049402.5NR

049402.5NR Application Field and Working Principle

The 049402.5NR is a type of fuse which is mainly used to protect electrical devices from overcurrents. It is widely used for protection of remote control circuits, lighting circuits, alternative systems, renewable energy sources, and intelligent instrument controllers. It is a fast-acting fuse and designed with a built-in open frame type design for easy installation.

The 049402.5NR is a multi-pole fuse with a high breaking capacity that can effectively protect electrical equipment from any kind of current surges due to overloads. It also has a high current carrying capacity, making it suitable for applications that require maximum current carrying capacity. It is designed in such a way that it can be connected and disconnected in quick succession. It also has a wide range of current ratings, making it suitable for different types of applications that require different current ratings.

The 049402.5NR has two main features, low internal resistance and fast acting characteristics. The low internal resistance ensures that it can respond to any current surges in a quick and efficient manner, while the fast acting characteristics ensures that it operates at optimal performance to protect the circuit from any fault conditions. It is also designed with high temperature ratings, meaning that it can be used in applications with high temperatures.

Working Principle

The 049402.5NR fuse works by using a circuit breaker to disconnect the power supply when a current surge is detected. It uses a thermal element that can detect any increase in temperature due to a current surge. When a current surge is detected, the circuit breaker will open up and isolates the power supply from the protected circuit. The fuse will then cool down and reset itself once the current surge has been stopped. This allows the protected circuit to be safely reconnected and the power supply to be reinstated.

Advantages

The 049402.5NR fuse is an effective and economical way to protect against any overcurrents in any electrical system. It is a reliable and durable device that has been designed to withstand any conditions. Its quick-acting characteristics make it ideal for use in application where fast response is needed and its high current carrying capacity makes it suitable for heavy loads.

This fuse is also designed with an open frame design which allows for easy installation and maintenance. Additionally, the high temperature ratings make it suitable for use in applications with high temperatures. It is also an environmentally friendly device that uses minimal energy to operate. Overall, the 049402.5NR fuse is an excellent choice for use in applications that require fast response and high current carrying capacity.
