Product Overview<\/h2>\n

The CQB2H-63 series miniature circuit breaker is designed by CHAC Electric for distribution protection in AC 50Hz (or 60Hz) systems with a rated voltage of 230\/400V and a rated current up to 63A. With a rated short-circuit breaking capacity of up to 10000A, it provides reliable protection for electrical distribution lines against overload and short-circuit faults. The breaker also features isolation protection and can be used for infrequent connection, disconnection, and switching of circuits. It is widely applicable in terminal distribution scenarios across various industries such as construction, new energy, power, and infrastructure. Our CQB2H-63 series combines advanced technology with strict quality control to ensure long-term reliability and durability, making it an ideal choice for a broad range of electrical protection applications.<\/p>\n
