Why Choose the IMO B10R2040-30 Residual Current Device?
The IMO B10R2040-30 is a dependable Type AC Residual Current Device (RCD/RCCB) designed to provide reliable protection against earth leakage faults in single-phase electrical installations. Manufactured by IMO Precision Controls, it forms part of the trusted B10R RCCB series, offering dependable protection for commercial, industrial and residential distribution systems.
The device continuously monitors the current flowing through the live and neutral conductors. If an earth leakage fault creates an imbalance greater than the rated residual operating current, the RCD disconnects the supply, helping reduce the risk of electric shock and protecting electrical installations from insulation faults and leakage currents.
With a 40 A rated current, 30 mA residual operating current, 1 Pole + Neutral configuration and 230/400 V AC operation, the B10R2040-30 provides dependable protection for modern electrical installations while allowing straightforward DIN rail installation.
Key Advantages
- Reliable Type AC residual current protection for electrical installations.
- 40 A rated current for higher load circuits.
- 30 mA residual operating current for enhanced personnel protection.
- Type AC protection for alternating sinusoidal residual currents.
- 10 kA conditional short-circuit rating.
- Compact DIN rail mounting for quick installation.
Key Features
- IMO B10R residual current device series.
- 40 A rated operational current.
- 30 mA rated residual operating current.
- Type AC residual current characteristic.
- 1 Pole + Neutral (2 Pole) configuration.

- DIN rail mounting to EN 60715.
Reliable Earth Leakage Protection
Residual current devices compare the current flowing through the live conductor with the current returning through the neutral conductor. Under normal operating conditions these currents remain balanced. If current leaks to earth because of damaged insulation or accidental contact, the RCD rapidly disconnects the electrical supply to improve safety.
The Type AC characteristic is designed for circuits carrying alternating sinusoidal residual currents commonly found in standard electrical installations. The device should always be installed alongside suitable overcurrent protection, as it does not provide overload or short-circuit protection.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels.
- Residential consumer units.
- Machinery and equipment power supplies.
- OEM electrical installations.
- General earth leakage protection circuits.
