Circuit breakers are an essential component of any electrical system, and their use is growing rapidly as the world moves to renewable energy sources. The PP21-2-1.20A-OB-V is a type of circuit breaker designed for optimal performance in modern residential and commercial settings. Its features include a compact profile, improved safety features, and a high switching rating.

Circuit breakers are used to detect an overload in the electricity supply, by shutting off the electricity so that the overloaded circuit does not cause an electrical fire. The PP21-2-1.20A-OB-V is designed to be able to not only detect an overload, but also to offer additional safety features. These safety features include an integrated ground-fault circuit interrupter (GFCI) as well as an inverse time delay that provides additional protection against short circuits. This circuit breaker also includes a thermally protected bimetallic trip system to protect the breaker from overheating.

The PP21-2-1.20A-OB-V circuit breaker also has an adjustable current and voltage range, which allows it to be used in various applications. This range includes a voltage range of 100 to 128 volts and an adjustable current range of 0.015 to 1.20A. This allows the breaker to be used in single and multiple-family dwellings, as well as in commercial and industrial applications.

The working principle behind the PP21-2-1.20A-OB-V circuit breaker is relatively simple. When the current in the protected circuit exceeds the pre-determined trip rating, the thermal and bimetallic elements of the breaker begin to heat up. When the temperature reaches a certain limit, the bimetallic element bends and causes the breaker to trip and shut off the current in the circuit.

The PP21-2-1.20A-OB-V circuit breaker is UL tested and approved, making it an ideal choice for residential and commercial settings. Its small profile allows it to be installed in even the most confined spaces, while its safety features make it a reliable and safe choice. The adjustable current and voltage range also makes it a great choice for a wide range of applications, while its thermal and bimetallic trip system offers protection against overheating.
