Why Choose the IMO B6DR1N32-30-A Type A RCBO?
The IMO B6DR1N32-30-A 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 MCB and an RCD within one device, it provides comprehensive circuit protection while simplifying installation inside distribution boards, control panels and electrical enclosures.
As a Type A RCBO, the B6DR1N32-30-A detects both alternating residual currents and pulsating DC residual currents. This makes it suitable for modern installations containing electronic controls, LED drivers, switched-mode power supplies, automation equipment and other loads that may generate pulsating DC leakage currents.
With a 32 A rated current, D curve tripping characteristic, 30 mA residual operating current and 10 kA short-circuit breaking capacity, this RCBO is particularly suited to demanding circuits with high starting or inrush currents. Typical applications include transformers, industrial machinery, motor control equipment and specialised commercial or industrial loads.

Reliable Protection for High Inrush Loads
The IMO B6DR1N32-30-A continuously monitors the protected circuit for excessive current and residual earth leakage. When a hazardous overload, short circuit or leakage condition is detected, the device disconnects the affected circuit to help protect personnel, electrical wiring and connected equipment.
Its D curve characteristic permits a higher temporary starting current than conventional B or C curve devices. This helps prevent nuisance tripping when equipment such as transformers, motors, solenoids or industrial power supplies is energised, while still providing dependable protection under sustained fault conditions.
Typical Applications
- Industrial control panels.
- Transformer-fed circuits.
- Motor and solenoid circuits.
- Industrial machinery.
- Automation and production equipment.
- Commercial distribution boards.
- Electronic power supplies.
- OEM equipment and machine-building applications.
