Circuit breakers are crucial components that are used in all sorts of industrial, agricultural, and residential applications. They are responsible for protecting the electrical systems and equipment from shorts, overloading, and ground faults. The 3131-AF1NQ-000000-1Y3-20A circuit breaker is designed for medium-voltage applications. Understanding the application field and working principle of the 3131-AF1NQ-000000-1Y3-20A circuit breaker can help to ensure safe and efficient operation.

The 3131-AF1NQ-000000-1Y3-20A circuit breaker is designed for use in applications where the system voltage is 5kV or greater. These applications include medium-voltage overhead lines, electrical substations, and switchgear assemblies. Due to the high voltage of these applications, the circuit breaker must be able to handle high electrical loads and must also be able to trip quickly in the event of a fault.

The 3131-AF1NQ-000000-1Y3-20A circuit breaker is a two-pole circuit breaker that uses a thermal-magnetic trip unit. This type of trip unit uses two sensors: a thermal sensor and a magnetic sensor. The thermal sensor is designed to detect excess temperatures, which can be caused by an overload or a short. The magnetic sensor is designed to detect increases in current draw, which can be caused by a short or an overload. If either of these sensors detects an increase, the trip unit will open the circuit and electrically isolate the fault.

The 3131-AF1NQ-000000-1Y3-20A circuit breaker has a current range of 80-1600A. This means that it is suitable for applications where the current draw is no more than 1600A. The circuit breaker is also able to trip quickly when an overload or short occurs, which helps to protect the system and reduce the likelihood of an electrical fire.

The 3131-AF1NQ-000000-1Y3-20A circuit breaker is tested to meet all applicable standards, including UL and CSA, making it a safe and reliable device for medium-voltage applications. The circuit breaker is also RoHS and REACH compliant, meaning that it is free from hazardous substances and is safe for the environment.

In summary, the 3131-AF1NQ-000000-1Y3-20A circuit breaker is designed for medium-voltage applications with a voltage of 5kV or greater. The circuit breaker uses a thermal-magnetic trip unit to monitor the current draw and trip quickly in the event of an overload or a short. The circuit breaker is also tested to meet applicable standards, making it a safe and reliable device for use in medium-voltage applications.
