1140-G251-P7M1-8A

1140-G251-P7M1-8A is a type of miniature circuit breaker made by ABB. It is classified as a “Circuit Breakers” product, a device used to protect an electrical circuit from excessive current. This product type is ideal for applications where space is limited.

The 1140-G251-P7M1-8A provides a wide range of protection and power switching requirements. With its manual reset and adjustable trip settings, it provides overcurrent protection and short circuit protection. It can handle up to 40A, making it suitable for a variety of residential, commercial and industrial applications.

The working principle of the 1140-G251-P7M1-8A is based on the principle of current limiting. When the circuit breaker is initially connected, the current flows freely. If the current reaches a current limit (also called a trip limit), the circuit breaker will trip and open the circuit, thus preventing the flow of excess current. This provides the necessary protection for the electrical circuit.

In addition to the current limiting protection, the 1140-G251-P7M1-8A also provides overcurrent and short circuit protection. Overcurrent protection ensures that the current in the electrical circuit does not exceed the rated current of the appliance. Short circuit protection prevents the current from exceeding the rating of the protective device, thus safeguarding against damage from a short circuit.

The 1140-G251-P7M1-8A is an ideal solution for residential applications, such as circuit breakers in panel boards, and for commercial and industrial applications such as circuit breakers for lighting, fans, pumps and motors. It is suitable for various kinds of electric equipment, including motors, power tools and household appliances.

The 1140-G251-P7M1-8A provides the necessary protection needed to keep electrical circuits safe and reliable. It is a reliable and cost-effective solution for a variety of applications and is designed to offer superior protection in a space-saving package.
