Our Residual Current Breaker with Over-Current Protection (RCBO) is the ultimate guardian of your electrical systems. This sophisticated device merges the protective prowess of a Residual Current Device (RCD) with the robust defense of a Mini Circuit Breaker (MCB). Specifically crafted to shield both individuals and equipment, it expertly detects dangerous residual currents and perilous over-currents, including overloads and short circuits. Ideal for residential, commercial, and industrial settings, it significantly elevates the safety and dependability of your electrical installations.
Residual Current Protection
Our RCBO is your circuit's vigilant sentinel, meticulously tracking the current flow through live and neutral wires. Under normal circumstances, these currents are perfectly balanced. However, when a leakage occurs-perhaps due to a defect in an appliance or unsafe current flowing through a person to the ground-the RCBO swiftly identifies the imbalance and instantly trips, severing the circuit to guard against electric shock. Trust in its rapid response to protect your environment.
Product Benefits :
Ingeniously designed, our channels form tunnels that ensure efficient air circulation around each pole, optimizing performance even when poles are positioned adjacently.
Enjoy the flexibility of using a Busbar and/or cable within the same terminal, guaranteeing a steadfast and reliable termination every time.
Our innovative two-step snapping mechanism ensures a seamless and secure installation on a 35mm DIN Rail, enhancing stability and efficiency.
Our RCBOs, with integrated overcurrent protection, are expertly crafted for scenarios demanding dual protection-both overcurrent and ground-fault current protection. These breakers are pivotal in swiftly detecting faults and tripping to safeguard personnel and equipment. Ideal for integration into energy management systems, automation of power supply and distribution networks, residential power surveillance, and comprehensive equipment solutions.
