BEP 778-T2S-600-B Pro Installer Class T Fuse Holder 450A-600A

BEP Pro Installer Class T Fuse Holder with Dual Power Studs (450A–600A)

The BEP 778-T2S-600-B is an ultra-heavy-duty Class T fuse holder engineered for high-capacity battery bank, inverter/charger, and main bow thruster DC branch protection. Designed to accommodate 450A to 600A Class T fuses, this model includes two integrated M10 (3/8") auxiliary power studs directly on the load side, enabling direct connection of secondary distribution leads or sensor cables without requiring external terminal posts or busbars.

Featuring extreme current interrupt capabilities (20,000A AIC @ 160V DC), Class T fuses are mandatory for high-energy Lithium (LiFePO₄) battery systems and large inverter installations where fast-acting protection against short-circuit faults is required. Built on BEP’s modular Pro Installer footprint (MC10 cluster standard), the holder features tinned CDA 110 copper busbars, high-temperature glass-filled nylon construction, and a snap-on insulating cover with break-out sides for clean multi-directional cable entry.

Key Features

• High Interrupt Capacity (AIC): Designed specifically for Class T fuses that safely clear short-circuit faults up to 20,000A without explosive arcing.

• Integrated Dual Auxiliary Power Studs: Features two extra M10 (3/8") studs to combine power feeds, sense wires, or accessory connections directly at the fuse block.

• Pro Installer Modular Architecture: Interlocks cleanly with other Pro Installer busbars and switches to optimize panel space and reduce installation time.

• High-Conductivity Tin-Plated Copper: Utilizes CDA 110 copper busbars with electro-tin plating to minimize electrical resistance and resist salt-spray corrosion.

• Clear Insulating Cover: Flame-retardant clear polycarbonate cover shields live high-amperage components to meet ABYC/USCG safety standards.
