Product Introduction
Low Voltage DC Fuse series is an overcurrent protection device specially designed for photovoltaic power generation, energy storage systems, DC distribution cabinets, new energy charging piles and other DC scenarios. The product adopts a ceramic shell structure, featuring high temperature resistance, arc resistance, fast breaking speed and high reliability. It can quickly cut off fault current when short circuit or overload occurs in the DC circuit, thereby protecting PV modules, combiner boxes, inverters and related electrical equipment.
Among them, Ceramic Low Voltage Fuse,1000v dc fuse is a common core protection component in photovoltaic DC systems. It is mainly used in key positions such as DC side confluence, string protection and inverter input protection, which can effectively reduce the risk of equipment burnout and fire caused by abnormal current. This Low Voltage DC Fuse is suitable for 1000V DC voltage level, with high breaking capacity and stable long-term performance, making it an essential safety protection component in photovoltaic systems.
This series covers multiple current ratings, such as 200A, 400A, 630A, etc., and can be selected according to different system power and protection requirements. The product adopts a square blade-type structure, which is easy to install and quick to replace, suitable for industrial batch installation and on-site maintenance.

FAQ
Q1: The product is rated for a breaking capacity of 50 kA. Under actual short-circuit conditions, can it reliably extinguish the arc, and are there any risks of shell breakdown?
A:The HMEVF10G series has a rated breaking capacity of 50kA at DC1000V. The shell is made of thickened high-temperature resistant industrial ceramics, and the interior is filled with high-purity quartz sand for layered arc extinguishing structure. Sampling of each batch undergoes extreme DC short-circuit breaking tests, which can cut off 50kA DC short-circuit current at one time without defects such as shell cracking, arc spraying out or ceramic body fracture. It fully complies with the mandatory standard EN/IEC60269-4 for PV DC fuses, eliminating quality risks of fire caused by short circuit.
Q2: Does this HMEVF10G series fuse generate heat and cause damage during long-term direct current current flow? How long is the product warranty?
A:This series adopts High Breaking Capacity Alumina Ceramic,there will be no overheating shell burning or premature fusing caused by melt aging.Every unit undergoes full inspection of DC voltage withstand and current aging before delivery.
