Manual Motor Starters

A Complete Motor Protection Concept

Manual motor starters, also referred to as motor protection circuit breakers (MPCBs) or manual motor protectors (MMPs), are essential electromechanical devices for main circuit protection. They allow manual ON/OFF switching of motors and provide fuseless protection against short-circuit, overload, and phase failures. This fuseless protection minimizes costs, saves space, and ensures rapid response during short-circuit events by swiftly disconnecting the motor within milliseconds. Starter combinations are configured with contactors and are available with screw or Push-In Spring terminals.

  • Harmonized Accessory Range : Simplifies planning and logistics across the MS1xx and MO1xx families.
  • Reliable Motor Protection : Reduces machine downtime and maintenance costs with dependable protection.
  • Manual ON/OFF Handle : Enables manual control and provides short-circuit current and overload protection.
  • Adjustable Current Settings : Large markings for precise current setting adjustments.
  • Temperature Compensation : upports operation up to +60°C.
  • Remote Control Options : Includes undervoltage release or shunt trip for remote operation.
  • High Short-Circuit Breaking Capacity (Ics) : Up to 100kA ensures robust performance under fault conditions.
  • Suitable for 1-Phase Applications : Versatile application across single-phase systems.
