UPG1-22489-5 Circuit Protection

A circuit breaker is a device in an electrical system or structure intended to protect it from excessive current. All circuit breakers are divided into two categories: low-voltage circuit breakers, which are used to protect the components in a low-voltage system, and high-voltage circuit breakers, which are used to protect the components in a high-voltage system. The UPG1-22489-5 model is a low-voltage circuit breaker.

The UPG1-22489-5 Circuit breaker is a Air type AC circuit breaker designed for minimum interrupting and current-limiting capacity in industrial and commercial low-voltage applications. It provides reliable protection against short-circuits, overloads, and ground-fault events. The circuit breaker features an intuitive design with easy adjustment of overcurrent protection levels and the ability to switch from manual to automatic operation. Additionally, the circuit breaker feature a wide range of operating parameters, allowing it to be used in any system requiring low-voltage circuit protection.

The principle of operation of the UPG1-22489-5 circuit breaker is based on a thermal-magnetic trip unit. The unit measures the current flow through the circuit, and if the current exceeds a predetermined level, the thermal element inside the unit reacts. This thermally-driven element causes a bimetal spring to release an arm, which then trips the circuit breaker, cutting off power to the circuit. This type of circuit breaker is designed to protect devices and sensitive equipment from overloads and short-circuits.

The UPG1-22489-5 circuit breaker is suitable for use in a variety of applications, from industrial and commercial to residential buildings. It is suitable for applications such as heating, air conditioning, lighting, motors and electrical appliances. Additionally, it can be used to help protect high-value equipment from lightning surges. The circuit breaker is suitable for use in wide range of operating voltages and is UL-approved for safety.

The UPG1-22489-5 circuit breaker is designed with safety and convenience in mind. The trip unit and its components are designed for reliable protection from the dangers of excessive electrical current. Additionally, the easy-to-use design allows for easy adjustments of current-limiting settings and rapid access to reset the circuit breaker. The robust design, UL-approval rating and variety of application make the UPG1-22489-5 circuit breaker an excellent choice for all low-voltage protection applications.
