IULK2-1REC4-35249-50

IULK2-1REC4-35249-50 circuit breakers are a type of protective device specifically designed to automatically shut off power in the event of an overload or short circuit. They are used to protect an electrical system from becoming damaged by an overload of current or by a short circuit. In order for the circuit breaker to function correctly, it is important to understand its components, application fields, and operating principle.

Components

IULK2-1REC4-35249-50 circuit breakers consist of a transformer, a trip coil, a thermal bimetallic, an insulating case, and an operating handle. The transformer is responsible for transforming the input voltage to a level of power suitable for the circuit breaker. The trip coil is the main component that detects the current overload or short circuit, and it is connected to a thermal bimetallic strip. The thermal bimetallic strip comprises two dissimilar metals that expand or contract at different rates when heated. When an overload or short circuit is detected, the trip coil energizes the thermal bimetallic strip, which then causes the operating handle to open the circuit breaker. The insulated case is designed to protect the components from external factors such as dust and moisture.

Application Fields

IULK2-1REC4-35249-50 circuit breakers are commonly used in residential, commercial, and industrial applications. They can be used to protect household electrical systems against overloads, short circuits, and power surges, as well as to protect motors, heavy machinery, and other power-sensitive equipment from damage. Circuit breakers are also used in airplanes to protect the electrical system from sudden voltage changes, as well as to shut off power in a hazardous area.

Working Principle

The basic working principle of IULK2-1REC4-35249-50 circuit breakers is fairly straightforward. When the electric current passing through the circuit exceeds the rated current, the trip coil energizes the thermal bimetallic strip, which expands and contracts, causing the operating handle to open the circuit breaker. This in turn creates an open circuit and the power is shut off immediately. Similarly, when a short circuit occurs, the trip coil energizes the thermal bimetallic strip, which contracts and expands rapidly enough to cause the operating handle to open the circuit breaker, thus creating an open circuit and interrupting the power supply.

Conclusion

IULK2-1REC4-35249-50 circuit breakers are essential components in any electrical system, as they can provide protection against an overload or short circuit. They are typically used in residential, commercial, and industrial applications, as well as in airplanes, to protect the electrical system from sudden voltage changes, as well as to shut off power in a hazardous area. Understanding the components, application fields, and working principles of the circuit breaker can help ensure long-term use and reliable protection.
