Circuit breakers are safety devices designed to protect circuits from shorts or overloads which might cause fire. The 4435.0347 is such a device, with an adjustable trip curve that is ideal for low-voltage power circuits. Here, we will take a closer look at how the 4435.0347 works and its applications.

What is the 4435.0347?

The 4435.0347 is an adjustable trip curve device that offers precision over current protection for low voltage circuits. It incorporates a micro-controller that allows trips to be adjusted with ease to reduce the risk of overloads and shorts. The device also offers the benefit of active current monitoring which monitors current flow and can trip at precise times, as and when necessary.

Applications of the 4435.0347

The 4435.0347 has a wide range of applications and is suitable for use in a range of low voltage power systems. These include motor systems, LED lighting systems, uninterruptible power supplies, DC-DC converters, and many other industrial and consumer applications. It is also suitable for use in residential power distribution systems.

One of its most common applications is in automotive systems. Here, it can be used to detect when a car battery is being overcharged and, should this occur, to shut off the power source in order to prevent any damage to the battery or system. The device is also used in industrial applications such as furnaces, boilers, and factory automation systems.

Working Principle of the 4435.0347

The 4435.0347 utilizes a combination of current sensing and active monitoring to provide precise over-current protection. Its microcontroller is programmed to continuously monitor the level of current flowing through the circuit. If the current reaches or exceeds a predetermined level, the circuit breaker will trip, isolating the circuit from the mains.

The trip point can be adjusted depending on requirements. This can be done by either adjusting a potentiometer or providing an external signal. In the case of adjustable time lag or multi-stage current trip, the external signal can be provided by a relay or timer.

The device is also equipped with thermal protection, which trips the circuit breaker should the device reach its maximum temperature limit. To reset the circuit breaker, the user simply presses the reset button after the fault has been cleared.

Conclusion

The 4435.0347 is a versatile device designed to protect low voltage circuits from shorts or overloads. It can be used in a variety of applications, from automotive systems to industrial processes. Its adjustable trip curve and active monitoring capabilities allow for precise over-current protection.
