Introduction

The 350SXMT series of electrical specialty fuses are designed to be used as protection devices for medium-voltage applications up to 600 volts. The 350SXMT fuse features two poles for safety and is UL listed and CSA certified. The 350SXMT ferrule-style fuses come in various current ratings ranging from 1 amp to 600 amps, making them suitable for a variety of applications.

Application

The 350SXMT fuse is suitable for many applications, including residential and commercial panel boards, motor controllers, transformers, and radiators. These fuses are best suited for controlling and protecting against over-currents in 600V systems and higher voltage systems. They are designed to be used in systems where the application voltage can exceed 600 volts, such as high power rectifiers, generators, and other systems that require higher voltage protection. The 350SXMT fuse is also commonly used for protecting electric motors which require special protection against high voltage.

Design

The 350SXMT fuse is designed for two pole applications. It features ceramic-style end caps that are designed to keep the fuse from opening during a fault. The fuses also feature a low-melting-point element that quickly melts when subjected to an over-current condition. The fuse element is accepted by Underwriters Laboratories (UL) and Canadian Standards Association (CSA) for tests such as interoperation, over-current, and normal mode tests. The fuse element is also impact resistant and has no over-current capability.

Materials

The 350SXMT fuse is made of copper and is available in various sizes ranging from 1 amp to 600 amps. The components of the fuse are corrosion resistant and have a high melting point. The fuse also features a high-temperature protection element.

Installation

Installation of the 350SXMT fuse can be done in two ways; either directly onto the electric box or on a separate mounting plate. The installation must be done in accordance with all applicable codes and standards. All connections must be securely tightened and the entire electrical system must be inspected before energizing the circuit. The 350SXMT fuse must be correctly aligned when mounting. The cables must be securely connected to the equipment and the cover must be firmly secured for the safety of the user.

Working Principle

The working principle of the 350SXMT fuse is based on the law of thermal conductivity. When the fuse element is exposed to a high current, it quickly melts, interrupting the flow of current and thus protecting the circuit or device. When the current returns to normal, the fusible metal alloy in the fuse element automatically reconstitutes itself and the fuse can be reused.

Conclusion

The 350SXMT series of electrical specialty fuses are designed to be used as protection devices for medium-voltage applications up to 600 volts. The fuse is easy to install and requires minimal maintenance. It is corrosion resistant, impact resistant, and has a high melting point. The fuse also features a high-temperature protection element for added safety. The 350SXMT fuse is UL listed and CSA certified, so it can be used with confidence for protecting your circuits and equipment.
