E-009 Circuit Protection Devices: 3 PDH
Description of the Circuit Protection Devices course
The Circuit Protection Devices online PDH course is a part of the Electrical Engineering category of courses. This course will introduce you to circuit protection devices used to limit the current or open the circuit in fault condition. The conditions that requires circuit protection are direct shorts (or short circuit), excessive current, and excessive heat.
The two types of circuit protection devices discussed in this course are Fuses and Circuit Breakers.
A Fuse is the simplest circuit protection device based on copper wire connection sized to carry nominal current rating. Excessive current will melt “fuse link” and protect circuit. Fuse will need to be replaced after opening the circuit. Once the problem that caused the increased current is solved, a new fuse must be installed in the circuit.
Circuit Breaker is the mechanical device that will open circuit when current exceeds nominal listed value. Circuit breaker is safe, reliable and tamper proof device that is resettable and can operate multiple times without replacing any parts.
After completion of this course you will have a basic understanding of the Circuit Protection Devices: Fuses and Circuit Breakers.
This course is intended for electrical engineers and other professional engineers interesting in general knowledge of electrical circuitry.
At the end of the course, you will be able to:
- Identify the reasons for circuit protection.
- Identify types of circuit protection.
- List the categories of fuse time delay rating and state a use for each type.
- List the methods of checking for an open fuse.
- Select appropriate type of fuse replacement.
- List the five main components of the circuit breaker.
- Describe circuit breaker tripping mechanism.
- List time delay rating of the circuit breaker.
- List the steps to follow before circuit breaker maintenance.

Length of the Course / Activity
This course is intended to be studied at self-pace and it should take on average of 3 hours to read and be able to comprehend the material to successfully past the online quiz.
To receive the certificate of completion for the above 3 PDH online course, you will need to take a 15-question multiple choice quiz based on the reference material supplied and pass with minimum score of 70%. There is no time limit for the quiz and it can be taken multiple times until a passing score of 70% is achieved.
Certificate of Completion
Once you achieve a passing score of 70% on the quiz you will receive and be able to print your Certificate of Completion as a record of your continuing education. PDH Star will keep a record of your certificate for the duration as required by your state of licensure. You will be able to log on to your account and view and print your past Certificate of Completion.
