Residual Current Monitoring & Protection
Electrical Protection in Digital Energy Era
With increaseing use of power electronics equipment, the traditioal Type AC reisidual current devices can not provide sufficient protection against electrical shock and fire. Bituo offers adanvanced Type A / F / EV / B technologies that can be integrated into your products and systems, so as to make electricity safter with our customers and partners.
The total market share of Type A, F, EV and B RCDs is less than five percent in Asia, Latin America and Afria – exposing large safety gap at home
Less than 30% of Mode-2 / 3 EV chargers worldwide have proper DC fault current protection compliant to IEC 62955 and UL 2231.
Worldwide at least 6,000 electrical accidents – such as shock and fires- should not have happened, if the right RCDs are well deployed.
*Notes: the above number was estimated based on the data collected from third-party reports and articles for the year of 2021.
