Fuses

Fuses, also known as current-limiting devices, are essential components of the circuit design. To protect components from heat and overload, the fuse must be applied correctly. A 0318.375MXP is a specially designed maximum-rated current fuse with a breaking capacity of 3,000 Amps. It has a variety of application fields and a specific working principle.

Application Field

The 0318.375MXP has many application fields given its unique design and performance. It is mainly suitable for three-phase AC circuits of 400/690V, with 50/60Hz frequency, and a maximum permissible ambient temperature of 40℃. It is also equipped with an MOV over-voltage protection and MOV over-current protection. It mainly functions as a protective device for over-current and over-temperature protection, circuit switch and short circuit protection.

Working Principle

The 0318.375MXP functions as a circuit protector. It consists of a stainless steel case, a stainless steel non-sparking chamber, a thermal protector, a fusible element and a mov switch. When the current surges above the switching lower limit and the thermal protector thermal sensitivity exceeds a certain limit, the thermal protector will rapidly turn off the internal switch, cutting the power supply and eliminating the fault-caused arc in the circuit. When the fault has been cleared, the thermal protector will reset automatically to restore normal electricity supply.

Conclusion

In conclusion, the 0318.375MXP is a versatile fuse used to protect circuits from heat and overload. It has a wide range of application and powerful functions such as circuit switch and short-circuit protection. The internal working principle of the fuse utilizes a thermal protector and a mov switch to cut off power supply when necessary, ensuring reliable protection from potential danger.
