BEP Class T Fuse Holder with Two Studs (778-T2S-400-B)
This BEP Class T fuse holder pairs a fuse block with two cable connect studs in one compact unit, so the incoming and outgoing cables terminate directly on the holder. The fuse mounting studs suit the 400 and 600 series Class T fuses, all threads are metric, and the holder's common interconnection height lets it cluster with other products in the BEP Pro Installer range.

Parts Desk Insights
- Best use case: Main-circuit Class T fusing on a battery bank, where the two cable connect studs let the incoming and outgoing cables terminate directly on the holder.
- Most common customer mistake: Ordering a Class T fuse with the wrong stud series. The fuse mounting studs suit the 400 series (10 mm / 3/8") and 600 series (12 mm / 0.47") sizes, and the two series are not interchangeable.
- Sizing and fitment guidance: Plan for the 5.8" x 1.9" x 2.4" body and check the mounting space before ordering, confirm all threads are metric when choosing hardware, and match the Class T fuse rating to the circuit's continuous current.
