks, electric trips blocks and limiter blocks.


Complete protection concentrated in a single product

  • Compact (45 mm) and easy to integrate with other control devices
  • Durability for the operation as a switch
  • Easy to select for different ratings with limited references


TeSys GV2 can be used for all type of applications across industry, infrastructure and buildings. Compliant to Motor control and protection, in accordance with standards IEC 60947-2, IEC 60947-4-1 and UL 60947-4-1 (transition from UL 508).

GV2RT can be used to protect motors with high current peak on starting or transformer protection.
