A 1BU20R circuit breaker is an electric switch used to protect an electrical circuit from damage caused by overloads or short circuits. It is typically used in the protection of hazardous electric components, such as motors, generators, transformers and circuit boards. The 1BU20R circuit breaker is designed to automatically open or close a circuit when a certain amount of current is exceeded. This allows the circuit breaker to serve as a switch and protect the electrical system from damage.

The 1BU20R circuit breaker was designed for use in industrial, commercial, and residential applications. It has been tested and approved by Underwriters Laboratories Inc. (UL) for safety and reliability. The 1BU20R has a wide range of ampere ratings ranging from 0.2A to 20A. It also has an adjustable trip point that can be adjusted to ensure the desired trip current level is reached. The 1BU20R is also UL listed for operating at a temperature range of -40°C to 80°C.

The 1BU20R circuit breaker is an automatic trip device that uses a bimetal strip to detect an overload or short circuit. The bimetal strip is designed to bend when it is heated by an overload current. The bending action then opens or closes the circuit breaker contacts, depending on the type of trip. The trip setting can be adjusted to ensure the circuit breaker trips at the specified current level.

The 1BU20R circuit breaker also features an auxiliary contact, which can be used to activate external alarms or control relays. This is typically used for remote monitoring of the circuit breaker. The 1BU20R also has a manual reset button, which can be used to reset the circuit breaker after an overload or short circuit. This is a useful feature when testing electrical circuits or troubleshooting.

The 1BU20R circuit breaker is an effective and reliable way to protect electrical circuits from damage. It can be easily installed in industrial, commercial, and residential applications and is UL listed for safety and reliability. Its adjustable trip point and auxiliary contact make it a great choice for applications that require remote monitoring or alarms. Furthermore, its manual reset button is a useful feature for when electrical circuits need to be tested or troubleshooted. With its reliable performance and robust design, the 1BU20R circuit breaker is an excellent choice for applications that need reliable circuit protection.
