C63 Miniature Circuit Breaker

The C63 Miniature Circuit Breaker from the XENHO factory is an automatic switching device designed to protect electrical circuits against damage caused by overloads and short circuits. It is capable of rapidly interrupting the current whenever a fault occurs, thereby ensuring the safe and stable operation of the electrical system. Its core value lies not merely in its exceptional technical specifications, but—more importantly—in its silent guardianship of life and property; behind every precise trip, there lies a profound embodiment of reliability and responsibility.

From residential power distribution to industrial control applications, the C63 Miniature Circuit Breaker has earned widespread trust thanks to its compact design and high breaking capacity. Its current range of 6–63A precisely matches diverse load requirements, while breaking performance ranging from 4.5kA to 10kA allows it to confidently handle sudden short-circuit events. Furthermore, the availability of both AC and DC versions ensures compatibility with a wide variety of system configurations. Its fully enclosed insulated structure, combined with shock-proof terminals, significantly enhances safety during installation and maintenance. Whether for new construction projects or equipment upgrades, the C63 remains a reliable choice for circuit protection, establishing a robust line of defense for modern electrical environments.

Core Advantages

As a primary source manufacturer of components, XENHO not only offers competitive pricing but also maintains strict quality control over its C63 Miniature Circuit Breakers right from the initial stages of production.

We offer complete flexibility in component selection, allowing for the independent configuration of internal materials—whether iron, standard copper, or high-purity red copper. Alternatively, customers may specify the housing design while allowing us to independently configure the internal components.

The distinct advantage of working with a primary source manufacturer lies in our affordable pricing and extensive range of customization options.

Safety & Protection Features

The C63 Miniature Circuit Breaker features a built-in thermal-magnetic trip unit, implementing a dual-protection mechanism that combines time-delay overload protection with instantaneous short-circuit protection. It precisely detects fault currents and interrupts the circuit within milliseconds.

The terminals feature a touch-proof design, utilizing insulating barriers to effectively prevent arc-flash injuries during wiring operations. The fully enclosed housing boasts a UL94-V0 flame-retardant rating, ensuring that no open flames are generated, even under high-temperature or fault conditions.

DC models feature a specialized magnetic arc-extinguishing system capable of rapidly elongating, cooling, and extinguishing electrical arcs, thereby ensuring the continuous and safe operation of DC systems such as those found in photovoltaic and energy storage applications.

Prior to leaving the factory, every product undergoes 2,000 mechanical endurance tests and high-voltage insulation verification to ensure stable operation for over 100,000 cycles, even under complex operating conditions.
