On which of the following steps of breaking principle does the arc rotates under the effect of the magnetic field created by the coil?

• 
• 
• 
• 

Which of the following customers is not mentioned as end-users of LF circuit breakers?

• Al Fanar Electrical System, KSA

• Ford, Germany

• San Miguel Brewery, Philippines

• Cement Lafarge, France

It is designed to receive the LF circuit breaker and is composed of several components that ensure safety during racking-in procedure.

• MC Cassette

• RI Stored Energy Operating Mechanism

• Mitop

• Profalux

Among the Evolis product offers, which is provided with a fully autonomous integrated protection chain?

• Evolis Frontal Fixed Version

• EVOset

• LF

• Evolis Lateral Fixed Version

Two techniques can be used to avoid stagnation of hot spots caused by high, localized temperature rise on contacts, or static concentrated arcing. Which technique is used in Evolis circuit breakers?

• Axial Magnetic Field

• Radial Magnetic Field

• Rotational Magnetic Field

• Centripetal Magnetic Field

It gives the device an opening and closing speed that is independent of the operator whether the order is electrical or manual. The electrical control mechanism carries out reclosing cycles and is automatically recharged by a geared motor each time after closing.
