105-P30-2A

Circuit breakers are devices used to protect electric equipment from damage resulting from an overload, short circuit, and/or ground fault. The 105-P30-2A circuit breaker is a general-purpose breaker that is commonly used in residential, commercial, and industrial applications. It is used in combination motor controllers, distribution panels, single-pole switching, and more.

The 105-P30-2A circuit breaker is an air-break circuit breaker which means that it uses an air gap between the contacts to provide an interruption in the electrical circuit. It is composed of three different parts: the operating mechanism, the contacts, and the enclosure. The operating mechanism is responsible for controlling the movement of the contacts, opening and closing the circuit breaker when needed. The contacts are the parts of the circuit breaker that actually carry the current and open or close to break the circuit. The enclosure is the housing that holds the operating mechanism and contacts, protecting them from the environment.

The rated breaking capacity of the 105-P30-2A breaker is 30 amperes, and it is UL listed, CSA certified, and suitable for grounding. It is also rated for up to 480 volts and has a maximum of 10 horsepower. The device is tripping class 10 and is thermal-magnetic in nature, meaning that it uses both the current flow and the temperature of the device to detect when it is necessary to open the circuit.

The working principle of the 105-P30-2A circuit breaker is pretty simple. When power is connected to the circuit, the operating mechanism senses the current and temperature. When the current reaches or exceeds the rated breaking capacity of the breaker, the operating mechanism will trigger and open the circuit, disallowing the excess current to cause damage to any devices or components in the circuit. After the current has been cut off, the breaker can be reset so that the circuit can be reopened again.

The 105-P30-2A circuit breaker is used in many different applications, including motor circuits, office equipment, lighting, and more. It provides overcurrent protection and is able to break frequently, making it ideal for applications that require frequent circuit breaking. The device is easy to install and use, allowing it to be used in both residential and commercial applications. Overall, the 105-P30-2A is a reliable and cost-effective breaker that can provide protection to a wide variety of circuits.
