Electrical, Specialty Fuses

Made in the United States for applications in North America, the RJS 2.5-R SHORT is a fused electrical disconnect switch rated 25A with a voltage of 240V. It serves as a primary or secondary protection device, serving to break or create a circuit in order to control and protect electrical systems. In the event of a short circuit, the fuse element heats up and breaks the circuit, protecting the device from dangerous and costly short-circuits that can lead to building fires. The 2.5-R SHORT also serves as an electro-mechanical interlock that prevents accidental energization of a circuit or system.

Working Principle

The fuse element is made of a non-conductive material and is housed within an electrically insulated enclosure. Fused disconnects with a short element have a fixed contact between the incoming and outgoing terminals. When an overload occurs, the fixed contact melts, creating an arc and breaking the circuit. In addition, an indicator light is connected electrically from the incoming side to the outgoing side. This indicator light is wired in series with the fuse, and when the contact melts, the light will not illuminate, which serves as a visible warning to personnel of the overloaded state.

Applications

The RJS 2.5-R SHORT fused disconnect is suitable for industrial, commercial and residential applications such as electric motors, industrial automation, HVAC, and lighting systems. It is a cost-effective solution for controlling and protecting switchgear, panelboards, metering equipment, motor circuits, and other electrical systems from short-circuits. The regular and short models can be wall-mounted and flush-mounted. These fused disconnects are also UL listed for installation and use in hazardous locations.

Main Features

• Rated 25A (250 VAC)
• UL Listed
• Short element for added protection
• Electro-mechanical interlock
• Visible indicator light
• Also available with din rail mounting

The RJS 2.5-R SHORT fused disconnect is a reliable and cost-effective device for controlling and protecting electrical systems in industrial, commercial and residential applications. It is a UL listed product with a short element for added circuit protection. It also provides an electro-mechanical interlock and visible indicator light to alert personnel of an overloaded condition. With the ability to be flush and wall mounted, the 2.5-R SHORT is an overall versatile device for creating and breaking circuits.
