Huyu Molded Case Circuit Breakers (MCCB)

Superior Molded Case Circuit Breakers

MCCBs (molded case circuit breakers) from Huyu Philippines provide protection for the circuit and equipment. They are solutions designed for common issues in the Philippines related to the power distribution circuit such as overload, short circuit, and under-voltage condition. They can also provide the protection needed when it comes to the same problems found in the non-frequent start of the motor.

These superior molded case circuit breakers are also in accordance with GB/T 14048.2 and IEC 60947-2 standards.
