Circuit Breakers

A circuit breaker is an electrical device designed to protect an electrical circuit from damage caused by excess electrical current or overload. Circuit breakers can be manual, automatically operated, or remotely operated. A circuit breaker is an important part of any power system as it allows for the safe and efficient operation of the system by automatically disconnecting the circuit when it detects a fault.The W28-XQ4D-8 is a type of circuit breaker manufactured by the Schneider Electric Company. It is a 3 pole circuit breaker and is rated for up to 480 Volts AC. The W28-XQ4D-8 is suitable for use in the most demanding applications, such as those involving large motors and electrical distribution systems. It features adjustable trip settings for improved protection and is UL listed for safety.

Application Field

The W28-XQ4D-8 is designed for a wide range of applications, including industrial, commercial, and residential. It is suitable for use in various types of facilities, such as power plants, substations, distribution transformers, and residential buildings. The W28-XQ4D-8 is also suitable for use in harsh environments, such as marine or dusty environments, where it can provide maximum protection against overloads and short circuits.

Working Principle

The W28-XQ4D-8 circuit breaker works using two types of protection: thermal protection and magnetic protection. The thermal protection is provided by an internal bimetallic strip which is designed to heat up when an overcurrent passes through the breaker. This causes the strip to bend and the breaker to trip, disconnecting the circuit and preventing it from overloading. The magnetic protection is provided by a solenoid valve which trips when it detects a sudden change in the magnetic field caused by a short circuit. The breaker then disconnects the circuit, preventing further damage or even a fire.

In addition to the primary protective functions, the W28-XQ4D-8 also includes features such as a visual indicator to alert the user when the circuit has tripped, locking-out devices for operator safety, manual reset, and adjustable trip settings for better protection. The W28-XQ4D-8 is a reliable and safe circuit breaker, and is recommended for use in various applications.
