No. PKYS technical notes explain that Class-T fuses come in different distinct physical sizes based on their amperage. The different sizes require different fuse holders. At PKYS we stock three sizes. In addition there are other sizes and form factors available elsewhere.:
- Small (110A – 200A): Fits the Blue Sea 5007100 or Egis 3911 blocks.
- Mid (225A – 400A): Requires mid-sized blocks like the Blue Sea 5502, BEP 778-T2S-400 Pro Installer, or Egis 3912
- Large (450A – 600A): Requires large-format blocks like the Egis 3913 or BEP 778-T2S-600 Pro Installer series.
