Fused switches disconnectors/switch fused isolators are devices used to ensure that a circuit is completely powered down in order for it to be serviced or maintained. They isolate a given part of the circuit by cutting off its electrical supply, making it safe for service or maintenance. You can find out more in our [guide to isolators and switch disconnectors](/web/content/discovery/ideas-and-advice/isolators-switch-disconnectors-guide).

Fused switches contain multiple fuses inside the same enclosure so that it is easy to select and isolate a particular part of the circuit. For example, an isolator switch can be used in a substation to physically disconnect any circuit when repairs are being carried out.

### **What are fused switch disconnectors used for?**

Fused switches protect workers performing maintenance on part of an electrical circuit as well as preventing damage to the circuit itself. The advantage of using a fused switch over a non-fused switch is that it can provide a higher level of safety compared with unfused disconnectors, as the fuse blows in the event of breaches such as short circuits or over currents. This makes it certain that that part of the circuit cannot have current flowing through it while being worked on.

### **Types of fused switch disconnectors**

Fused switches mainly differ depending on the type of fuses they house, the number of poles they have, and the terminal type.

### **Advantages of Fuse Switch Disconnectors**
- High safety and reliability.
- Top performance.
- Easy installation and commissioning
- Suitable for diverse application
- A high degree of protection
- Suitable for diverse applications

###  **Applications for Fuse Switch Disconnectors**
- Construction
- Pharmaceuticals
- Agriculture
- Healthcare
- Education
- Data Centres
- Airports
- Manufacturing

<p>Take safety to a whole new level with Fused Switch Disconnectors from Eaton. Here at RS we have an extensive selection of FSD's to choose from so you can find the perfect fit for your application.</p><h2>What's Fuse Switch Disconnector and how do they work?</h2><p>A Fused Switch Disconnector (FSD) is an electrical device which combines the functionality of a fuse, a switch, and a disconnector, all in one handy package. They are used in power distribution systems as a means to manage and protect electrical circuits. An FSD allows for safer operation and maintenance, as they work by isolating specific circuits and equipment from the power supply. The fuses within this device provide protection as they will blow when short-circuits and overcurrents occur, while the disconnector is there to ensure that the electrical circuit is completely isolated from the power source. They allow a high degree of manual control due to the switch function, as it can be turned off or on. You'll find these units commonly used in sectors such as manufacturing, healthcare, construction, oil and gas, agriculture, and data centres. Compared to non-fused switches they provide a higher level of safety.</p><p>Explore popular ranges from Eaton such as the Glasgow, Excel 2, T0, DMM, P1 and P3 families of fused switch disconnectors. These models include features such as sturdy rust-protected enclosures, high IP ratings, surface mounting, screw type connections, and user-friendly rotary handles. Single-pole, double-pole and triple-pole options are available.</p><p>Eaton are the global powerhouse in power management. They have over a century of experience at designing solutions to help upgrade safety, efficiency, and sustainability in how we live and work. In today's fast changing world, you can rely on Eaton's dependable and high-quality FSD's for enhanced protection of your electrical circuits.</p>

ABB OT Switch Disconnectors | RS

<p>ABB OT switch disconnectors vary from 160A to 3150A (Amperes). They are largely used as the primary switch in low voltage switchgears which, ultimately, distribute the power, stopping and starting motors and isolating loads during maintenance. The OT range of switch disconnectors from ABB are suitable for diverse applications such as motor control centres, switchboards and automatic transfer applications.</p><h2>Why choose an OT switch disconnector from ABB's range?</h2><p>ABB OT switch disconnectors are reliable in extreme conditions and are designed, built and tested for the best possible performance. They are designed to be virtually maintenance free across their entire lifespan and are a durable, reliable choice. ABB OT switch disconnectors have also been designed with practicality in mind, with a space saving design and an easy and cost-efficient installation. They are extremely versatile in terms of installation orientation and work just as well whether installed horizontally or vertically.</p><h3>How do I select an OT switch disconnector from ABB's range?</h3><p>When choosing the correct product for your application, it's important to consider a number of factors that will ensure the safe running of your application and any workers involved:</p><h4>Calculate voltage and current requirements</h4><p>It's important to accurately calculate the applications voltage and current requirements, as going higher than the required voltages poses a significant risk of an arc flash, which can lead to serious operator injury, or even death. If your current is higher than the switch disconnector can accommodate, you will need stronger contacts to support the application. Skipping this step could result in system overheat.</p><h5>Consider your application type</h5><p>Determining whether you are installing a switch disconnector for a single-motor or combined load application will help dictate the kind of switch required.</p><h6>Determine your mounting style</h6><p>Where do you want to install your switch disconnector and which mounting type is the most suited to your application?</p>
