Circuit breakers are electrical systems that are designed to protect an electrical circuit from damage due to excess current, thermal overload, or short circuit. The 3DU15R is a type of circuit breaker that is used in applications such as industrial control circuit, motor control, protection of electrical equipment and circuits, commercial, residential, and institutional buildings.

The 3DU15R is a non-automatic, low voltage, general use circuit breaker that is designed to provide over-current protection for electrical circuits. It is usually used in distribution, control and protection circuits that have a current rating up to 15A.

The 3DU15R circuit breaker consists of a number of components that work together to provide protection from over-current conditions. These components include a trip lever, a fuse, a trip switch, and a trip detection coil.

The trip lever is a mechanical device that is used to manually open and close the 3DU15R circuit breaker. This lever can be operated by either hand, or in some cases by an electric motor in order to trip the breaker when an over-current situation is detected.

The fuse is located inside the 3DU15R circuit breaker and is designed to protect the circuit from excessive current. The fuse will provide protection by blowing, which will open the circuit and stop the flow of current.

The trip switch is located on the outside of the 3DU15R circuit breaker and operates by detecting an over-current situation. This switch will activate the trip lever in order to trip the breaker open when an over-current is detected.

The trip detection coil is located inside the 3DU15R circuit breaker and works by measuring the current flow in the circuit. If the current flow is higher than expected, the coil will activate the trip switch and trip the breaker.

The 3DU15R circuit breaker is designed to provide protection from over-current conditions by tripping the circuit breaker when an over-current is detected. This will prevent the circuit from being damaged by over-current and help to maintain the integrity of the system. The 3DU15R circuit breaker can also be used in residential and commercial applications where the current rating is 15A or less and the need for additional protection is required.
