The compact miniature circuit breaker (MCB) is a versatile electrical protection device designed for various
applications. Its primary functions include ensuring the safety and reliability of electrical circuits by
promptly interrupting the flow of current in the event of overload or short circuit conditions.
With advanced engineering, this MCB offers a reliable and efficient solution for safeguarding electrical systems.
Suitable for a diverse range of electrical installations, the MCB is designed to operate within a specific
electrical range. It is commonly employed in power systems with a frequency of 50 or 60 Hz, featuring
a rated operational voltage (Ue) of 400V or below, and a rated current (Ui) of 63A or below. This makes
it adaptable to a wide array of scenarios, from residential applications to commercial and industrial settings.
The miniature circuit breaker finds its place in various usage scenarios, including office buildings and
residences, where it provides essential protection for lighting circuits, power distribution systems,
and equipment. Its compact size and reliable performance make it particularly suitable for installations
with limited space. Additionally, the MCB excels in preventing overloads and short circuits, ensuring the
longevity and safety of the connected electrical devices.
