3JS 350-R TR Fuses

Fuses are found in practically every electrical circuit, from household wiring to industrial applications, for the purpose of protection of line conductors and components, as well as to regulate electrical circuits. The 3JS 350-R TR is a medium-voltage fuse with a time-delay rating designed for use in indoor or outdoor service-entrance protection and high performance motor control applications.

Application Field and Working Principle

The 3JS 350-R TR fuse offers a combination of features designed to provide superior performance for service-entrance protection and motor control applications. This fuse is rated at 10kVAC, and its time-delay rating is such that it can respond quickly to short-circuit levels, yet still have sufficient time delay to protect against overload. Its reversible bolt-on profile allows it to easily retrofit in existing service-entrance blocks.

Fuses work by containing a small element inside its body, typically a wire or strip, which is designed to heat up and melt under an overcurrent condition, protecting the device or line connected to it from possible damage. In the case of the 3JS 350-R TR fuse, the element is metal-oxide. This type of element has the unique ability to respond quickly to short-circuit currents or other overcurrent conditions, while providing sufficient time delay to protect against overloads or other prolonged abnormally high currents. This allows users to rest assured that their equipment will be adequately protected against surges and overcurrents without sacrificing performance.

The 3JS 350-R TR fuse also features a UL listing, class RK5 rating, and a RoHS-compliant construction. This offers users the peace of mind that the fuse they’re using offers the highest level of safety and reliability. The UL listing ensures that the fuse meets the strict standards for installation and use outlined by the organization.

The 3JS 350-R TR fuse is designed for use in a variety of applications, such as motor control circuit protection, capacitor bank protection, process industry motor controls, lamps and lighting, capacitive loads, and other medium voltage installations, making it an ideal choice for a wide variety of uses.

The 3JS 350-R TR fuse is a reliable, efficient, and cost-effective choice for a variety of applications, and its features and benefits make it an attractive choice for any user looking to protect their device or line from possible overcurrent conditions. Its time-delay rating allows it to respond quickly to short-circuit levels and yet still have sufficient time delay to protect against overloads.
