AC Series Products include AC MCB, AC MCCB,AC SPD, AC Isolator and Dual Power Transfer Switch, all the products use for the AC side of the photovoltaic system, have the functions of short circuit, overload, lack of phase, fault and other protective.
AC MCB（Mini circuit breaker) is used in lighting distribution system or motor distribution system for protecting overload and short circuit in the system. The product is neoteric in structure, light in weight, reliable and excellet in performance. Its frame and parts adopt plastics of high fire resistant and shockproof. The product, with long life, is mainly used in AC 50Hz single pole 240V or two, three, four poles up to 415V circuit for overload and short circuit protection, as well as for unfrequently switching electric equip ment and lighting circuit in normal case.
AC MCCB（Moulded case circuit breaker) is a new type product developed and manufactured by Adopting international advanced technology. It is supplied with rated insulation voltage 800V and used for circuit of AC 50Hz, rated operation voltage AC 400V or below rated operation current up to 1600A for infrequent changing over and starting of the motors. Equipped with the protection devices for over-current, short circuit and under voltage, the product is capable of preventing damage of circuits and supply units. The product conforms to IEC60947-2 standard.
AC Surge Protective Device (SPD), used in the 50/60HZ AC power system with rated voltage of 220V to 380V (or communication system), indirect and direct effects on the lightning surge overvoltage of lightning or other transient protection, suitable for family housing, the third industry and the industrial field of surge protection requirements.
Dual Power Transfer Switch (hereinafter referred to as switch) in applicable to AC 50Hz or 60Hz, rated operating voltage 400V, rated operating current 63A or below double-loop power supply system, the conversion to the selectivity between the two-way power supply according to the requirements, the product with short circuit, overload, under voltage, voltage loss protection function, also with prepared the fire, double points and output switching signal function. Especially suitable for the need to have fire protection requirements of office buildings, shopping malls, Banks, railway stations, hospitals and high-rise building to install fire lighting circuit.
