DZ47SD Manual Transfer Switch (solar transfer switch) is a new circuit breaker with interlocking mechanism developed by our company, the solar transfer switch adds in interlocking function based on original DZ47SD miniature circuit breakers, that is, the other side of the circuit breaker can only keep opening state when the side of the circuit breaker closing, to achieve line switching and other protection.
The solar transfer switch developed by our company has the functions of overload, short circuit protection and circuit conversion. The solar transfer switch has reasonable and reliable design, beautiful appearance and light weight. It is mainly used for switching and overload and short circuit protection of other control circuit.
DZ47SD-63 Manual Transfer Switches comply with GB10963 and IEC60898 standards.There are 6A/10A/16A/20A/25A/32A/40A/50/63A/80A/100A/125A amp transfer switches
