Circuit Breakers are an essential part of any electrical system, protecting the various components from damage by stopping the flow of electricity in the event of an overload or short circuit. CB255-20 is a specific type of circuit breaker manufactured by Hammond Power Solutions for use in electrical switchgear applications. This type of breaker has been designed and tested to meet the requirements of a wide range of commercial and industrial applications, making it an ideal choice for those looking for an efficient and reliable safety device. In this article, we will discuss the application fields and working principles of CB255-20 circuit breakers.

CB255-20 circuit breakers are designed for use in low voltage AC electrical systems, both in circuits up to 600V and systems up to 2000A. This type of breaker is especially suitable for use in generator protection systems and rectifier systems, as well as any other kind of power switching application. The CB255-20 breaker features a trip unit that is designed to detect and respond to both overcurrent and undercurrent conditions. It also comes with a set of adjustable trip settings, allowing you to accurately set the settings according to your specific application requirements. The adjustable trip settings enable the breaker to respond quickly and precisely to any excursions in current, thus protecting your system from potentially damaging overloads or short circuits.

This breaker is equipped with a thermal-magnetic trip unit, which is the core of the breaker\'s working mechanism. The trip unit consists of two parallel-connected coils that sense the current in the system and actuate a plunger that trips the breaker when the appropriate current is exceeded. The thermal portion of the trip unit is made up of a bimetallic strip that deforms when too much heat is generated, increasing the plunger\'s speed and tripping the breaker. The magnetic portion detects any increase or decrease of current and causes the plunger to quickly close or open, respectively.

The CB255-20 circuit breaker also comes with an auto reclosing feature, allowing it to automatically reset itself after an overload or short circuit has been detected. The auto reclosing feature is designed to make the breaker more reliable and reliable by preventing electrical system errors from occurring again. This is achieved by momentarily interrupting power to the system and then allowing it to return to normal operation after a certain period of time.

CB255-20 circuit breakers are UL listed and certified, making them suitable for use in a wide variety of applications. They are also UL classified for type SP: Low Voltage Circuit Breakers, making them ideal for high voltage applications, such as generator protection systems. In addition, these breakers are compliant with the IEC/EN 60947-2, making them suitable for use in industrial applications.

CB255-20 circuit breakers provide reliable and efficient protection from overloads and short circuits. In addition, their adjustable trip settings enable them to respond quickly and precisely to any fluctuations in voltage, making them an ideal choice for those seeking an efficient and reliable safety device. With their UL listing and IEC/EN 60947-2 certification, these circuit breakers are suitable for use in a wide range of commercial and industrial applications, making them a great choice for both small and large businesses.
