<p>An RCCB or residual-current circuit breaker is a safety device used to protect electrical circuits. RCCBs protect people from electric shocks, and electrocution and help prevent electrical fires.</p><p>RS offers an extensive range of high-performance RCCBs and RCDs from leading brands including ABB, Schneider Electric, and Siemens.</p><h2>How does an RCCB work?</h2><p>An RCCBs incoming current must equal the outgoing current in any circuit. RCCBs can compare the difference in current values between the live and neutral wires. When appliances are working correctly all current entering the appliance through the live wire leaves the appliance via the neutral wire. If a fault occurs some current can flow through the earth wire if there is no earth this can even flow through you. This results in the unequal current flow coming into the device to what is going out, this difference is referred to as residual current.</p><h2>What is the difference between an RCCB and an RCD?</h2><p>An RCD (residual current device) can keep an electrical system safe by preventing fatal electrical shocks. RCDs can also provide protection from electrical fires. An RCCB is essentially an RCD minus the overload protection. They are typically used in applications where the risk of electric shock is limited. For more detailed information, please see our in-depth <a href="/web/content/discovery/ideas-and-advice/rcd-guide">RCDs guide</a>.</p><h2>What are the different types of RCCB and RCD?</h2><p>RCCBs and RCDs are usually mounted on DIN rail. They can be 2, 3, or 4 poles. Varying in current ratings, trip sensitivity, and tripping characteristics. All these specifications should be carefully considered depending on your individual needs and application.</p>

<p>Please view our high-performance Schneider Electric RCCB Range, available for next day delivery!</p><p>A residual-current circuit breaker (RCCB) is used to protect against the user from electrocution, electric shocks and the prevention of electrical fires. RCCB|s work by comparing the difference between neutral and live wires in current values. If all currents enter the contactor through live wire and exit by neutral wire, this shows that the RCCB Is working correctly. When working incorrectly the current may travel through the earth wire which can result in an electric shock if there is no earth. An inadequate current flow is known as a residual current, In most cases if there is an earth fault an RCCB can handle a fault of up to 1kA.</p><p>Our Schneider Electric RCCB range comes with a different series, with either 2, 3 or 4 poles and vary in current ratings, tripping characterises and trip sensitivity. We advise that all of these areas need to be carefully considered before using the product.</p><p>It is recommended that RCCB|s are used along side MCB|s to ensure ultimate protection, Please take a look at our Schneider Electric MCB range.</p>

ABB Type B RCCBs | RS

<p>In partnership the technology giant ABB, we bring you a high-quality, reliable, and high performing range of Type B RCCBs. Type B RCCBs are one type of residual current circuit breakers, that can be used to protect electrical circuits and any workers that may be conducting maintenance on a circuit. An ABB Type B RCCB ensures tripping for smooth DC currents, pulsating DC currents and residual AC currents.</p><h2>What does an ABB Type B RCCB do compared to an ABB Type A RCCB?</h2><p>On the one hand, ABB Type B RCCBs ensure residual AC currents, as well as pulsating and smooth DC currents are protected from tripping. On the other hand, Type A RCCBs ensure tripping protection for residual AC currents and pulsating DC currents.</p>

ABB Type A RCCBs | RS

<p>Please browse ABB's range of high-quality Type A residual current circuit breakers (RCCBs). RCCBs are used to protect electrical circuits, as well as any workers who may be conducting maintenance tasks on a particular circuit. An ABB Type A RCCB specifically protects against AC and pulsating DC leakage currents.</p><h2>What is the difference between a Type A and Type B RCCB?</h2><p>Type A RCCBs ensure protection from tripping for pulsating DC currents and residual AC currents, whereas Type B RCCBs ensure protection from tripping for both smooth and pulsating DC currents, as well as residual AC currents.</p>

<p>Guard against leakage current in your electrical system with a Residual Current Device from Eaton. Here at RS we have a vast choice of Eaton RCDs, so you can find one that perfectly suits your requirements.</p><h2>What is an RCD?</h2><p>A Residual Current Device (also known as an RCD) is a highly important safety device which constantly monitors circuits to detect leakage current. When it detects that there is an electrical imbalance, for example a faulty appliance or a person touching a bare wire, it will disconnect the circuit. This helps to minimise the risk of dangerous electric fires or shocks. They don't protect against overcurrent or short-circuiting.</p><p>You can use these units in many residential and industrial applications. There are different types available which are suited to particular environments, for example fixed RCDs, socket outlets with integrated RCDs, and portable RCDs are often used in domestic areas, while Type A, F, B, and AC versions are more suited for industrial installations.</p><h3>How often should I test an RCD?</h3><p>You should test fixed and socket RCDs roughly every 3 months, whilst portable RCDs should be test upon every use. Often you will find that most units have a built-in 'test' button for this, making it a quick and simple task.</p><p>Eaton's offer here at RS includes the PKNM and PFIM series. You can select models with features and advantages such as contact position indicators, 2 to 4 poles, preventive information, fault status display with LEDs, DIN rail mounting, reduced nuisance tripping, and automatic re-setting, among others.</p><p>Eaton are a leading global power management company with over 100 years of experience creating products to help people live and work more safely, efficiently, and sustainably.

ABB RCCB | RS

RCCBs (also known as residual-current circuit breakers) are used to provide protection for electrical circuits themselves, as well as the workers who may be conducting maintenance works on the circuit. RCCBs offer protection from electrocution and electric shocks and also help to prevent electrical fires. In partnership with ABB, we bring you a high-quality range of reliable, high performing RCCBs.<p>RCCBs work by comparing the difference in current values between neutral and live wires. Therefore, an RCCBs incoming current must match a circuits outgoing current. In a working circuit, current entering the appliance will pass through the live wire and leave through the neutral wire. If a fault occurs, some current can flow through the earth wire, or even someone performing work on the circuit. This results in unequal current flow, known as residual current. </p>An ABB RCCB will work to automatically measure and disconnect the circuit whenever a fault occurs, or the current exceeds the rated sensitivity.<h2>What are the main benefits of an ABB RCCB?</h2>An RCCB purchased from ABB's extensive range ensures worldwide safety performances, certified by international marks approval. The devices also offer high quality execution and attention to details.<h2>What is the difference between an RCCB and an MCB?</h2>MCBs protect against short circuit and overload current, whilst RCCBs only protect from electric shock and earth leakage. In an ideal electrical circuit, both should be used in unison, to offer protection from all angles.<h2>Features & Benefits</h2><ul><li>Compact design makes ABB RCCBs easy to install.</li><li>Electrical and mechanical endurance to function efficiently in many operations.</li><li>Fast response time which provides rapid protection against electric shocks.</li></ul><h2>Applications</h2><ul><li>Commercial buildings</li><li>Residential buildings</li><li>Hospitality</li><li>Industrial buildings</li><li>Healthcare and hospitality facilities</li></ul>
