BYB1-63 Micro Circuit Breaker/ Miniature Circuit Breaker(MCB)
The circuit breakers we produce refer to protective devices installed on terminal distribution lines, mainly used for overload and short circuit protection of lines and electrical equipment. In the context of the increasing demand for electricity in national production and daily life, and the society's high requirements for power supply safety and reliability, it is necessary to optimize the operation effect of the distribution network. To achieve this goal, it is necessary to scientifically and reasonably install small circuit breakers on interrupted distribution lines, effectively protect the lines and electrical equipment, and avoid overloading, which may pose certain safety hazards to the lines and electrical equipment.
From styling design to process material selection, we have gone through various designs and polishing to meet the needs of various scenarios. The shell is heat-resistant and cold resistant, and can still operate normally in harsh environments. In terms of operation, we can achieve instant power outage, using our strength to protect the normal operation of homes and businesses, making your electricity use more reassuring!
