DC Fuse mainly used in DC combiner box in solar PV systems. When PV panel or inverter caused 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. Solar photovoltaic DC fuse is an electronic device used for DC circuit protection in solar photovoltaic power generation systems. Its main function is to monitor and cut off the flow of abnormally high current in the photovoltaic power generation system to protect equipment such as photovoltaic modules, inverters and batteries from overcurrent damage. Solar photovoltaic DC fuses are usually installed in the DC circuit of photovoltaic power generation systems. When the current exceeds the rated current of the fuse, the fuse will quickly cut off the circuit to prevent further current from flowing. This protects critical components in the system from risks such as fire, short circuits, etc.High rated current and voltage capability: The solar photovoltaic DC fuse can withstand high current and voltage, and automatically cut off the circuit when the rated value is exceeded, effectively protecting the safety of the photovoltaic power generation system. Quick cut-off capability: When an abnormally high current occurs in the solar photovoltaic system, the DC fuse can quickly cut off the circuit, preventing the current from flowing to damaged equipment, and effectively avoiding fire and other safety problems. High temperature resistance performance: The material and design of solar photovoltaic DC fuses can withstand high temperature environments, ensuring long-term stable operation in hot summer or high temperature areas. Low power consumption: The solar photovoltaic DC fuse can maintain low power consumption during normal operation, and will not cause energy waste or affect the power generation efficiency of the system. High reliability: The design and manufacture of solar photovoltaic DC fuses strictly follow international standards, have good reliability, and can run stably for a long time, reducing failure and maintenance costs.Q 1: What's your DC MCB rated current range? A: We offer DC MCB from 1A to 125A, the FMB7N-63PV DC MCB is 1A~63A, the FMB1Z-125 DC MCB is 80A~125A. Q 2: How do you control quality? A: Firstly, all raw material we selected the high quality one. Secondly, our professional and skilful workers care every details in handling the producing. Thirdly, our quality control department specially responsible for quality checking in each process. Finally, our product strictly follow ISO9001 quality control system, all products must be tested after finished production. Q 3: What’s the difference between DC MCB and AC MCB? A: DC MCB function is the same as AC MCB. It’s difficult to interrupt and extinguish the arc in the DC circuit, so the configuration of the accessories of the same product is much higher than that of the AC model type. Q 4: About delivery time, how long should I wait before get my order? A: It depends on your purchase order. It's better we discuss according to your detail plan. Q 5: What's your payment term? A: We accept T/T, L/C, D/A, D/P, WESTERN UNION, PAYPAL, CASH. Q 6: Which countries you have exported to? A: We already ship to many African countries, Middle East, South America, Southeast Asia, etc. We are happy to see that with our professional services and solutions, our clients get more business and the end users are satisfied.
