Miniature circuit breakers: Mini but mighty.
Miniature circuit breakers (UL 489) are a type of molded case circuit breaker that are used to protect and switch the lowest common distribution voltage in a given electrical system. They have also all but replaced fuses in most home applications since they’re far more efficient and cost effective. While their name might not suggest it, miniature circuit breakers play a large role in both residential and industrial applications. Common uses include residential lighting circuits, industrial kitchen appliances, air conditioners, and more.
Most commonly used in panelboards and load centers, they are more compact than the standard breaker, and like most molded case circuit breakers, they use an effective thermo-magnetic trip mechanisms to protect from both overcurrent situations and electric faults.
Is a miniature circuit breaker right for me?
Miniature circuit breakers can be used across a wide variety of applications since they are available as both plug-in and bolt-on (DIN rail). However, unlike other molded case circuit breakers, mini circuit breakers are not adjustable and are rated much lower (125A and below; other molded case breakers can handle up to 2,500A). Mini circuit breakers are also naturally much smaller, and also tend to be more affordable.
