Question

It is a type of relay:

• A. H.P. cutout
• B. L.P. cutout
• C. Motor
• D. Hot wire

Hint:

H.P. and L.P. cutouts protect compressors by working like automatic switches.

Answer 1

The Correct Option is A

Relays are protective devices that open or close circuits automatically when certain conditions occur.
An H.P. cutout (High Pressure cutout) is a relay that disconnects the compressor if the pressure goes above safe limits.
Similarly, an L.P. cutout (Low Pressure cutout) is also a relay for low-pressure protection.
A motor is not a relay; it’s an electric machine that converts electrical energy into mechanical motion.
A hot wire is used in other applications but is not a relay by itself.
Therefore, H.P. cutout is correctly classified as a relay.
