6720005322

Introduction

The 672005322 is a circuit breaker, which is suitable for high voltage systems, and most commonly used in the power industry. Circuit breakers are mainly used to protect electrical systems from short circuit and other overloads. 672005322 has become a common breaker used in the power system due to its reliable and robust performance. It is a variable-frequency drive (VFD) rated breaker also called a variable-frequency voltage-rating (VFVR) breaker.

Application Field

The 672005322 is suitable for alternating current arc fault, short circuit, overload, and double fault protection. It is available in two types: variable-frequency and conventional. The variable-frequency type is widely used for motor control, protection, and generation applications. It provides high-voltage electrical protection and performs operations that a conventional breaker cannot do. While the conventional type is mainly used for load shedding purpose.

The 672005322 has an adjustable trip current setting, allowing it to tailor to specific operating conditions, such as high altitudes, long-distance transmission, and operation with non-linear loads. Additionally, it can be used in motor control applications, providing motors with superior protection, such as inrush current limiting, under voltage protection, and overvoltage protection. It is also suitable for applications involving sensitive components, such as power electronics and electric traction systems.

Working Principle

The 672005322 operates using the principle of stored energy. When an overload or short circuit occurs, the 672005322 detects it and releases stored energy in the form of heat and mechanical force, which actuates the breaker’s contacts to open. The breaker then breaks the over current circuit, protecting the system from further damage.

The 672005322 can be energized with a voltage rating of up to 12000 Volts. When activated, it uses the stored energy to start an arcing process that quickly breaks the current. It also uses a patented trip mechanism to identify current faults, which allows it to react faster than traditional devices. Additionally, it features a self-test mode, which allows it to continuously monitor the integrity of the control system.

Conclusion

We have seen that the 672005322 is a circuit breaker commonly used in the power system. Its main applications are in motor control, protection, and generation applications, as well as for load shedding purpose. The 672005322 operates using the principle of stored energy, which is released in the form of heat and mechanical force when an overload or short circuit occurs, breaking the over current circuit.
