Circuit Breakers

A 3120-F311-P7T1-W14DR4-5A circuit breaker is an electric switch designed to protect electrical systems, equipment, and networks from damage due to overloads, short-circuits, and other electrical problems. Its primary function is to detect excessive current and cut the power before electrical components on the circuit suffer damage or failure. Circuit breakers are typically found in residential, commercial and industrial settings.

The 3120-F311-P7T1-W14DR4-5A circuit breaker has a number of features that make it especially suited for its purpose. The 3120-F311-P7T1-W14DR4-5A circuit breaker is designed to switch off when current passes a specified threshold, typically due to a short-circuit or an overload, thus protecting electric components from damage. It can switch back on when the problem or excess current is eliminated, allowing the circuit to reset.

Application Field

The 3120-F311-P7T1-W14DR4-5A circuit breaker is widely used in all types of electric installations. It is suitable for AC/DC voltage and residual current detectors. Electrical panels in homes and businesses often contain circuit breakers, as these panels form the backbone of the electrical system.

The 3120-F311-P7T1-W14DR4-5A circuit breaker can also be used in electrical equipment such as electric tools, motors, and other large electric equipment to provide overcurrent and overload protection. In such applications, the circuit breaker can prevent equipment from damage due to short circuits and overloads.

On offshore platforms and other hazardous environments, the 3120-F311-P7T1-W14DR4-5A circuit breaker is often used as an emergency power cutoff switch to protect personnel from electric shock or fires caused by overloading. In these settings, the breaker can cut off power to electrical systems whenever an overload or short-circuit is detected.

Working Principle

At the heart of a 3120-F311-P7T1-W14DR4-5A circuit breaker is a sensing device that can detect current variation. When the current exceeds the specified limit, the breaker will react by tripping the circuit. This stops current from flowing and prevents further damage.

The 3120-F311-P7T1-W14DR4-5A circuit breaker also features a special switch known as the "trip coil." This coil engages the tripping mechanism when a current overload is detected. The current then flows through the trip coil, and the resulting force causes the contacts of the breaker to separate, cutting off the current.

The 3120-F311-P7T1-W14DR4-5A circuit breaker also incorporates other protection functions such as short-circuit protection. A short-circuit occurs when a high current passes through a short in the circuit, which can cause equipment damage and fires. With the 3120-F311-P7T1-W14DR4-5A circuit breaker, the inrush current is limited by a series of resistors and the contacts are opened if the current exceeds a specified level.

The 3120-F311-P7T1-W14DR4-5A circuit breaker also features overload protection, which helps to protect electrical systems and equipment from damage due to excess current. In such cases, the trip coil opens the contacts when a specified amount of current is exceeded, preventing further damage.

The 3120-F31-P7T1-W14DR4-5A circuit breaker is a versatile and effective tool for protecting electrical systems and equipment from damage due to overvoltage, short-circuits, and overloads. It is designed to quickly detect excessive current and switch off the power, thus preventing equipment from further damage or failure.
