Circuit Breakers

9926251004 application field and working principle

A circuit breaker is an automatically operated electrical switch designed to protect an electrical circuit from damage caused by overload or short circuit. Its basic function is to detect a fault condition and, by interrupting continuous current flow, to immediately discontinue electrical service to minimize damage to an electrical circuit. Circuit breakers are made in varying sizes, from small devices that protect an individual household appliance up to large switchgear designed to protect high voltage circuits feeding an entire city. The 9926251004 is a renowned device currently used for power systems in industrial and commercial applications.

The 9926251004 is a miniaturized circuit breaker with a nominal voltage rating of 600V, suitable for applications in Class A through G areas, as defined by the National Electric Code. It can be used in any three-phase system, with the availability of ratings up to 25A. As a UL 489 compliant device, it is ideal for use in motor-starting applications. It has a life expectancy of more than 140,000 operations at rated load, allowing it to handle a wide range of applications in industrial, commercial and residential systems.

The 9926251004 circuit breaker is a trip-free device with an interrupting rating of 10 kA at 600V. Making good use of its trip-free feature, it opens automatically when a short-circuit or overload occurs in a circuit,thus preventing damage or destruction of equipment or a fire hazard to buildings. In addition to its over-load protection, it is also equipped with a manual reset that trips if opened by a short-circuit or overload.

In addition to being used as a circuit breaker, the 9926251004 has a unique and additional feature that makes it suitable for use in motor control applications. This feature allows the circuit breaker to be used as a motor starter, providing a safe starting current to the motor and allowing the motor to run safely under normal conditions. By using this feature to control motor starting and stopping, the motor can more reliably start, stop and adjust its speed without worrying about over-current and power surges.

The working principle of the 9926251004 circuit breaker is simple. When an overload or short circuit occurs and exceeds the breaker\'s rated current, the built-in thermal element will heat up and expand, thus switching into its “trip” position and disconnecting the power supply to the circuit. If the overload or short circuit is small enough, the breaker may only trip partially, allowing some power to remain in the circuit. In cases where the overload or short circuit is more severe, the breaker will trip completely and the power is removed from the circuit.

The 9926251004 circuit breaker is an indispensable tool in the electrical industry. With its superior performance and reliable protection, it is perfect for protecting industrial, commercial and residential systems from damages caused by short circuit or overload. Its ability to provide safe motor control makes it a valuable tool for motor control applications. With features like trip-free reset, manual reset and overload protection, this particular circuit breaker is an outstanding choice whenever protection and safety of electrical systems is an issue.
