China CBRB7 Miniature Circuit Breaker (MCB) - Reliable Overload & Short-Circuit Protection from Leading Suppliers & Factory

One of the key features of the CBRB7 Miniature Circuit Breaker is its operational temperature range, which spans from -5℃ to +40℃. This wide temperature tolerance allows the MCB to function effectively in diverse environments, from residential settings to industrial applications. Additionally, the device is designed to operate at altitudes of up to 2000 meters, making it versatile for use in different geographical locations. The ability to withstand relative humidity levels of up to 95% further enhances its adaptability, ensuring that it can perform reliably even in challenging conditions.

The CBRB7 MCB is installed on a standard TH35mm DIN rail, which simplifies the installation process and ensures compatibility with existing electrical systems. This design feature not only facilitates easy mounting but also promotes efficient use of space within electrical panels. Compliance with international standards such as IEC60947-3 and GB14048.3 underscores the product’s reliability and safety, assuring users that it meets stringent quality requirements.

In terms of performance, the CBRB7 Miniature Circuit Breaker boasts a short-time withstand current rating of 24In for 1 second, which indicates its capability to handle temporary overloads without tripping. The mechanical durability is rated at 10,000 operations, ensuring long-term reliability for both residential and commercial applications.

The shell material is composed of a mineral-based material, which contributes to its overall strength and resilience. This material choice meets the flame retardant grade of V0, providing an additional layer of safety in the event of a fire.
