Fuses

Fuses are one of the most important components in electrical circuits, providing reliable and economical protection for low- and medium-voltage equipment and circuits. Fuses are a mechanical device designed to prevent inadvertent arcing between two pieces of conductor, thus protecting the components or devices connected downstream from excessive current, overloads and short circuits. One such device is the 0495040.ZXA, a three-phase thermal-magnetic low-voltage circuit breaker.

Application Field of 0495040.ZXA

The 0495040.ZXA is a low-voltage three-phase thermal-magnetic circuit breaker designed for use in various industrial, commercial, and residential applications. It is suitable for operating indoors and outdoors where the temperature ranges from -25°C to +50°C. The circuit breaker is rated up to 400A and has an overload current protection maximum of 500A. It also has a short-circuit protection maximum of 8kA at 500V.

The 0495040.ZXA can be used for residential and commercial low-voltage applications, such as flashers, wiring systems, electrical boxes, and other industrial applications. It is also suitable for use in motor control circuits, power generation and distribution systems, motor control centers, and other industrial-grade applications.

Working Principle of 0495040.ZXA

The 0495040.ZXA uses both thermal and magnetic overcurrent protection to protect against an overcurrent or short circuit in a circuit. In the event of an overcurrent, the thermal element will activate, tripping the breaker and isolating the circuit. This will help to protect against damage to appliances and other devices downstream. In addition to thermal protection, the 0495040.ZXA also benefits from a dual-decked magnetic element, which allows the breaker to react quickly to short circuits and overcurrents.

The 0495040.ZXA is also designed to be highly resistant to vibration, temperature, and other environmental factors, ensuring reliable protection for low-voltage applications. The breaker also has features such as a visible indicator to show when the breaker has tripped and a high temperature rating.

Summary

The 0495040.ZXA is a three-phase thermal-magnetic low-voltage circuit breaker designed for use in various industrial, commercial, and residential applications. It is highly resistant to vibration, temperature, and other environmental factors, and offers both thermal and magnetic protection. The 0495040.ZXA is suitable for operating indoors and outdoors where the temperature ranges from -25°C to +50°C, and is rated up to 400A with an overload current protection maximum of 500A and a short-circuit protection maximum of 8kA at 500V.
