Why Choose the IMO B10R2063-30-B Type B Residual Current Device?

The IMO B10R2063-30-B is a high-performance Type B Residual Current Device (RCD/RCCB) designed to provide comprehensive earth leakage protection in modern single-phase electrical installations. Its advanced residual current detection makes it suitable for circuits containing power electronics, inverters and equipment capable of producing AC, pulsating DC or smooth DC leakage currents.

The device continuously compares the current flowing through the live conductor with the current returning through the neutral conductor. When an earth leakage fault creates an imbalance above the rated operating threshold, the RCCB disconnects the electrical supply, helping reduce the risk of electric shock, equipment damage and electrically initiated fires.

Featuring a 63 A rated current, 30 mA residual operating current, 1 Pole + Neutral configuration and a 10 kA rated conditional short-circuit current, the B10R2063-30-B is particularly suited to EV charging equipment, solar photovoltaic systems, variable-speed drives, UPS installations and other electronically controlled loads.

Key Advantages

  • Advanced Type B residual current protection.
  • Detects AC, pulsating DC and smooth DC residual currents.
  • 63 A rated current for higher-load electrical circuits.
  • 30 mA sensitivity for additional protection against electric shock.
  • Suitable for inverter-driven and power-electronic equipment.
  • 10 kA rated conditional short-circuit current.
  • Compact DIN rail design for efficient panel installation.

Key Features

  • IMO B10R residual current circuit breaker series.
  • Type B residual current characteristic.
  • 63 A rated operational current.
  • 30 mA rated residual operating current.
  • 1 Pole + Neutral (2-pole) configuration.
  • Suitable for AC and DC-sensitive applications.
  • Integrated test button for routine functional checks.
  • DIN rail mounting to EN 60715.

Comprehensive Type B Earth Leakage Protection

Conventional Type AC and Type A residual current devices are not designed to detect every form of leakage current that may be generated by modern power-electronic equipment. Smooth DC residual current can saturate the sensing mechanism of an unsuitable RCD, potentially preventing reliable operation during an earth fault.

The Type B characteristic of the IMO B10R2063-30-B provides enhanced detection across a broader range of residual-current waveforms. This includes sinusoidal AC, pulsating DC, composite-frequency and smooth DC leakage currents associated with rectifiers, inverters, frequency converters and electronically controlled equipment.

Its 30 mA residual operating current provides additional protection against electric shock where a Type B device is required by the equipment manufacturer, installation design or applicable wiring regulations. As an RCCB, it does not provide independent overload or short-circuit protection and must be used with an appropriately rated MCB, MCCB or fuse.

Typical Applications

  • Electric vehicle charging equipment.
  • Solar photovoltaic inverter systems.
  • Variable-speed and variable-frequency drives.
  • Uninterruptible power supply systems.
  • Battery storage installations.
  • Industrial frequency converters.
  • Machine tools and automated machinery.
  • Commercial and industrial distribution boards.

Frequently Asked Questions

What is the IMO B10R2063-30-B used for?

The B10R2063-30-B provides earth leakage protection for circuits containing equipment that may generate AC, pulsating DC or smooth DC residual currents.

What does Type B mean?

Type B means the RCCB can detect sinusoidal AC, pulsating DC and smooth DC residual currents, making it suitable for inverter-based and power-electronic equipment.

What is the rated current of the B10R2063-30-B?

The IMO B10R2063-30-B has a rated operational current of 63 A.

Does the 30 mA rating provide additional personal protection?

Yes. A 30 mA residual operating current is commonly used to provide additional protection against electric shock, subject to the installation design and applicable electrical regulations.

Is the B10R2063-30-B suitable for EV charging?

It can be suitable for EV charging installations requiring Type B residual current protection. The charging equipment manufacturer's instructions and applicable wiring regulations must always be followed.

Can it be used with solar photovoltaic systems?

Yes. Type B RCCBs are commonly used where solar inverters or associated equipment may generate smooth DC or mixed-frequency residual currents.

Does this RCCB provide overload protection?

No. The B10R2063-30-B provides residual current protection only and must be installed with a suitably rated circuit breaker or fuse for overload and short-circuit protection.
