A 992120 circuit breaker is an electrical safety device designed to provide electrical protection from sudden excess of current or overloading. It’s automatic switching device and consists main contact, auxiliary contact and electromagnetic coil. Its life expectancy is more than 100,000 operation cycles. It is the most efficient way to protect your system, machines and components from damage due to overload, short circuit, surge and fault current.

Circuit breakers have various types. Some of the most common types include 1-pole, 2-pole and 3-polebreakers. The 1-pole breakers are used with small appliances and outlets, while the 2-pole breakers are used for larger devices. The 3-pole breakers are used for protecting 3-phase systems. The main advantage of the 3-pole breakers is that they offer more protection, as they detect ground faults more quickly and accurately. All three types of breakers are available in both 220-240 V AC and 480 V AC versions.

The 992120 circuit breaker works on the principle of thermal, electromagnetic and hydraulic. Thermal breakers are responsive to changes in temperature. They have thermal elements which expand and contract with the changes in temperature. When the temperature rises, the thermal elements expand and open the contacts, thus, interrupting the current. Similarly, when the temperature drops, the thermal elements contract and close the contacts, thus, allowing the current flow.

The electromagnetic and hydraulic breakers work on the principle of current or pressure. The electromagnetic breakers respond to changes in current, while the hydraulic breakers respond to changes in pressure. When the current exceeds the breaking capacity, the breaker will open and interrupt the current. Similarly, if the pressure exceeds the breaking capacity, the breaker will open and interrupt the current.

One of the most important applications of 992120 circuit brake is in the protection of equipment and systems from excessive current or overload. The breaker helps to automatically switch the device off when the current exceeds the rated value, thus, preventing any damage due to excessive current or overload. It can also be used in the control of short-circuit, surge and fault current. Additionally, it can be used to provide protection against overload of electrical wiring and systems.

The 992120 circuit breakers are easy to install and can be used in most electrical systems. They are also reliable and cost effective, offering a long service life. Additionally, they are available in different current ratings and designs, making them suitable for almost any application. It is therefore the ideal choice for protection against current overload, short circuits, surges and fault current.
