Motor Starters and Protection Components

Motor starters and protection components from Schneider Electric provide reliable control and protection for a wide range of motors and applications. Our portfolio spans individual motor protection devices—such as motor circuit breakers, thermal overload relays, overcurrent relays, and contactors—through to complete, all-in-one modular solutions that combine multiple functions in a single product.

The basic function of a motor starter is to safely start and stop the connected motor while providing protection against electrical and thermal faults. Unlike standard relays, motor starters integrate overload protection to help prevent damage, reduce downtime, and extend equipment life.

Key motor starter and protection components include:

  • Motor circuit breakers for short-circuit and overload protection
  • Thermal overload relays to guard against excessive current and overheating
  • Overcurrent relays for precise fault detection and response
  • Contactors for reliable motor switching and control
  • Modular, all-in-one starter assemblies that simplify selection and installation

Benefits of Schneider Electric motor starters:

  • Safe, dependable motor starting and stopping—manual or automatic
  • Integrated overload and fault protection to minimise risk of damage
  • Simplified installation and maintenance with modular options
  • Enhanced uptime and equipment longevity through accurate protection
  • Broad compatibility across industrial and commercial applications

Choose Schneider Electric motor starters to streamline motor control, strengthen protection, and improve service continuity across your operations.

What is an enclosed motor starter? Enclosed motor starters are electromechanical switches, comparable to relays. The primary difference between a relay and a starter is that a starter provides overload protection for the motor. With electrically-operated enclosed motor starters, contactors are used for switching the power-carrying conductors. When the coil in the contactor is energised, it produces the electromagnetic field and that pulls the switch contacts. When the coil is de-energised, contacts are pulled back to the normal position by a spring arrangement. How to improve motor starter efficiency? Designing a more energy-efficient motor starter creates cost savings over the lifetime of the equipment. Industrial infrastructures consume more than 31% of the available energy in the world and electrical motors alone represent more than 60% of that energy consumption. The purchase price of a motor also only accounts for 2 to 3% of the overall costs, the remainder of the expense primarily being energy consumption.
