MEGA® 70V High Performance SF51 automotive fuses employ diffusion pill technology to provide predictable time-delayed circuit protection. These MEGA fuses are ideal for protecting batteries, alternators, and heavy gauge wire harnesses that experience large inrushes of current. Use fuses with ampere ratings between 350 A and 500 A only for short circuit protection.
- Available with ampere ratings of 60 A to 500 A
- Interrupting rating of 2.5 kA at 70 V dc
- >1 MΩ open state resistance
- Operate at up to 125 °C
- Tin-plated copper alloy terminals
- PPA-GF33 housings with UL flammability ratings of HB
- M6 (9 Nm 1 Nm) and M8 (20 Nm 1 Nm) mounting holes
- Comply with ISO 20934 – Type SF51
- RoHS compliant
- High-contrast, color-coded ampere rating stamps on housings aid identification
- Available with two, one, or no mounting holes
- 51 mm pitch prevents mistaken replacement with other types of high-current fuses
