The IMO B6BR1N25-30 is a high-performance 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 RCCB and miniature circuit breaker into one compact unit, it delivers comprehensive circuit protection whilst reducing installation space within distribution boards.
Featuring a 25 A rated current, 30 mA residual operating current, Type AC residual current protection and a B curve tripping characteristic, the B6BR1N25-30 is ideal for socket outlet circuits, lighting, commercial installations and general-purpose electrical applications where dependable protection is essential.
Manufactured in accordance with IEC 61009-1, the device incorporates a 1 Pole + Neutral (1P+N) configuration, 10 kA short-circuit breaking capacity, compact DIN rail mounting and an integrated test button for straightforward routine testing of residual current protection.

Comprehensive Circuit Protection
The IMO B6BR1N25-30 continuously monitors electrical circuits for overload conditions and residual current leakage. Should either fault occur, the RCBO disconnects the supply rapidly, helping protect personnel, electrical wiring and connected equipment from damage or electric shock.
Its B curve operating characteristic makes it particularly suitable for lighting, socket outlets, building services and control circuits where relatively low inrush currents are expected. Combining residual current and overcurrent protection into one compact device also simplifies installation and reduces the number of protective devices required.
