DW17 Universal Circuit Breaker

Application:

DW17 series low voltage universal circuit breakers are suitable for the distribution circuits with AC 50/60Hz, voltage 380V & 660V,
current up to 5000A, used as distributing electric energy and protecting circuit and electrical equipment against the overload,
voltage drops and short circuit. It also can be used as unfrequent changeover of circuit under normal conditions. The circuit breaker
less than 1250A can be used as protecting motor against overload short circuit in circuit with AC 50/60Hz voltage 380V & used as
unfrequent starting motor under normal conditions.
