Circuit Breakers: IELHR111-26268-10-V Application Field and Working Principle

Circuit breakers are widely used in industrial and commercial application, as they are an essential method for controlling and protecting electrical circuits from potential damages caused from unexpectedly high current. The IELHR111-26268-10-V circuit breaker produced by Eaton Incorporated is one of the most popular such devices among professionals in the electrical industry today. This article provides an overview of the application field and working principle of the IELHR111-26268-10-V circuit breaker.

Application Field

The IELHR111-26268-10-V circuit breaker is made for use with 3-phase alternating current at 240 volts, with a rated current of 10 amps and a short-circuit interrupting capacity of up to 18kA at 480V. The breaker also provides a circuit trip current of up to 6.5 amps, and it is compatible with Eaton’s variety of industrial control and load measurement devices, including motor circuit protectors, surge protectors, and current/voltage meters.This makes the circuit breaker well-suited for industrial applications where high currents, frequent trips, and immediate response time are essential for the safety of the operation. Examples include machine tools, construction sites, manufacturing plants, and utility power systems.

Working Principle

The IELHR111-26268-10-V circuit breaker is a typical thermal-magnetic device, with both a thermal and a magnetic element competing for control of the circuit. The thermal element is a bimetallic disc, which is heated when current passes through it. The heat causes the disc to expand, bending an appropriate link to trip the breaker. But the magnetic element responds more quickly to current overload, but with lower sensitivity, allowing it to work together with the thermal element for an enhanced protection function. As such, the magnetic element helps shape the current and reduce any possible instability due to high fault currents, thus expanding the protective capability of the breaker. The magnetism is provided by a solenoid, which is energized by current and uses the Lorentz force to trip the breaker. The solenoid is connected to an operating lever, which, when energized, forces a mechanical switch into its open position, disconnecting the circuit.

Conclusion

The IELHR111-26268-10-V circuit breaker is a high-power, high-precision device designed to protect industrial and commercial installations from current overloads. The combination of a thermal and a magnetic element gives it fast response times and greater protection against current overloads. Its compatibility with Eaton’s wide range of devices makes it a versatile and reliable choice for any industrial or commercial setting.
