Introduction to 203-15-20087-2 Circuit Breakers

Circuit breakers are an essential component of electrical systems, providing protection against dangerous overloads and short-circuits. The 203-15-20087-2 is a dual-function circuit breaker designed to protect both single- and three-phase systems. This type of circuit breaker offers superior protection against overloads and short circuits. It is suitable for a variety of applications, from commercial and residential buildings to industrial and marine environments.

Operation and Protection

The 203-15-20087-2 circuit breaker works automatically and does not require manual operation. It is rated for currents from 15A to 200A, with an adjustable trip range from 6A to 90A. When an overload or short-circuit occurs, the breaker\'s bimetallic strip rapidly expands, pushing the breaker arm into the off position. This effectively disconnects the power source, protecting the circuit and preventing further damage.

Thermal and Magnetic Circuit Breakers

The 203-15-20087-2 breaker utilizes both thermal and magnetic protection. Thermal protection relies on the physical movement of insulation-wrapped bimetallic strips to trip the breaker in the event of an overload. This type of protection is suitable for most light-duty applications. Magnetic protection, on the other hand, utilizes a current sensing coil to detect faults in the circuit and trip the breaker accordingly. This type of protection is suitable for more complex and high-intensity applications.

Main Features

The 203-15-20087-2 circuit breaker has a variety of features that make it suitable for all types of applications. It is equipped with self-test and reset capabilities, allowing it to automatically detect and protect against overloads and short-circuits. It is also UL Certified, making it one of the few circuit breaker models approved for use in the US and other parts of the world. Moreover, the 203-15-20087-2 has an exceptionally low failure rate, making it one of the most reliable types of breakers available.

Applications

The 203-15-20087-2 is suitable for a variety of applications, from residential and commercial buildings to industrial and marine environments. It is often found in HVAC systems, computer rooms, lighting systems, and motor-control systems. In addition, the breaker is suitable for use in trailers, buses, and boats. Its thermal-magnetic dual protection makes it suitable for complex and high-intensity applications where extra protection may be needed. Furthermore, it is suitable for both indoor and outdoor use.

Conclusion

The 203-15-20087-2 is a dual-function circuit breaker designed to protect both single- and three-phase systems. Its thermal-magnetic protection and UL Certification make it suitable for a variety of applications, from residential and commercial buildings to industrial and marine environments. Its adjustable trip range from 6A to 90A, self-testing and reset capabilities, and low failure rate make it one of the most reliable circuit breakers available.
