The IMO B6DR1N06-30-A is a compact Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to provide reliable 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 systems and other sensitive electrical loads. Manufactured in accordance with IEC/EN 61009-1, it delivers dependable protection for residential, commercial and industrial applications.
The B6DR1N06-30-A combines the functions of an MCB and an RCD within a single compact device, reducing DIN rail space while simplifying installation and maintenance. Its finger-safe terminals, contact position indicator and robust construction provide long service life and dependable operation in demanding environments.
With a 6 A rated current, D curve tripping characteristic, 30 mA residual operating current and 230 V AC operation, this RCBO is ideal for protecting specialised circuits with high inrush currents, including transformers, industrial control equipment and selected motor applications.
