Circuit breakers are ubiquitous components of electrical systems. They are used to protect power circuits from overload and short-circuit conditions that can damage equipment and property. The SU3D2UC is a type of circuit breaker that is designed to detect and interrupt fault currents of up to 4.95 kiloamperes.

The SU3D2UC is a miniature circuit breaker that has a base rating of 3 amps. It has a general purpose design and is suitable for use in a wide range of applications, including residential, commercial, and industrial applications. Its compact size makes it useful in applications where traditional circuit breakers would be too bulky or expensive.

The SU3D2UC employs a tripping mechanism that is activated when the trip level is exceeded. The trip level is adjustable from 1.2 to 4.95 kiloamperes. When the trip level is exceeded, a spring-operated plunger retracts, which causes the trip lever to pivot and cause the contacts of the breaker to open. The contacts then remain open until the reset button is pressed, restoring the breaker to its normal state.

The SU3D2UC also incorporates a thermal cut-off mechanism. This mechanism is designed to trip the breaker if the temperature of the contacts rises to a critical threshold. The thermal cutoff mechanism helps to prevent overheating of the contacts during an overload or short circuit.

The SU3D2UC is designed to meet UL 1077 standards, which is the standard for miniature circuit breakers in the United States. It is RoHS compliant, meaning that it contains no hazardous materials such as lead or mercury. It is approved for use in a variety of applications, including residential wiring, commercial wiring, and machine control.

The SU3D2UC is a versatile and reliable circuit breaker that is designed to provide reliable protection against overload and short-circuit conditions. Its adjustment feature allows for a wide range of overcurrent protection, and its thermal cutoff mechanism ensures that the breaker does not overheat when activated. The SU3D2UC is a reliable, cost-effective solution for a variety of applications.
