MEGA Bolt-on Fuse FAQ
1.What is MEGA Bolt-on Fuse?
MEGA Bolt-on Fuse is a high-current bolt-fixed overcurrent protection component. It is installed by bolt tightening, with rated current ranging from 60A to 650A. Specially designed for high-power and high-current circuits, it has high breaking capacity to ensure the safety of circuit equipment.
2.What scenarios are MEGA Bolt-on Fuses suitable for?
Widely used in high-current DC circuit protection scenarios such as automobile batteries, generators, new energy vehicles, trucks and buses, construction machinery, photovoltaic energy storage systems, industrial high-power power supplies, and ship circuits.
3.What are the core parameters of MEGA Bolt-on Fuse?
Rated current 60A-650A, rated voltage mostly 32VDC/120VDC, breaking capacity 2000A-2500A, operating temperature -40℃~125℃, terminals are tinned/silver-plated copper alloy, shell is high flame retardant material, compliant with RoHS standard.
4.What is the difference between MEGA Bolt-on Fuse and ordinary fuse?
MEGA Bolt-on Fuse is special for high current, installed by bolt fastening, with strong current carrying capacity and high breaking capacity, suitable for high-power circuits; ordinary fuses are mostly small-current and plug-in type, which cannot meet the protection needs of high-current circuits.
5.How to select MEGA Bolt-on Fuse?
Match the rated current of the circuit and select the corresponding specification fuse; 2. Confirm the rated voltage of the circuit and match 32VDC/120VDC; 3. Meet the circuit breaking capacity requirements; 4. Adapt to the corresponding MEGA bolt-on fuse holder to ensure the installation size fits.
6.What are the precautions for installing MEGA Bolt-on Fuse?
Tighten bolts moderately to prevent slipping or loosening; keep wiring terminals clean to avoid poor contact and heating; mixed use of different current and voltage specifications is strictly prohibited; keep the installation environment dry to avoid moisture short circuit.
7.What are the reasons for frequent blowing of MEGA Bolt-on Fuse?
Circuit overload and short circuit fault; equipment power exceeding the standard; small fuse specification selection; poor wiring contact leading to excessive temperature rise; internal component failure of equipment causing abnormal current.
8.How to deal with blown MEGA Bolt-on Fuse?
First check the root causes such as circuit short circuit and equipment failure. After eliminating the faults, replace the MEGA Bolt-on Fuse with the same model, current and voltage. It is forbidden to replace it with a higher current specification to avoid losing protection.
9.What safety certifications does MEGA Bolt-on Fuse have?
Mainstream certifications include UL, RoHS, CE, REACH. Some products adapt to automotive and marine certification standards, meeting the safety access requirements of domestic and foreign automotive, industrial and new energy markets.
10.Does MEGA Bolt-on Fuse support customization?
Customization of rated current, rated voltage, terminal specifications and installation holes is supported. Appearance color and logo can be customized, and exclusive certifications can be handled as required to meet the personalized customization needs of different high-current circuits.
