355LMT Application Field and Working Principle

Electrical, Specialty Fuses are designed for a variety of specialized applications where a higher current rating than a standard fuse is required for safety or performance reasons. The 355LMT is suitable for use in an array of electrical applications, providing protection up to 600V and 8A. It is a single-ended fuse with a clear thermoplastic design which allows for easy visibility of the fuse link.

Overview

The 355LMT is designed to provide overcurrent protection against short-circuit and overload conditions. It is UL/CSA/CE approved, and is rated for up to 8A 250V AC or 6A DC. The 355LMT has a radial construction with two contacts and an integral mounting bracket for easy installation in a wide variety of applications. It features a clear thermoplastic material which provides clear visibility of the fuse link and it is pre-scored at two contact points to allow for easy replacement in the event of a blown fuse. The fuse link is nickel-plated and the contact surfaces are gold-plated to ensure good electrical contact and reliable performance.

Working Principle

The 355LMT fuse operates on an interrupting principle which is based on melting of the fuse link at a predetermined temperature. This occurs when the current passing through exceeds the rating of the fuse, causing the link to melt and quickly discharge any excess energy or heat. This protects the circuit from further damage.

The fuse’s thermal properties, such as melting point, response time, and energy rating, are designed in a way that reflects the expected loading of the circuit. The operating point of the fuse is set by adjusting the contact material and contact spacing, therefore, providing the specific level of protection for the circuit.

Typical Applications

The 355LMT is a versatile fuse and is suitable for general purpose applications as well as a variety of specialized uses. Its clear thermoplastic design makes it well-suited for use in medical and dental equipment, consumer electronics, automotive and marine applications, electro-mechanical equipment and other high-current applications. It is also suitable for use in battery chargers and power supplies.

Advantages

The 355LMT fuse has a number of distinct advantages over conventional fuses. These include a clear thermoplastic design which is shatterproof. It also has an integrated mounting bracket which allows for easy installation. The contact surfaces are gold-plated, which improves electrical contact and enhances reliability. Its UL/CSA/CE approval further add to its suitability for use in a vast array of applications.

Conclusion

The 355LMT fuse is a versatile and reliable fuse, suitable for wide variety of applications. It is UL/CSA/CE approved and is designed to provide overcurrent protection against short-circuit and overload conditions. Its clear thermoplastic design and integrated mounting bracket make it well-suited for use in medical and dental equipment, consumer electronics, automotive and marine applications, electro-mechanical equipment and other high-current applications. It also features gold-plated contacts which improve electrical contact and enhance reliability.
