Fuses

The 0293030.MXJ is a time-lag fuse manufactured by Mersen, which offers high interrupting ratings and superior clearing capability for higher currents. It is suitable for both AC and DC applications and is designed to detect and protect against both overloads and short circuits. This makes it ideal for use in a variety of industrial, commercial and consumer electrical systems and applications.

Application Field

The 0293030.MXJ time-lag fuses are commonly used in large industrial systems, such as motor control circuits, heating and air conditioning systems, transformers, and capacitor banks. It is also suitable for use in residential and commercial units, such as air conditioners, refrigerators, stoves, ovens, dishwashers, light fixtures, and other appliances. In addition, the fuses are used in the automotive industry, as well as in both manual and automatic transfer switches and motor starters.

Working Principle

The 0293030.MXJ fuse works on the principle of “time-delay”. When the current level passes a certain threshold, the elements inside the fuse will heat up and eventually melt, which breaks the circuit. The time delay is important because it allows the fuse to respond to only excessive current levels, while allowing normal current to pass through without tripping the circuit breaker. This prevents nuisance trips.

The elements inside the 0293030.MXJ fuse are designed to safely respond to short-circuit and overload conditions without damaging the protected devices or source. This is accomplished through the use of an arc-suppressing device included in the design, which will absorb and dissipate the changes in current intensity during an overload or short circuit condition.

Additionally, the 0293030.MXJ fuse design has a high cycle rating, which means it can support many reset cycles in its lifetime. It also has a high current response speed, which enables it to quickly shut off power in the event of an abnormal current or overload situation. This time-delay fuse can handle 2-4 times the rated current of the load before tripping, which can help protect the electrical system from catastrophic damage.

Conclusion

The 0293030.MXJ fuse is a reliable and versatile piece of technology designed to protect electrical systems from damage caused by overloads and short circuits. It has a high interrupting rating, can handle loads up to 2-4 times the rated current, and has a cycle rating that ensures long-term operation. This time-delay fuse is suitable for both AC and DC applications.
