A circuit breaker, or CB, is a device used to interrupt an electricity supply and prevent the lines or circuits from becoming overloaded or hazardous. Circuit breakers are essential pieces of electrical equipment, providing protection for both the consumer and the public grid. The 991308 model of circuit breaker is a bimetallic stamped, thermal-magnetic, and multipole breaker designed for use in low voltage industrial and commercial applications.

The 991308 model of circuit breaker uses a bimetallic element with an upper temperature cutoff set at 80°C, and a lower temperature cutoff set at 65°C. This design allows the 991308 model to produce a consistent trip rating, regardless of the ambient temperature. When the current traveling through the breaker is low, the temperature of the bimetallic element remains below the minimum temperature, and the breaker remains closed.However, as the current passing through the breaker increases, the temperature of the bimetallic element rises to the maximum temperature, which triggers the circuit breaker to trip. This thermal-magnetic design helps protect circuits from short circuits or overloads. Additionally, this design allows for easy installation, as the same breaker can be used in a variety of applications without requiring different trip ratings.

The 991308 circuit breaker also features a multipole design, which means it can be used with one contact or multiple contacts depending on the application. This design allows for a greater range of applications. The 991308 circuit breaker is also designed for use in applications with intermediate current ratings, with current ratings ranging from 15A to 60A. This allows for flexibility in application, as a single trip rating can be used for circuits with multiple current ratings.

The 991308 circuit breaker is designed for use in low voltage applications such as residential, commercial, and industrial applications. It is especially well-suited for applications where a fast response and high safety rating are required. Additionally, the 991308 circuit breaker is UL Listed and CSA Certified, meaning it is up to all the latest safety standards. It is a reliable and cost effective solution for a variety of applications.

In conclusion, the 991308 circuit breaker is a reliable and cost effective solution for a variety of low voltage applications. Its bimetallic and thermal-magnetic design helps protect circuits from short circuits and overloads, while its multipole design allows for flexibility in application. Furthermore, it is UL Listed and CSA Certified, meaning it is up to all the latest safety standards. With its fast response and high safety rating, the 991308 model is an excellent choice for a wide range of applications.
