B21-51-15.0A-02-00 circuit breaker is a general-purpose circuit breaker. It is designed for residential and commercial applications, offering protection from short circuits, overloads, and ground fault protection. Its principle of operation is simple; it is designed to open or close an electrical circuit when a fault or overload occurs. In order to accomplish this, the breaker is designed with two sets of electrical contacts – one set of contacts (called an arcing contact) is designed to detect a fault or overload, and the other set of contacts (called the main contact) is designed to either open or close the circuit.

When a fault or overload condition arises, the breaker’s sensing mechanism detects the anomaly and causes the arcing contact to move away from the main contact momentarily. This action causes an arc of electricity to form between the arcing contact and the main contact, which trips the breaker and breaks the circuit. This interruption of current flow in the circuit prevents any further damage or fire from occurring.

The B21-51-15.0A-02-00 circuit breaker offers several advantages over traditional circuit breakers. It has a high current rating of 15.0A and a short trip time of less than 1 second. It also features tamper-resistant features that prevent tampering with its settings by unauthorized personnel. This breaker is designed with a manual test button and is UL 489 approved. This approval indicates that it has passed stringent testing to meet industry safety standards.

Circuit breakers are commonly found in residential, commercial, and industrial applications. In a residential setting, B21-51-15.0A-02-00 circuit breaker is ideal for providing overload protection to circuits that serve appliances and other electrical equipment. In commercial settings, the breaker is often used to protect equipment such as photocopy machines, vending machines, and motors.

B21-51-15.0A-02-00 circuit breakers are also commonly found in industrial settings, primarily in applications where large amounts of current are handled, such as welders and cranes, as well as in industrial process applications. In all these applications, the breaker’s arc-fault protection is an essential safety feature. The breaker’s fast-trip function helps prevent serious electrical damage and can even help save lives.

The B21-51-15.0A-02-00 circuit breaker is designed for reliability and convenience. It is UL listed, and its manual test button offers an easy way to test the breaker for proper operation. It also features tamper-resistant features that help prevent unauthorized personnel from tampering with its settings. The breaker is also designed to be maintenance-free, requiring no adjustment or calibration over its service life.

In summary, the B21-51-15.0A-02-00 circuit breaker is a reliable, convenient, and safe device that is suitable for both residential and commercial applications. It offers protection from short circuits, overloads, and ground fault protection, with a fast trip time and tamper-resistant features. The breaker also comes with a UL listing and manual test product, making it one of the best circuit protectors on the market.
