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.
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.
