Circuit breakers play an important role in the safe and reliable operation of electrical and mechanical systems. They are a key element of the electrical protection system in any building, industrial plant, or electrical system, providing fast and reliable automatic protection against electrical overloads or short circuits. The IELBXK11-1REC5-70044-55-C is one of the most popular circuit breakers available today. This article will discuss the application field and working principle of this specific model.

Application Field

The IELBXK11-1REC5-70044-55-C is designed to be used in residential and light commercial installations, as well as in industrial power circuit protection. It is suitable for use in single-, two-, and three-phase applications up to 4,000 volts and 65,000 amperes. It is also suitable for use in low energy demand applications, as well as in high energy demand applications. The IELBXK11-1REC5-70044-55-C is available in both standard and thermally protected versions, and is designed for use in power distributions, load centers, panel boards, control panels, and motor control centers.

The IELBXK11-1REC5-70044-55-C is UL listed for 120, 240V residential applications, and also meets the requirements of NEC and CEC, as well as UL 1618 ratings for general purpose and special appliance applications. It is also listed as a No.1 circuit breaker for use in power centers and Cailux®Flexible AC Conduit systems. In addition, it meets the requirements of Section 17.48.2 of the OSHA standard.

Working Principle

The IELBXK11-1REC5-70044-55-C circuit breaker is designed to trip on overloads or short circuits, providing fast and reliable automatic protection against electrical overloads or short circuits. This is accomplished through the use of a current-sensing element that monitors the current flowing through the circuit. When the current exceeds the breaker’s pre-set settings, it trips the breaker, cutting off the flow of electricity and protecting the circuit.

The IELBXK11-1REC5-70044-55-C circuit breaker also includes an instantaneous trip device that trips the breaker much more quickly than the overload trip element. This feature is advantageous in short circuit protection, as it detects an overload condition much faster and trips the breaker before an extensive amount of current can flow through the circuit, potentially causing damage to the system.

The IELBXK11-1REC5-70044-55-C circuit breaker also features a time-delay trip element, which is adjustable and designed to provide protection against nuisance tripping in light load and low-level faults. The integrated system of the IELBXK11-1REC5-70044-55-C also provides thermal protection by measuring the heat generated by the circuit breaker, and automatically trips the breaker if necessary to prevent overheating.

Conclusion

The IELBXK11-1REC5-70044-55-C circuit breaker is a robust and reliable circuit protection device that is suitable for many types of applications. Its reliable current-sensing element, instantaneous trip device, and time-delay trip element provide users with fast and reliable protection against electrical overloads or short circuits. In addition, its integrated thermal protection system helps prevent overheating, ensuring the long-term reliable operation of the circuit breaker.
