Circuit breakers are widely implemented in many industrial, residential, and commercial settings. They are designed to protect electrical wiring from potential fault currents. The 209-3-25521-7 circuit breaker is a single-phase breaker designed for medium-voltage electrical applications. It is UL-listed and has an interrupting capacity up to 200kA (1 sec).

The 209-3-25521-7 breaker comprises a core element that is housed in a molded outer case. The core element is composed of a non-conductive plastic ring, an arc resistant plate, and two contact points. The core element receives the direct current from the main power source, and then transfers it to the connected equipment. The arc resistant plate protects the contact points from arcing when the circuit breaker opens and closes. The outer case houses the core element and provides protection against environmental hazards like corrosion and moisture.

The 209-3-25521-7 circuit breaker has several application fields. It is most commonly used in industrial applications such as industrial switchgear, motor control, and generators. It can be used in commercial and residential settings as well, where its main purpose is to protect the electrical wiring from overload and short circuit.

The 209-3-25521-7 circuit breaker works on a simple principle. When the electric current reaches its maximum limit, the contact points will open and the flow of current will be interrupted. This interruption prevents further damage to the equipment and stops the overload or short circuit from occurring. The contact points can then be closed once again and the flow of current will resume.

The 209-3-25521-7 circuit breaker is an important tool for protecting electrical wiring from damage and accidents. It is designed to be highly reliable and durable, with its arc resistant plate and UL-approved design. Overall, it is a great choice for single-phase medium-voltage applications that need reliable power protection.
