Low-voltage switchgear is the name typically used for metal-enclosed or metal-clad low-voltage power circuit breaker switchgear rated for 600V alternating current (AC) and below. The metal-enclosed switchgear is completely enclosed on all sides and on top with metal sheets and has stationary primary power circuit switching or interrupting elements, or both, with buses and connections.

The metal-clad low-voltage switchgear has removable circuit breakers which are housed in individual earthed metal compartments. Low-voltage switchgear takes on many specific forms and functions that combine metering, monitoring, control, protection, and distribution. Original equipment manufacturers (OEMs) now provide a wide variety of low-voltage switchgear arrangements, some of them very custom, to meet the user’s requirements.

This course is suitable for electrical engineers with a desire to understand the fundamentals of low voltage switchgear technology. Presented details cover definitions of MCCBs, insulated case circuit breakers, power circuit breakers and fused power circuit breakers. Different monitoring and protection packages are also addressed. Upon successful completion of this course, you will have a solid understanding of low voltage switchgear technology, overcurrent protection mechanisms, selection and application of low voltage equipment, and assessment of low voltage breakers.

Learning Objectives

Upon completion of this course, participants will be able to:

• Identify the operating characteristics of molded-case circuit breakers (MCCBs).
• Differentiate insulated-case circuit breakers from other low-voltage breaker types.
• Explain the function of power circuit breakers in low-voltage switchgear.
• Evaluate overcurrent protective devices and monitoring/protection packages for a stated application.
• Select appropriate low-voltage equipment for a stated system requirement.
• Assess factors that influence the service life of low-voltage breakers.
• Apply endurance requirements when evaluating low-voltage breakers.

Certificate of Completion

You will be able to immediately print a certificate of completion after passing a multiple-choice quiz consisting of 24 questions. CPD credits are not awarded until the course is completed and quiz is passed.
