IELHK112-30097-1 Application Field and Working Principle

Introduction

Circuit breakers are critical components of an electrical system; their function is to interrupt current in the event of a fault or overload. The IELHK112-30097-1 circuit breaker is a single-pole, thermal-magnetic breaker designed for use in three-phase applications, up to 440V AC. This breaker features a compact, lightweight design that saves space and reduces installation costs.

Application Field

The IELHK112-30097-1 circuit breaker is suitable for both industrial and commercial installations. It is ideal for low-voltage applications such as HVAC, solar power, and industrial equipment. The thermal-magnetic breaker provides instantaneous trip protection and reliable operation at temperatures as low as -10°C to +50°C. The circuit breaker is designed for use in residential, commercial, and institutional installations. It is also suitable for construction sites and other current-limited conditions. The breaker is compatible with a wide variety of accessories, including fuse holders, indicators, and lockout devices, making it an ideal choice for any electrical installation. It is UL 489 Listed and CSA certified for use in the United States and Canada.

Working Principle

The working principle of the IELHK11-30097-1 circuit breaker is based on the thermal-magnetic mechanism. This mechanism is a combination of both a thermal element and a magnetic element. The thermal element is responsible for sensing overloads and tripping the breaker in the event of an overload. The magnetic element is responsible for sensing short-circuits and also tripping the breaker in the event of a short-circuit.When the breaker is exposed to an overload current, the thermal element will heat up, eventually reaching its pre-determined trip point. Simultaneously, the magnetic element also senses the current and will begin to attract the trip latch, eventually tripping the breaker and removing power. In the event of a short-circuit, the magnetic element will immediately create a magnetic field that repels the trip latch and causes the breaker to immediately trip.

Conclusion

The IELHK112-30097-1 circuit breaker is a single-pole, thermal-magnetic breaker designed for three-phase applications up to 440V AC. This circuit breaker is suitable for a wide range of applications, including HVAC, solar power, and industrial installations. It features a robust design and a thermal-magnetic mechanism that provides instantaneous trip protection and reliable operation.
