Circuit Breakers: T11-2-25.0A-31976-1 Application Field and Working Principle

The T11-2-25.0A-31976-1 circuit breaker is used in various applications and surroundings, where the reliability and stability of the operating system must be guaranteed.Widely used in the industries of power system, automotive and railway, the T11-2-25.0A-31976-1 circuit breaker is designed to prevent overloads, short-circuits and other abnormal electric situations and helps to protect the electrical system from damages.The working principle of the T11-2-25.0A-31976-1 circuit breaker can be classified into two parts: the mechanical functioning principles and the electrical active principles. The first part is the mechanical functioning principles which includes the spring mechanism and the arc chamber. The spring mechanism is considered as the releasing or snapping mechanism of the circuit breaker. It enables the breaker to momentarily and freely open the electrical contacts while interrupting the current. The spring will be compressed when closed and is released back to its position when open.Meanwhile, the arc chamber is designed to interrupt the electrical arc once the contacts are opened. The arc chamber has the capability to quench the arc rapidly, with decrease of both electric potential and temperature. This could further keep the temperature of the arc chamber within the permissible limits, preventing any possible damages.

The second part is the electrical principles which includesoperation during a short-circuit and operation during an overload. During a short-circuit, the circuit breaker will open the electrical contacts and extinguish the short-circuit arc rapidly by means of metallic bridge element. Simultaneously, the energy absorber will reduce the damage caused by high energy, when the arc chamber contacts are opened. On the other hand, for an overload, the circuit breaker will disconnect the electrical contacts in a period short enough to avoid any electrical fire. It is also important to verify that the magnetic blowout coil failure is avoided during its operation.

To ensure reliable performance and safety of electrical systems, the T11-2-25.0A-31976-1 circuit breaker should be inspected and tested periodically, regardless of its usage. The annual inspection should examine if there are any visible damages and conform to the relevant regulations.

In conclusion, the T11-2-25.0A-31976-1 circuit breaker is designed to protect the electrical system from overloads and short-circuits. It operates according to mechanical and electrical principles, where the spring mechanism and arc chamber ensure the reliable performance and safety of the system. Furthermore, proper maintenance and periodic testing are essential to ensure a safe and optimal performance of the breaker.
