1P18U1/21 is a control and proection device designed to be used with power systems and electronic equipment. It is a two-in-one combination switch and circuit breaker, designed to protect both load-side and line-side circuits from over voltage and over current. The device has many features and is simple to operate.

Application Field:

The 1P18U1/21 is generally used in applications that require multiple protection functions, such as data communications, consumer electronics, and industrial equipment. It can also be used for machine tools and other industrial equipment, and any industrial application where surge or circuit protection is needed. The 1P18U1/21 is also suitable for residential and commercial applications.

Working Principle:

The 1P18U1/21 operates by combining a circuit breaker and switch into one device, allowing it to provide both over-current and over-voltage protection. When a potential overload situation is detected, the circuit breaker will trip, preventing the load from being overloaded. The switch acts as a safety feature that prevents inadvertent energizing of the load when the circuit breaker is open. The 1P18U1/21 also features built in surge protection, so that if a voltage spike is detected it will shut down the circuit to prevent damage to the load.

The 1P18U1/21 is a simple and reliable protection device, designed to provide safe, effective, and reliable protection for both load-side and line-side circuits. Its small size makes it ideal for use in a variety of applications, ensuring that the electrical equipment it is used with operates safely and efficiently.
