Why Choose the IMO B10R4063-30-B RCCB?

The IMO B10R4063-30-B is a high-performance Residual Current Circuit Breaker (RCCB) designed to provide advanced protection against earth leakage faults in commercial, industrial and specialist electrical installations. As part of the trusted IMO B10R RCCB series, this device offers dependable protection against alternating, pulsating DC and smooth DC residual currents, making it suitable for modern electrical systems incorporating variable speed drives, EV charging equipment and other power electronic devices.

Manufactured in accordance with IEC/EN 61008-1 and IEC 62423, the B10R4063-30-B combines robust construction with reliable switching performance. Its compact DIN rail mounted design enables straightforward installation within distribution boards and control panels while delivering long-term protection for both personnel and electrical equipment.

Featuring a 63 A rated current, 30 mA residual operating current, Type B protection and a 3 Pole + Neutral (4 Pole) configuration, the IMO B10R4063-30-B is ideal for three-phase installations requiring comprehensive residual current detection.

Key Advantages

  • Provides reliable earth leakage and residual current protection.
  • 63 A current rating for commercial and industrial electrical systems.
  • 30 mA sensitivity helps protect personnel against electric shock.
  • Type B RCCB detects AC, pulsating DC and smooth DC residual currents.
  • 10 kA conditional short-circuit rating for dependable protection.
  • Compact DIN rail mounting simplifies installation.

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 B 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 occurs, the RCCB disconnects the electrical supply rapidly, helping protect users from electric shock while reducing the risk of electrical fires caused by insulation failures.

The IMO B10R Type B series is specifically designed for installations where smooth DC residual currents may be present, making it suitable for applications involving power electronics, variable frequency drives, renewable energy systems and electric vehicle charging infrastructure.

Typical Applications

  • Commercial electrical distribution boards.
  • Industrial control panels.
  • Electric vehicle charging installations.
  • Variable speed drive systems.
  • Renewable energy installations.
  • OEM electrical equipment.
