Fuses

Fuses are a type of circuit breaker device, designed to prevent overloading and short circuit of electrical circuits. Fuses can be used for both large and small electrical systems and are widely used to protect consumer electronics, industrial wiring, and electrical systems.

7CLS70-44R is a fast-acting, low current fuse offering protection to equipment and machines fitted with motors, motor controllers and drives. It prevents damage from overload and short circuits providing increased safety in hazardous systems.

Application Field

7CLS70-44R fuses are designed for use in industrial control applications such as motor drives, motor control systems, power supplies, electrical switchgears, controllers, and other related electrical and electronic equipment. The fuse offers an even faster response compared to most traditional fuses, making it perfect for applications where an instant shutdown is required. A few examples include machines used in aircraft engines, automotive, food and beverage, pharmaceutical, and industrial automation.

Working Principle

7CLS70-44R fuses operate on the principle of heat dissipation. The fuse element is composed of highly engineered Pyrex glass using a combination of metals that heat up and dissipate the excess current when the current exceeds the rating. The fuse element responds quickly to rapid current increases and short circuits. Once the metal melts, the arc formed breaks the circuit and stops the flow of current.

When this fuse is used in overload conditions, its heat dissipation capabilities ensure that only excess current is diverted. The temperature irregularities are then safely contained within the fuse body, ensuring the current stays within the rating. This prevents overload and short circuit damage from occurring in the circuit.

7CLS70-44R fuse eliminates the risks of technical failures due to current overload or short circuits in the circuit. It is a reliable and cost-effective solution for a wide range of industrial applications.
