Introduction

The WRT2 series fuses are applied to a broad range of equipment such as low voltage switchgear, distribution panels, and industrial systems. By distinguishing current-limiting fuses from standard current-limiting fuses, users are able to better protect sensitive electronic devices in commercial and industrial applications. WRT2 fuses provide low melting I2t compliant with IEC Standards, while providing excellent protection against overloads and short circuits. This makes them suitable for a wide range of international regulatory and safety requirements, including applications requiring higher interrupting ratings.

Application Field

The WRT2 series fuses are designed to protect 120 to 600VAC systems with a better limiting capabilities. These fuses have outstanding current limiting performance and may prevent catastrophic equipment damage to the system that could occur due to an overload or short circuit. They are available in sizes ranging from 0.5A to 200A. Additionally, the WRT2 fuses are fitted with two short-length contacts, making them more compact, allowing for easy installation in a variety of industrial and commercial settings.

Designed with versatility in mind, WRT2 fuses are also suitable for use with various equipment types, such as motor starters, transformers, motors, control panels, switchgear, lamps, lighting, HVAC, agricultural equipment, and more. Additionally, these fuses are offered in a variety of case configurations, making them suitable for different mounting arrangements, such as plug-in and bolt-down.

Working Principle

The WRT2 series fuses use a current-limiting element to provide outstanding limiting capabilities. They can withstand interrupting ratings of up to 200kAic. This means the fuse can trip quickly in case of an overload or short circuit. The current-limiting element is combined with a temperature-sensitive tube. When a pre-set temperature is exceeded, the fuse opens quickly, thereby protecting the system.

Furthermore, the WRT2 fuses use a time-delay element that prevents the fuse from being tripped due to short circuit currents. The time delay allows the fuse to stay energized during incidental or momentary overcurrents, which may occur due to switching. This helps protect the system from unnecessary tripping.

Conclusion

The WRT2 series fuses are a great choice for protecting electrical systems in commercial and industrial settings. They provide current-limiting performance, outstanding temperature- and time-delay characteristics, and are available in a range of sizes and case configurations. This makes them an excellent choice for protecting electrical systems from potential damage due to short circuits, overloads, and other hazardous conditions.
