Circuit breakers are an important part of an electrical system. They provide protection against overcurrents, as well as preventing damage to the electrical system in case of a fault. The T21-2-5.00A-01-20A is a type of circuit breaker that is designed for use in a variety of applications, from residential to industrial. In this article, we will discuss the application field and working principle of the T21-2-5.00A-01-20A circuit breaker.

The T21-2-5.00A-01-20A is a two-pole, three-wire circuit breaker that is suitable for use in 60 Hz, 240VAC single-phase and three-phase AC systems. It has a maximum current rating of 5A, and can be used to protect branch circuits, light fixtures, and motors. The circuit breaker is UL and CSA listed, and is suitable for use in the United States and Canada.

The application field of the T21-2-5.00A-01-20A circuit breaker can be divided into two categories: residential and industrial. For residential applications, the circuit breaker is typically used to protect a single branch circuit, either as a main breaker or as a branch circuit breaker. It can be used in circuits supplying lighting, small appliances, and other small loads. In industrial applications, the circuit breaker is often used to protect larger motors, pumps, and other equipment.

The working principle of the T21-2-5.00A-01-20A is relatively simple. It utilizes a bimetallic strip that responds to changes in temperature, in order to open and close the circuit. When the current flowing through the circuit exceeds the rated value of the breaker, the bimetallic strip heats up, which causes it to bend. This bends a spring-loaded lever, which trips the breaker and opens the circuit. When the current returns to normal, the bimetallic strip cools and the lever returns to its original position, thus resetting the breaker.

The T21-2-5.00A-01-20A is a reliable and versatile circuit breaker, and is suitable for use in a variety of electrical systems. It is UL and CSA listed and can be used in both residential and industrial applications. With its simple working principle, the T21-2-5.00A-01-20A can provide reliable circuit protection for a variety of electrical systems.
