Circuit Breakers are used to protect any electrical system from overload and short circuit. The 8345-B03B-T3M1-DB1B2B-20A is a common circuit breaker made by Siemens, designed to protect residential and commercial installations. It protects against overloads and short circuits caused by phase failure, insulation breaks, or ground faults. It can also be used to provide emergency shut-off protection during a power failure.

The 8345-B03B-T3M1-DB1B2B-20A circuit breaker uses an electromechanical design which allows it to switch power off rapidly in response to overload or fault conditions, thus providing protection against the resulting excess heat, fire, and electric shock. It also offers superior current-limiting protection and has a modular design for ease of installation and maintenance.

The 8345-B03B-T3M1-DB1B2B-20A circuit breaker is best suited for applications with single or two-pole circuits operating in either AC or DC circuits. It is suitable for use in household, residential, commercial, and industrial applications. It can also be used in applications with up to three poles and is rated up to 60A.

The working principle of the 8345-B03B-T3M1-DB1B2B-20A circuit breaker is based on a bimetallic strip. The bimetallic strip consists of two different types of metal bonded together. When heated by the flow of excess current, the bimetallic strip warps due to differential thermal expansion, leading to opening of the breaker contacts thus switching off the power.

The 8345-B03B-T3M1-DB1B2B-20A circuit breaker also features an adjustable trip setting which allows the unit to be adjusted in order to match the required protection level. Depending on the application, the user can set the breaker to trip in response to both the current and the time that the circuit is in an overload condition. This feature enables the appropriate level of protection to be used for any particular installation.

In addition to the bimetallic strip, the 8345-B03B-T3M1-DB1B2B-20A circuit breaker uses a set of contacts which move to open or close the breaker\'s internal contact points. The contacts are usually made from plastic or copper/silver alloy, and they move in a straight line using a spring-loaded system. If the circuit is overloaded, the contact points break and the power is shut off.

The 8345-B03B-T3M1-DB1B2B-20A circuit breaker is an essential part of any system designed to protect against electrical overload and failure, and is widely used in all kinds of residential, commercial, and industrial applications. It is a reliable, cost-effective, and simple to install and maintain system, making it an ideal choice for any installation.
