DC Series Products include DC MCB, DC MCCB, DC SPD, DC Fuse, DC Isolator, Solar Fuse Connector and Solar Diode Connector, all the products use for the DC side of the photovoltaic system, have the functions of short circuit, overload, lack of phase, fault and other protective.
DC MCB（Mini circuit breaker) supplementary protectors are designed to provide over current protection within appliances or electrical equipment, where a branch circuit protection is already provided or not required. Devices are designed for direct current (DC) control circuit applications.It’s din rail mounted type and Current form 1A to 63A and voltage form 12VDC to 1000VDC.
火拼斗牛DC MCCB（Moulded case circuit breaker)supplementary protectors are designed to provide over current protection within appliances or electrical equipment, where a branch circuit protection is already provided or not required。 Devices are designed for direct current (DC) control circuit applications。It’s din rail mounted type and Current form 1A to 63A and voltage form 12VDC to 1000VDC。
Surge protective device, protect against lightning surge voltages in solar system (photovoltaic power supply system).
These units must be installed in parallel on the dc networks to be protected and provide common and different modes protection. Its installed location are recommended at both ends of the dc power supply line (solar panel side and inverter/converter side), especially if the line routing is external and long.
DC Fuse mainly used in DC combiner box in solar PV systems. When PV panel or inverter causes overload or short circuit, it trip off immediately, to protect PV panels. DC fuse also used to protect other electrical parts in DC circuit, when overload or short circuit.
photovoltaic dc isolator is mainly used solar power distribution system,direct current electrical equipment. Rated voltage 1200 VDC, rated current 32 A,science of arcing design solar photovoltaic power generation system reliable operation.
FMC4H Solar Fuse Connector A range of 10x38mm fuse links specifically designed for protecting photovoltaic strings. These fuse links are capable of interrupting low overcurrents associated with faulted photovoltaic string arrays (reverse current, multi-array fault).
1. The fuse/diode series connectors.
2. Low power loss.
3. Auto-lock equipment of male and female points enable connection more easy and reliable.
4. With the capacity of anti-aging and resistance to ultraviolet radiation on the outer cover.
5. Popular figure suit most of field installation.
6. Simple on-site processing.
7. With convenient installation,strong commonality.
