The IMO B6DR1N10-30-A is a compact and dependable Residual Current Circuit Breaker with Overcurrent Protection (RCBO) designed to protect single-phase electrical circuits against earth leakage, overload and short-circuit faults. Combining the functions of an MCB and an RCD within one 18 mm device, it provides comprehensive circuit protection while conserving valuable DIN rail space inside distribution boards and electrical enclosures.
As a Type A RCBO, the B6DR1N10-30-A can detect alternating residual currents and pulsating DC residual currents produced by modern electronic equipment. Its D curve overcurrent characteristic is intended for specialised circuits with high starting or inrush currents, helping reduce unwanted tripping when transformers, control equipment and selected motor loads are energised.
With a rated current of 10 A, a 30 mA residual operating current and a 240 V AC rated operational voltage, the B6DR1N10-30-A is suitable for industrial control circuits, machinery, transformers and other single-phase loads requiring enhanced residual current protection. Its 1P+N configuration includes the neutral connection on the left-hand side for straightforward panel installation.

Reliable Protection for High Inrush Circuits
The IMO B6DR1N10-30-A monitors the protected circuit for overloads, short circuits and residual current leakage. When a hazardous fault is detected, the RCBO disconnects the affected circuit to help protect personnel, wiring and connected equipment.
Its D curve characteristic is suited to applications where equipment may draw a significant temporary current when switched on. Type A residual current detection also provides appropriate protection for circuits containing electronic components that may generate pulsating DC leakage currents.
