Fuses are indispensable devices in electrical engineering, and 03261.25MXP fuses are widely used for the protection of electrical equipment. These fuses are also commonly referred to as "open fuse box." They are designed to break down and become non-conducting when an excessive current passes through, thereby preventing fires or explosions caused by overloaded circuits.

Application Field

03261.25MXP fuses are designed for use in many applications, especially those involving automotive, computer, and communication devices. They can be used in oil-filled transformers, transmission and distribution systems, and power plant equipment. They are also used in the protection of motor-driven units such as elevators and turbine-generators. This type of fuse has a high melting capacity, which allows it to safely handle large surges of electrical current.

The 03261.25MXP fuse is also designed for high load ratings and has a 20-amp to 250-amp capacity rating. This fuse provides reliable current interruption for both AC and DC systems. Furthermore, its high voltage rating ensures safe operation of current-sensitive components.

Working Principle

03261.25MXP fuses are designed to operate on the basis of their melting action. When an overcurrent passes through the fuse, it results in increased heat generated due to resistance. Over time, this increases the temperature of the element until it melts, causing an arc of electricity through the air gap. This causes an interruption in the circuit, preventing further increase in current.

The open fuse box features a pair of contacts. When current passes through these contacts, the resistance causes heat. This heat causes the metal to melt, which results in the contacts opening and breaking the circuit. The contacts usually have a tarnished appearance, which reflects the heat that is generated as a result of an overcurrent.

Moreover, 03261.25MXP fuses feature high energy-discharging capacity. When the contacts of the fuse open, they distribute energy directly to the earth, ensuring no hazardous voltages are present in the circuit. This prevents the possibility of fires, explosions or breakdowns.

03261.25MXP fuses are highly reliable and versatile, making them ideal for many applications. They can accurately measure and trip current, thus protecting equipment from accidental overloading or potential electrical faults. The fuses are also designed to withstand the harsh conditions associated with industrial use.
