Circuit Breakers

A circuit breaker is a protective device designed to interrupt an electrical circuit in the event of an overload or short circuit. One of the most common circuit breakers in use today is the APG66-35053-1, a two-pole thermal magnetic circuit breaker. It is a reliable and cost-effective solution that provides high performance and long-term reliability.

The APG66-35053-1 circuit breaker is suitable for applications in a wide range of industrial, commercial, and residential environments. It can be used to protect transformers, motors, and other electrical equipment from fault currents. It is available in both single- and three-pole configurations, and it comes with a range of overload and short-circuit currents.

The APG66-35053-1 circuit breaker works on the principle of thermal magnetic operation. Its construction consists of a thermal element and a magnetic element. The thermal element is activated when the current exceeds the rated current, causing the bimetal contacts to open and interrupt the circuit. This prevents the current from rising any further and causing an overload or short circuit.

The magnetic element is used to sense the overcurrent. It is comprised of a coil surrounded by a permanent magnet. When the current exceeds the rated current, the coil generates a magnetic field which causes the magnet to attract a latch, opening the circuit. It then latches in the opened position to ensure the circuit remains open until the fault is cleared.

The APG66-35053-1 circuit breaker also features adjustable overcurrent settings. This eliminates the need for costly and time-consuming cutting and welding operations. The adjustable settings also enable the user to select the precise current trip level and time delay needed for their application.

Other features of the APG66-35053-1 include a manual override flap, tamperproof screws, and integrated status indicators. Together, these features provide efficiency while ensuring the safety of the system and personnel.

The APG66-35053-1 is a highly reliable, cost-effective, and easy to install solution for overcurrent and short-circuit protection. It provides a number of features that enable users to select the optimal current operating level and time delay settings for their specific applications. With its reliable performance and long-term reliability, it is an excellent choice for any industrial, commercial, or residential application.
