Circuit breakers are important electrical appliances used to protect circuits and equipment from overloads. They protect against serious electrical damage or fire that can result from an overload or short circuit. CB251-25 is a type of circuit breaker designed for residential and light commercial applications.

The CB251-25 is a single pole, 10A thermal magnetic breaker that is rated for 120/240VAC. It has the ability to handle any working voltage between 40A and 64A. It is suitable for use in single-phase or three-phase distribution panels, as well as light commercial applications.

The CB251-25 is designed to open or close a circuit when the current passing through it reaches the specified maximum current limit. The breaker operates using a thermal-magnetic mechanism, which is a combination of an instantaneous-acting thermal element and a time-delayed magnetic element.

The thermal element is a bimetallic strip that is located inside the breaker case. This element is able to sense temperature changes in the internal temperature of the circuit. When the thermal element senses a temperature increase, it triggers the breaker to trip.

The magnetic element is a solenoid that is located inside the breaker case. This element is able to sense changes in the magnetic field of the circuit. When the magnetic element senses a change in the magnetic field, it triggers the breaker to trip.

The CB251-25 has two operating modes, a manual mode and an automatic mode. In the manual mode, the breaker can be reset manually by pressing the reset button. In the automatic mode, the breaker will reset itself automatically after the overload or short circuit has been cleared.

The CB251-25 is designed to provide protection against overloads, short circuits, and ground faults. It is UL-listed, meaning it has been tested and approved for use in residential and light commercial applications.

The CB251-25 can be used as a main circuit breaker in residential and light commercial applications. It can also be used as a subpanel circuit breaker in larger commercial applications. It is a popular choice for homes, businesses, and commercial establishments because of its reliability, safety, and cost-effectiveness.
