Why Choose the IMO B10R4063-30-A RCCB?
The IMO B10R4063-30-A is a high-performance Residual Current Circuit Breaker (RCCB) designed to provide reliable protection against earth leakage faults in commercial, industrial and electrical distribution installations. As part of the trusted IMO B10R RCCB series, this device delivers dependable residual current protection while helping safeguard people and equipment from electric shock and insulation faults.
Manufactured in accordance with IEC/EN 61008-1, the B10R4063-30-A combines robust construction with dependable switching performance. Its compact DIN rail mounted design allows quick installation within distribution boards and control panels, making it suitable for new installations and electrical upgrades.
Featuring a 63 A rated current, 30 mA residual operating current, Type A protection and a 3 Pole + Neutral (4 Pole) configuration, the IMO B10R4063-30-A is ideal for protecting three-phase electrical circuits where detection of alternating and pulsating DC residual currents is required.
Key Advantages
- Provides reliable earth leakage and residual current protection.
- 63 A current rating suitable for commercial and industrial installations.
- 30 mA sensitivity helps protect personnel against electric shock.
- Type A RCCB detects AC and pulsating DC residual currents.
- 10 kA conditional short-circuit rating for dependable protection.

Key Features
- IMO B10R residual current circuit breaker series.
- 63 A rated current.
- 30 mA residual operating current (IΔn).
- 230/400 V AC operating voltage.
- 3 Pole + Neutral (4 Pole) configuration.
- Type A residual current protection.
- 10 kA conditional short-circuit capacity.
- DIN rail mounting with IP20 protection.
Reliable Residual Current Protection
Residual Current Circuit Breakers continuously monitor the balance between live conductors and neutral. If an earth leakage fault is detected, the RCCB disconnects the electrical supply rapidly, helping protect users against electric shock while reducing the risk of electrical fires caused by insulation failures.
The IMO B10R series provides dependable protection for modern electrical installations and is suitable for use with three-phase systems requiring Type A residual current detection for both alternating and pulsating DC leakage currents.
Typical Applications
- Commercial electrical distribution boards.
- Industrial control panels.
- Three-phase machinery protection.
- Manufacturing facilities.
- Building services installations.
- OEM electrical equipment.
