Core Features & Advantages
-
Premium Ceramic Housing
The fuse body is made of high-temperature resistant ceramic material, featuring excellent insulation, heat dissipation and flame retardant performance. It can adapt to harsh automotive working environments (-40℃ to 125℃), avoid deformation, aging and damage caused by high temperature or vibration, and extend the service life of the fuse.
-
Stable Bolt-Down Installation
Designed with standard bolt-down mounting structure (M6/M8 bolt optional), it realizes firm and stable fixed installation, effectively preventing loose contact and poor circuit connection caused by vehicle vibration. It is easy to install and replace, suitable for various automotive modification and maintenance scenarios.
-
High Current Protection Performance
Complying with automotive fuse industry standards, the ANL/B30BSF51 mega fuse has a wide current rating range (60A-500A) and high breaking capacity, which can quickly cut off the circuit in case of current overload or short circuit, protecting automotive electrical equipment and circuits from damage, and ensuring driving safety.
-
Standardized Specification Compatibility
Fully compatible with ANL and B30BSF51 fuse standards, with 51mm standard pitch to avoid wrong replacement with other types of high-current fuses. The color-coded ampere rating design enables quick identification of current specifications, improving installation and maintenance efficiency.
