Why Choose the IMO B6DR1N20-30-A Type A RCBO?
The IMO B6DR1N20-30-A is a compact Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide dependable protection against earth leakage, overloads and short circuits in modern electrical installations. As a Type A RCBO, it detects both alternating residual currents and pulsating DC residual currents, making it suitable for circuits supplying electronic equipment, LED lighting, control equipment and variable speed devices.
Combining the functions of an MCB and an RCD within a single compact device, the B6DR1N20-30-A reduces installation space while providing complete circuit protection. Manufactured in accordance with IEC/EN 61009-1, it features a robust design, finger-safe terminals and reliable DIN rail mounting for residential, commercial and industrial applications.
With a 20 A rated current, D curve tripping characteristic, 30 mA residual operating current, 230 V AC operation and a 10 kA breaking capacity, this RCBO is particularly suited to protecting transformer-fed circuits, industrial machinery, motor control equipment and other loads with high inrush currents.
