Residual Current MCCB

Residual Current MCCBs are fundamental components in modern electrical infrastructure, providing dual protection against both overcurrent conditions and hazardous earth leakage faults. These devices are critical for preventing electrical shocks and minimizing damage to sensitive equipment and property. Our range of Residual Current MCCBs is designed and manufactured to comply with IEC60947-2, ensuring adherence to international safety and performance standards.

With frame current coverage from 125A to 800A and rated current coverage spanning 10A to 800A, these MCCBs offer versatile solutions for a wide array of applications. They are available in both 3-pole and 4-pole configurations, accommodating diverse system requirements. The rated operating voltage for these models is AC400, making them suitable for common industrial and commercial power distribution networks across Asia, Europe, South America, Africa, and Oceania.

Key features include both delayed and non-delayed operating modes for residual current protection. This flexibility allows for precise coordination within complex electrical systems, enabling selective tripping to maintain continuity of service where appropriate. Our Residual Current MCCBs are engineered for reliability and ease of integration, supporting robust electrical safety management in various sectors, from commercial buildings and data centers to manufacturing plants and public infrastructure projects. They contribute to enhanced operational safety and system uptime by quickly isolating faults.
