IELH12-70437-1-V Application Field and Working Principle

The IELH12-70437-1-V is part of a family of circuit breakers that are used for various applications. Circuit breakers are one of the most important and versatile electrical safety components in any circuit, designed to protect against overcurrent, short circuit, and overvoltage. The IELH12-70437-1-V is commonly used in medium voltage systems and is designed to interrupt large amounts of current quickly. The applications of circuit breakers are varied, and they can be used in residential, commercial, and industrial systems.

Types of Circuit Breakers

Circuit breakers come in two main types: thermal and magnetic. Thermal circuit breakers use current to heat a bi-metallic strip, which then expands and causes the circuit breaker to trip. Magnetic circuit breakers use a coil of wire to create a magnetic field when current passes through it. This magnetic field trips the contacts inside the breaker to disconnect the power supply. The IELH12-70437-1-V is a magnetic circuit breaker, which is more sensitive and durable than its thermal counterpart.

IELH12-70437-1-V Specifications And Functionality

The IELH12-70437-1-V is a 3.6 kV, 65KA rated circuit breaker, designed for use in medium voltage systems. It is a three-phase device, and it can be wired in wye or delta configuration. The trip unit is programmed with adjustable time-current curves to ensure that the breaker will only trip when current reaches dangerous levels. The IELH12-70437-1-V also features a fault indicator light which can indicate the fault condition in the system. The internal components of the IELH12-70437-1-V are made of UL-listed materials, which provide superior performance and reliability.

IELH12-70437-1-V Working Principle

The IELH12-70437-1-V is designed to provide electrical protection against overcurrent, short circuit, and overvoltage. When the current load exceeds the rated value, the current passes through the coil and creates a powerful magnetic field. This magnetic field trips the contact inside the breaker, which then causes the breaker to open. If the current load exceeds the circuit breaker’s interrupting rating, the breaker will trip and isolate the power. The IELH12-70437-1-V is designed to open quickly, ensuring that it does not create a hazardous condition.

Conclusion

The IELH12-70437-1-V is a 3.6 kV, 65KA rated circuit breaker that is designed for medium voltage applications. It is a magnetic circuit breaker, which is more sensitive and durable than its thermal counterpart. The IELH12-70437-1-V is designed to protect against overcurrent, short circuit, and overvoltage in electrical systems. When the current load exceeds the rated value, the current passes through the coil and creates a powerful magnetic field, which trips the contact inside the breaker and isolates the power supply. The IELH12-70437-1-V is a reliable and efficient circuit breaker and can provide superior protection in any electrical system.
