T21-2-2.00A-01-20

A circuit breaker is an automated electrical device used as a safety feature for preventing electric circuits from being damaged or destroyed by excessive current. It does this by quickly disconnecting the electric current from the circuit when it detects an abnormally high voltage. The T21-2-2.00A-01-20 is a two-pole type circuit breaker with a rated current of 2A. This makes it a great choice for a wide range of applications, including home wiring circuits, small industrial and commercial installations, and even electrical loads in outdoor applications such as RVs and boats. It is also suitable for use in low voltage circuits, such as those commonly found in 12V automotive systems.

The T21-2-2.00A-01-20 works by detecting when the current of an electric circuit reaches an abnormally high level through internal sensors. When it does, it quickly trips the circuit breaker and shuts off the electric current before any further damage can be done to the electrical system. This type of circuit breaker is designed to be reset after it trips, allowing the system to be brought back online.

The application field of the T21-2-2.00A-01-20 is wide, but it is primarily designed for use in low voltage systems and circuits with a current rating of up to 2A. As such, it is perfect for use in residential, commercial and industrial applications, as well as for use outdoors in RVs and boats, where it can help to protect the electrical system from overloaded circuits and sudden spikes in voltage.

In terms of its working principle, the T21-2-2.00A-01-20 uses a bimetallic switch to detect a high-voltage trip and quickly shut off the current. A bimetallic switch consists of two metal strips that are connected to each other and are heated when a current passes through them. When the current reaches a certain level, the metal strips expand at different rates, causing the switch to trip and open the circuit. The T21-2-2.00A-01-20 also features a thermal element, which senses persistent high current and shuts down the circuit for additional protection.

The T21-2-2.00A-01-20 is an excellent option for a wide range of applications, from small residential lighting circuits to larger industrial and outdoor electrical systems. Its low voltage rating and 2A trip current makes it suitable for a variety of uses, and its simple bimetallic switch ensures reliable operation. Its thermal element also offers additional protection against continuous high currents, making it a great choice for any application where safety and reliability are key.
