Circuit Breakers — IALK1-39382-5 Application Field and Working Principle

Circuit breakers are important electrical devices that protect buildings, machines, and equipment from dangerous electrical faults and surges. The IALK1-39382-5 is a type of circuit breaker that is ideally suited for protecting circuits against overload and short-circuiting. It is commonly used in industrial machinery, buildings, and other high-current electrical systems.

The Anatomy of a Circuit Breaker

A circuit breaker consists of three main components; the trip unit, the case, and the contact system. The trip unit is a mechanical device that contains a circuit breaker mechanism, which is designed to detect overcurrent and short circuit problems. When excessive current flows through the circuit, the trip unit senses this and trips the circuit breaker to open the circuit and eliminate the danger. The case is the housing that conceals the internal components and gives the breaker some mechanical protection. The contact system controls current flow through the circuit and contains the main contacts, which can open and close the circuit.

IALK1-39382-5 Application Field

The IALK1-39382-5 is a three-pole, Type-1 circuit breaker with a rated current of 1000A and a rated voltage of 600V AC. It can be used in commercial and industrial applications, such as industrial machines, buildings, and high-current electrical systems. It is also suitable for marine, oil and gas, and solar energy systems, as well as for motor control centers.

IALK1-39382-5 Working Principle

The IALK1-39382-5 uses electromagnetic and thermal principles to detect and trip during an overload or short-circuit condition. The electromagnet trips when current exceeds the rated value, which causes the contacts to open, disconnecting the circuit. The thermal principle relies on an overcurrent-sensitive element that is heated when current exceeds a predetermined level, causing it to expand and trip the breaker. Aside from providing overload and short-circuit protection, the IALK1-39382-5 also incorporates several other features and functions, such as a lockable manual trip lever, motor operational control and protection, short-circuit trip indicator, and a momentary power failure indicator.

Conclusion

The IALK1-39382-5 is a high performance three-pole, Type-1 circuit breaker designed for commercial and industrial applications, such as industrial machinery, buildings, and high-current electrical systems. It uses both the electromagnetic and the thermal principle to detect and trip during overload and short-circuit conditions and offers additional features, such as a lockable manual trip lever, motor operational control and protection, and a momentary power failure indicator.
