The 400 AMP Bussman Fusetron FRS-R-400 Time Delay is a specialized fuse designed for applications requiring overcurrent protection in electrical systems. Bussmann, a brand under Eaton, has a long-standing history in the development and manufacturing of circuit protection devices. Established in the early 20th century, the company has evolved into a leader in providing innovative solutions for electrical safety. The Fusetron series, including the FRS-R-400, was developed to cater to industries with high electrical demands such as manufacturing, oil and gas, and renewable energy. This fuse is notable for its time-delay characteristics, which provide temporary tolerance to inrush currents that are common during motor startups or transformer energization. This feature helps to prevent nuisance blowing, ensuring a more reliable operation for industrial equipment. The FRS-R-400 is constructed with high-quality materials to withstand the rigors of heavy-duty applications. It provides a current rating of 400 AMPs and is suitable for use on voltages up to 600 volts. The fuse is typically employed in residential, commercial, and industrial electrical panels, offering a high level of protection to conductors and equipment. Unique features of the FRS-R-400 include a dual-element design that combines both fast-acting and time-delay properties, which provides enhanced protection for a variety of applications. The indicator window on the fuse allows for easy visual confirmation of operation status.
