Circuit breakers are safety devices used to protect facilities from overloading, overvoltage, and short-circuiting. The APG1-1REC2-2916-16 is a popular circuit breaker manufactured by ABB. Its application field and working principle are explained below.

Applications

The APG1-1REC2-2916-16 is used mainly in industrial and commercial installations. It is suitable for all types of AC applications up to 230V, with a rating of up to 30A. It is suitable for single-phase and three-phase applications, with a breaking capacity of 10000A Icu. This makes it ideal for motor and lighting circuits, as well as residential, commercial, and industrial applications.

Working Principle

The APG1-1REC2-2916-16 is designed with an electromagnetic trip unit. This trip unit is made up of a bimetallic strip, which is surrounded by a coil. When an overcurrent flows through the trip unit, the bimetallic strip heats up, and eventually reaches its breaking point. At that point, the trip unit disconnects the circuit, thus preventing any further damage or risk to the attached equipment.

The circuit breaker also features a thermal-magnetic operation. This means that, in addition to the bimetallic strip and heating coil, it also contains a thermal overload protection that triggers in the case of an overload. This protection is designed to activate if the overload current persists for an extended period of time. Once activated, it disconnects the circuit, ensuring that the equipment remains intact.

Advantages

The APG1-1REC2-2916-16 provides ample protection for circuits and equipment, as well as enhanced safety for personnel working with the equipment. It is easy to maintain and install, and features a self-sustaining design, meaning that it does not need additional auxiliary power supplies. The thermal-magnetic operation also ensures that the system is always protected, regardless of whether the overload is short or extended.

The circuit breaker also features a contact system that is designed to minimize arcing. This feature helps to improve safety for equipment and personnel, and also helps to prolong the lifespan of the unit, as it minimizes the wear and tear on its contacts.

Conclusion

The APG1-1REC2-2916-16 is an effective protection device for industrial and commercial installations. It is designed for maximum protection, featuring both electromagnetic and thermal-magnetic operation, as well as an arcing-minimizing contact system. This makes it an ideal choice for those who want enhanced safety of personnel and equipment, as well as increased lifespan of the system.
