Circuit breakers are devices that are used to protect a circuit from overloading or short circuiting. The 991230 is an example of a circuit breaker and is designed to provide protection against over-current and short-circuit conditions.The device consists of a pair of double-pole, serially connected contact blocks which are capable of interlocking with each other. The contact blocks are surrounded by a molded case, filled with dielectric fluid. This fluid functions as an insulator, preventing electrical currents from escaping the device and thereby giving it the separation from other electrical equipment.When an over-current or short-circuit condition occurs, the 991230 will trip to protect the circuit. The operation of this device is as follows. When the current passing through the contact blocks is greater than the rated current setting, the blocks will move apart. This causes the dielectric fluid to flow out of the casing and increased pressure to be created. This pressure pushes the contact blocks back together, thus interrupting the flow of current.When the current returns to normal, the contact blocks will again move apart and the dielectric fluid returns to its original state, allowing the current to flow again. The device is designed to reset itself automatically after a period of time, allowing the circuit to continue its usable life. The 991230 is capable of being externally reset should it be necessary.The 991230 is ideal for use in a wide range of applications where over-current and short-circuit protection are necessary. This includes domestic, commercial and industrial electrical systems, as well as other applications such as telecommunication systems, medical and military equipment.In addition, the 991230 is designed to be extremely easy to install and use. It is a cost-effective solution for protecting circuits, while also providing a reliable and durable performance. Furthermore, the device requires minimal maintenance and inspection, and its filters and contacts are self-cleaning, ensuring a long-lasting life.Overall, the 991230 circuit breaker is an ideal solution for providing current and voltage protection in a wide range of domestic, commercial and industrial applications. Its self-cleaning filters and sturdy contact blocks provide a reliable and durable performance, and its ease of use and low maintenance requirements make it a cost-effective solution for circuit protection.
