Type B RCCB

ML60-B

B-type RCCB is designed according to standard IEC/EN61008-1 + IEC/EN62423. The ML60-B RCCB type B can detect high-frequency AC and smooth DC earth residual currents. It's also named "universal current sensitive RCCB", which means could be used for the widest variety of applications like variable speed drives, PV systems, and EV charging stations and is always designed for use under harsh ambient.
