Fuses are components designed to protect equipment from excessive electric current, which can cause fires, equipment malfunction, and equipment damage. They are designed to provide short circuit current protection for various applications, such as circuits driving motors, equipment powering up, short wave circuits, high-frequency components, and power sources. This article will discuss the application fields and working principle of the 0318.250MXP fuse.

Application Fields

The 0318.250MXP fuse is an SB Fuse designed for use in high load switching applications, 90 amperes, 28Vdc. The fuse is UL Recognized, CSA Certified, and TUV approved. It is well suited for use in industrial and professional applications, such as those related to motors, high current electrical equipment, and applications involving sensitive and expensive components.

Specifications

The 0318.250MXP fuse has a Rated Voltage of 28Vdc with an Operating Limit of up to 28V. The maximum Surge Voltage is 50Vdc and the Minimum Operating Current (MOM) is 15A. It has a thermal breakdown of up to 90A. Its body composition is composed of metal oxide, and its base material is composed of glass. The rated insulation is UL 94V-2.

Working Principle

The 0318.250MXP fuse has an exceptionally low time-delay characteristic, which provides a fast short-circuit protection in the event of an overcurrent. In normal operation, the contact melts and opens the circuit, thus interrupting the current. The fuse dissipates the stored energy from the circuit and maintains the fault until it is cleared. The fuse is designed to operate in temperatures ranging from -55°C to +125°C.

The fuse is rated for a maximum continuous current of 90A, with the maximum operating temperature of 125°C. The fuse is rated for both DC and AC applications. This fuse has a rated temperature rise of only 62°C at 90A. The time-delay of the fuse compared to a 10A slow-blow type fuse is nearly 30% faster. Its high rating and short time-delay make it suitable for motor circuit protection.

In conclusion, the 0318.250MXP fuse is ideal for high load switching applications. It is rated for up to 90 amperes, and its thermal breakdown is up to 28Vdc. The fuse has an exceptionally low time-delay characteristic, making it suitable for motor circuit protection. It is UL Recognized, CSA Certified, and TUV approved.
