ZCASE® Bolt-Down Fuses: Compact, High-Current Protection up to 250A

The single ZCASE® fuse is a compact, bolt-down fuse designed for high-current protection up to 250A, offering a minimal footprint ideal for tight spaces. With a time-current characteristic similar to the Mega fuse, the ZCASE® provides full wire protection and can be mounted directly to a battery post or bus bar using a single M6 bolt. Its robust design makes it suitable for various heavy-duty applications.

Constructed with a PPA (33% GF) cover and base, a ceramic insulating tube, and tin-plated copper terminals, the ZCASE® fuse ensures durability and reliable performance. Rated for 32V DC, it has an interrupting capacity of 2000A at 32V DC and operates within a wide temperature range of -40°C to 125°C. The fuse requires a mounting torque of 9.8Nm ± 1.4Nm for secure installation.
