Why Choose the IMO B10R2040-100-A Type A Residual Current Device?
The IMO B10R2040-100-A is a high-quality Type A Residual Current Device (RCD/RCCB) designed to provide dependable protection against earth leakage faults in single-phase electrical installations. Manufactured by IMO Precision Controls, it forms part of the proven B10R RCCB series, offering reliable protection for industrial control panels, commercial distribution systems and machinery.
The device continuously monitors the current flowing through the live and neutral conductors. If an earth leakage fault causes an imbalance above the rated residual operating current, the RCD disconnects the supply, helping reduce the risk of electric shock and equipment damage. Its Type A characteristic enables detection of both AC and pulsating DC residual currents, making it suitable for modern electronic loads and industrial equipment.
With a 40 A rated current, 100 mA residual operating current, 1 Pole + Neutral configuration and a 230 V AC operating voltage, the B10R2040-100-A delivers dependable earth leakage protection while offering straightforward DIN rail installation in electrical distribution equipment.
Key Advantages
- Reliable Type A residual current protection for industrial and commercial installations.
- 40 A rated current for higher load circuits.
- 100 mA residual operating current for earth leakage protection.

Reliable Earth Leakage Protection
Residual current devices monitor the balance between live and neutral currents. When current leaks to earth because of damaged insulation, faulty equipment or accidental contact, the device disconnects the supply within milliseconds to help improve electrical safety.
The Type A characteristic allows the IMO B10R2040-100-A to detect both sinusoidal AC and pulsating DC residual currents, making it suitable for installations supplying modern electronic equipment, industrial controls and automation systems. The device should always be installed alongside appropriate overcurrent protection.
Typical Applications
- Industrial electrical distribution boards.
- Commercial electrical installations.
- Industrial machinery and automation systems.
- Control panels and switchboards.
- OEM electrical equipment.
- General earth leakage protection circuits.
