2JQ 250-R

Fuses have been used in many applications, including 2JQ 250-R, for a long time to provide overcurrent and overvoltage protection for both commercial and residential components. The 2JQ 250-R is a robust, easy-to-install, and cost-effective solution that provides reliable protection for a wide variety of electrical and electronic components.

Application Field

The 2JQ 250-R fuse is used mainly in medium-voltage applications such as industrial control equipment, power distribution systems, and electrical distribution systems. Electrical protection for low-voltage applications such as residential and commercial premises, as well as other sensitive components, can also be provided by this fuse. The 2JQ 250-R fuse has a rating of 2.55kVAC and a current rating of 10A. Other features include a 660VAC breaking capacity and a response time of ≤4 seconds. The fuse\'s dual-element design allows it to provide both current and voltage protection.

Working Principle

The 2JQ 250-R fuse operates by using a quenching action to protect against overcurrent and overvoltage events. The fuse contains two elements, a metal-oxide varistor (MOV) and a dual-element fuse. The MOV is designed to reduce the voltage when an overvoltage event occurs in order to protect the connected equipment, and it also serves to divert current away from the fuse element. The dual-element fuse element is designed to detect an overcurrent condition and quickly respond by melting the fuse link and breaking the circuit. The 2JQ 250-R fuse has a minimum breaking capacity of 660VAC.

The fuse element also has a self-resetting feature. In the event of an overcurrent event, the element will reset itself after the current is reduced, typically within 4 seconds. This allows the equipment to be restarted without having to replace the fuse. The 2JQ 250-R fuse also has a wide temperature range of -40 to +85 degrees Celsius, making it suitable for use in a variety of environmental conditions.

Conclusion

The 2JQ 250-R fuse is a robust and cost-effective solution that provides reliable protection for a wide variety of electrical and electronic components. It is simple to install, provides both current and voltage protection, and is suitable for use in a wide range of temperatures. The fuse\'s self-resetting feature allows it to automatically reset after an overcurrent event, meaning that equipment can be restarted without having to replace the fuse.
