Question 313Electricity & Electronics - QMED
70% to passWhich of the following statements is true concerning the motor controller circuit shown in the illustration? Illustration EL-0004
AThe controller is configured for reduced voltage starting.
BThe controller is configured for use with a three phase reversible squirrel-cage induction motor.
CThe controller is configured for use with a three phase non-reversible squirrel-cage induction motor.
DThe controller is configured for low voltage release.
AI Explanation
The correct answer is C) The controller is configured for use with a three phase non-reversible squirrel-cage induction motor. This is correct because the illustration shows a motor controller circuit that has the necessary components to operate a three-phase, non-reversible squirrel-cage induction motor. These motors are commonly used in marine applications due to their ruggedness and reliability. The other options are incorrect because: A) Reduced voltage starting is not indicated in the circuit, B) The controller is not configured for a reversible motor, and D) Low voltage release is not a feature of this particular motor controller design.
