Residual Current Devices, or RCDs for short, are one of those little bits of gear that make a big difference when it comes to electrical safety. At LED Controls, we know how important it is to protect people and equipment from nasty surprises like earth faults and leakage currents, so we’ve gathered a solid range of RCDs from trusted manufacturers such as ABB to help you cover every job.
When the unexpected happens and current takes a path it shouldn’t, a good RCD steps in and cuts the power fast. The models we supply meet recognised standards and give you reliable protection, whether you’re working in a commercial set-up, an industrial panel or a larger installation that needs an extra safety layer.
What you’ll find here are RCDs geared up for serious work. You’ll see two-pole and four-pole versions with different ratings, such as 63 A at 30 mA, or 125 A at 300 mA, designed to fit into modern consumer units and switchgear setups.
We know that you’re under pressure to hit deadlines and keep the build moving, so we’ve made sure our RCD range is easy to browse and pick from. If you’re not sure which one you need, or you’ve got an unusual spec and you’re looking for something specific, just give us a call. Our team will talk you through what you need to look for, check compatibility, and help you get the right device for the job.
Give us a call on 01282 242050 if you need a hand. With over 30 years in the business, we know the value of quality equipment, fair prices, fast turnaround and doing right by the customer.
A Residual Current Device, or RCD, is a safety device designed to protect people and equipment from electric shock and earth faults. It works by quickly cutting off power when it detects a leakage current, preventing harm and reducing the risk of electrical fires.
An RCD constantly monitors the electric current flowing through a circuit. If it detects a difference between the live and neutral currents, it means some current is leaking to earth, and the RCD disconnects the circuit almost instantly to keep you safe.
An RCD protects against earth leakage and electric shock, while an MCB protects against overloads and short circuits. Both are important for electrical safety and are often used together in consumer units and industrial systems for full protection.
RCDs are used in domestic, commercial, and industrial installations. They are especially important in areas where there is a higher risk of electric shock, such as outdoor circuits, wet environments, or when using portable electrical equipment.
We supply two-pole and four-pole RCDs in a range of ratings, including models such as 63 A at 30 mA and 125 A at 300 mA. These are designed to suit modern consumer units, switchgear, and industrial setups.
We offer a reliable range from trusted manufacturers such as ABB, ensuring consistent performance and compliance with recognised safety standards.
The right RCD depends on your system type, current rating, and sensitivity requirement (measured in milliamps). If you are unsure which one you need, our team can help. Give us a call on 01282 242050 and we can help you choose the correct option for your setup.
The mA rating indicates the device’s sensitivity. For example, a 30 mA RCD provides personal protection and is suitable for most general circuits, while higher ratings such as 100 mA or 300 mA are typically used for equipment or fire protection.
Yes. If your chosen model is in stock and you place your order before 3 pm, we will aim to deliver it the next working day anywhere in the UK.
