A circuit breaker is an important device in electrical systems, whereby a circuit is disconnected from the power source for a specified period of time when it experiences an overload or a short circuit. 9129583500 is the designation of a specific type of circuit breaker and its application field and working principle are important factors in evaluating its effectiveness.

9129583500 is a high-pressure, molded-case, single-pole circuit breaker. It is designed to provide protection for circuits by automatically disconnecting them when current rises to an unsafe level. The breaker is equipped with built-in overcurrent and reverse current protection, as well as a manual switch for manually disconnecting the circuit. It is usually used in residential and commercial applications such as boilers, air conditioners, refrigerators, and other large appliances.

The working principle of 9129583500 is based on a thermal-magnetic circuit breaker. Inside the device is a thermal-magnetic heat element that reacts to excessive current, producing heat when current rises too high. As the heat increases it increases the area of the heat element and the magnetic field generated by the heat element increases, pushing the trip contacts together and thereby disconnecting the circuit. This break in the circuit will remain until the current is removed and the trip contacts can reopen.

The surge current handling capacity of 9129583500 is 3500A, which is adequate for most residential applications. It also has a short-circuit capacity of 7000A and an interrupting capacity of 12000A. This breaker is also designed to provide a breaking capacity of 2.3kA with a 400V pick-up current and 2.5kA with a 500V pick-up current. The operating temperature range is -25°C to 70°C, ensuring that the device functions correctly even in extreme temperatures.

9129583500 is designed with safety in mind and is UL rated and CSA certified. The construction is designed to minimize arc flash and is equipped with a built-in thermal trip and a shunt trip feature. The design also minimizes the risk of accidental contact with energized wires, and the breaker is built to be easily opened and reset if necessary.

The 9129583500 circuit breaker is an excellent choice for reliable and cost-effective circuit protection in residential and commercial applications. Its design allows it to provide protection against overloads and short circuits, as well as manual disconnection, with features such as a shunt trip and a built-in thermal trip to minimize the risk of arc flash. As such, it is an excellent choice for reliable circuit protection in any application.
