IUGNF66-35177-25 Circuit Protection

Circuit breakers are an important electrical safety device that protects all electronic equipment, their components, and people from potential harm. The IUGNF66-35177-25 is a relatively high voltage circuit breaker that is commonly used to protect industrial motors and power equipment. This article will discuss the application field and working principle of this circuit breaker.

Application Field

The IUGNF66-35177-25 circuit breaker is suitable for use in industrial motor and power equipment applications with an AC voltage of up to 220V and a maximum rated current of 315A. It can be used as a motor circuit protection device and also for protection of overhead lines, low voltage switchgear, and power distribution systems. It can also be used to protect transformers, alternators, and other large power equipment.

The circuit breaker features adjustable overload protection settings with a monitoring system that allows the operator to quickly detect any faults. This provides a greater level of safety and reliability for the user. It is also designed to withstand wide voltage peaks, meaning it is suitable for use in environments with power fluctuations. The IUGNF66-35177-25 is UL approved and certified, meaning it meets all required safety standards.

Working Principle

The IUGNF66-35177-25 uses an internally mounted shunt trip coil that is triggered by an external current. When the current exceeds the predetermined trip value, the coil is activated and the electrical circuit is opened. The circuit breaker has a feature called electromagnetic interference (EMI) protection, which helps to protect the surrounding electronic equipment from electromagnetic fields. This helps to ensure the safety of personnel and equipment in the vicinity of the circuit breaker.

The IUGNF66-35177-25 features an arc chamber that is designed to contain any arcs that are created when the breaker is tripped. This helps to protect the surrounding area from any sparks that may be created when the breaker trips. The circuit breaker also features a fast response time (up to 30 milliseconds) and can be manually reset if needed.

The IUGNF66-35177-25 circuit breaker is built to the highest quality standards, making it an ideal choice for industrial motor and power equipment applications. It provides reliable overload protection for motors and other equipment, as well as EMI protection for electronic components in the vicinity. The circuit breaker also features adjustable settings, fast response time, and an arc chamber for additional protection. It is UL approved and certified, making it a safe and reliable choice for industrial applications.
