MCCB

In industrial power systems, stable and reliable circuit protection is the core element to ensure production continuity and equipment safety. Our Industrial Standard MCCB (Industrial Standard Molded Case Circuit Breaker) has become the preferred protection device in heavy industry, manufacturing, energy facilities and other fields with its excellent performance and rugged design. The product rated current covers 16A to 1600A, and the breaking capacity is up to 150kA. It complies with international standards such as IEC 60947-2 and GB 14048.2. It has complete overload, short circuit and undervoltage protection functions, providing a full range of safety barriers for various industrial power distribution systems.

Industrial Standard MCCB adopts innovative arc extinguishing technology and high temperature resistant materials, and can still maintain stable performance under extreme working conditions. The unique double breakpoint design increases the breaking speed by 40% and effectively suppresses the generation of arcs; the modular structure supports the free combination of various trip units such as thermal magnetic and electronic types to meet different application scenarios such as motor protection and transformer protection. The product shell is made of high-strength engineering plastic and metal composite material, with a fireproof grade of UL94 V-0 and a protection grade of IP65. It can operate stably in an ambient temperature of -25℃ to +70℃, and is suitable for harsh industrial environments such as metallurgy, mining, and shipping. The humanized operating mechanism provides three-position indication of "close/open/reset" and is equipped with a transparent fault indication window to facilitate rapid troubleshooting of line problems.
