AI Explanation
The correct answer is B) Combination starter.
A combination starter is the proper name for the entire device shown in the illustration EL-0181. It includes all the necessary subassemblies, such as a magnetic contactor, overload relay, and a disconnecting means, to provide complete motor control and protection.
The other options are incorrect because:
A) A safety disconnect switch is a separate component that isolates the power supply, not the complete motor control assembly.
C) A magnetic contactor is a single component within the combination starter, not the entire device.
D) A magnetic starter is an older term that refers to the same type of device as a combination starter.
