249-4-28269-3

A circuit breaker is a device that is designed to interrupt the flow of electricity in an electrical circuit in the event of an overcurrent. It usually has three primary components: a contacts system, trip unit, and power module. The 249-4-28269-3 circuit breaker is an industrial grade circuit breaker that works off of the same principles as other circuit breakers, providing a reliable way to safeguard circuits from damage due to overcurrents.

The 249-4-28269-3 circuit breaker is designed for applications that require safety and protection from a wide variety of potential overcurrents. This includes industrial, manufacturing, and commercial facilities that require a reliable way to protect from load fluctuations or unusually high electrical currents. The circuit breaker itself is a three-phase breaker with 380V rated voltage, a maximum rated current of 35A, and a short-circuit breaking capacity of 10kA.

The working principle of the 249-4-28269-3 circuit breaker is quite simple. When an overcurrent is detected in an electrical circuit, the contacts of the circuit breaker open and an impulse is created which trips the trip unit. This releases the mechanical latches that are holding the contacts in place, thus breaking the flow of electricity. The power module then kicks in and powers down the circuit to bring it back within safe operating levels.

In order to ensure the safety of the circuit, the 249-4-28269-3 has several features that help to reduce the risk of overcurrents. One of these is an adjustable contact gap. This can be lengthened or shortened according to the type of load and the amperage of the current. This ensures that the contacts are not too wide open or too tight, which can lead to arcing or a short circuit. Additionally, the circuit breaker also features an automatic, self-adjusting release mechanism and a highly reliable mechanical latch system.

Another important feature of the 249-4-28269-3 circuit breaker is the built-in thermal overload protection. This helps to protect the circuit from thermal overloads or excessive temperatures which could lead to damage to the circuit. This thermal protection is provided by a thermostat which can detect changes in temperature and initiate the response of the trip unit.

Overall, the 249-4-28269-3 circuit breaker is an effective and reliable way to protect electrical circuits from potential damage due to overcurrents. It is designed for industrial, commercial, and manufacturing applications and provides a safe and secure way to protect from potential overcurrents. The adjustable contact gap, self-adjusting release mechanism, reliable mechanical latch system, and built-in thermal protection provide an additional layer of safety for the circuit.
