Circuit breakers are a kind of protective device used to prevent an electrical system from overloading. A circuit breaker is an automatic interrupter that is designed to shut off the flow of electricity in an electrical system when the system is overloaded or short-circuited.

The 1B5UM is a type of miniature circuit breaker used to protect loads from over-current. The 1B5UM is typically used in residential and commercial applications. It is UL Listed as a circuit breaker for use in both ordinary and hazardous conditions. It is suitable for a variety of voltage and current ratings, from 600Vac/100A to 600Vdc/50A.

The 1B5UM has a relatively simple working principle. It is designed to detect an over-current condition and open the circuit to protect the electrical components. In the event of an overload, the 1B5UM automatically disconnects the load from the circuit, thus preventing further damage from occurring. To reset the circuit breaker, the user simply turns the switch off and then back on.

The 1B5UM is a reliable and robust circuit breaker that is easy to use, simple to install, and has a long life expectancy. It is designed to meet the requirements of UL 489, UL 1077, and CE mark requirements. It is also designed to meet IEC 60898-1 and IEC 60947-2 specifications. Furthermore, the 1B5UM has a short-circuit current rating of up to 100kA, allowing it to provide effective protection against short-circuiting.

The 1B5UM is an ideal choice for applications where circuit protection is required. It can be used in residential, commercial, and industrial applications. It is commonly used in motor control centers, motor power systems, motor control systems, and other applications. Furthermore, the 1B5UM is capable of withstanding temperatures of up to 65°C (149°F).

In summary, the 1B5UM is a reliable, robust, and effective circuit breaker. It is suitable for use in a wide range of applications and can provide effective protection against over-current and short-circuiting. Furthermore, the 1B5UM is simple to install and easy to use, making it an ideal choice for residential, commercial, and industrial applications.
