Glossary of Terms VII

Question 1

In Line of Duty

Answer 1

An electrical overload device that senses excessive current flow and directly disconnects the load device in the same circuit

Question 2

Magnetic Overload

Answer 2

An electrical device that converts excessive ampere draw into magnetism to open a set of normally closed contacts to protect a load. (Pilot Duty)

Question 3

Magnetic Starter (Motor Starter)

Answer 3

A contactor with built-in overload devices

Question 4

Overload

Answer 4

A device used to detect excessive ampere draw of an electrical load that breaks the circuit to protect the load device

Question 5

Pilot Duty

Answer 5

An electrical overload device that indirectly disconnects the load device through an electrical device that is capable of carrying the load, when sensing high current flow

Question 6

Reset

Answer 6

To return a control or overload to its original position

Question 7

Snap Disc

Answer 7

Inline overload device consisting of a bimetal disc that pops open with excessive current

Question 8

Thermal Overload

Answer 8

An electrical device that converts excessive ampere draw into temperature to open a set of normally closed contacts to protect a load (pilot duty or inline)

Question 9
