Global motor protection circuit breakers market by thermal protection

Thermal protection type motor protection circuit breakers held 48% of the overall global motor protection circuit breakers market in 2016. Thermal protection type motor protection circuit breakers are used for electric current overload protection. These devices are based on an expanding and contracting contact that disconnects motor when excessive current is detected. In the case of high inrush current, when a motor starts, thermal protection delays the response. However, if motor does not start, thermal protection trips in response to extended inrush current.

According to Sushmit Chakraborty, a lead automation research analyst at Technavio, “The shutting down of an electric motor due to tripping of thermal limit is preferable than replacing the damaged motor due to overheating and breakdown. This feature of thermal protection type motor protection circuit breakers not only ensures the safety of related machines but also enhances the life of motors. These features are expected to drive the growth of the global motor protection circuit breakers market by thermal protection during the forecast period.”

Global motor protection circuit breakers market by magnetic protection

Magnetic protection type of motor protection circuit breakers is used during a short circuit, line fault, or a high current electric fault. Magnetic protection, unlike thermal protection, instantly disconnects the dangerous fault currents. These type of electrical circuit breakers use the principle of electromagnetism to break the circuit. If the current passing through the circuit increases, the electromagnetic force increases, and the contact is dragged away.

The usage of magnetic protection circuit breakers is more in discrete industries as compared with process industries. Discrete industries deploy more electrical and electronic equipment, which have their own magnetic fields. These magnetic fields serve as a disruption for the adjoining motors and might even lead to breakage. Interference in the magnetic field may result in disruption of motor circuit, resulting in fault or breakdown. This factor is responsible for high adoption rate of magnetic protection type circuit breakers in the discrete industry.

Global motor protection circuit breakers market by thermal-magnetic protection

Thermal-magnetic motor protection circuit breakers are a combination of both electrical and thermal type of motor protection circuit breakers. They use heat as well as magnetic capabilities to break the circuit. In this motor protection, a latching bimetal is combined with a magnetic coil to ensure protection and isolation.

“Thermal-magnetic motor protection circuit breakers are used for telecommunications, and industrial applications, which require high precision and process control applications. The preference for thermal-magnetic motor protection circuit breakers is expected to increase globally during the forecast period because it does the work of both thermal and magnetic motor protection circuit breakers,” says Sushmit.

The top vendors highlighted by Technavio’s market research analysts in the global motor protection circuit breakers market are:

  • Eaton
  • General Electric
  • Rockwell Automation
  • Schneider Electric
  • Siemens
