The GOULD SHAWMUT A4BT800 (now Mersen / Ferraz Shawmut) is an Amp-Trap® 800A Class L time-delay, current-limiting fuse designed for mains, feeders, transformers and other high-inrush electrical applications. This listing features reclaimed, continuity-tested units removed from decommissioned operational equipment.
Time-Delay, Current-Limiting: Designed to accommodate temporary motor and transformer inrush while providing current-limiting overcurrent protection.
800A Class L Construction: Heavy-duty Class L fuse construction for high-current industrial power-distribution applications.
High Interrupting Capacity: Rated for high available fault-current environments when installed within its specified voltage and application limits.
Class L Blade Configuration: Designed for compatible Class L fuse mounting hardware. Verify dimensions and mounting arrangement against the original equipment before ordering.
Reclaimed & Verified: Each unit is continuity-tested and visually inspected prior to sale; contact Gruber regarding new Mersen stock availability.

| A4BT800 | UPS equipment, mains, feeders, transformers, distribution systems and other high-current equipment specifically designed for an 800A Class L time-delay fuse or an OEM-approved equivalent. | Verify the OEM part number, 800A rating, circuit voltage, Class L mounting arrangement, physical dimensions and required interrupting rating before ordering. |
Important: Confirm the original equipment fuse specification, voltage, current rating, interrupting rating, mounting configuration and physical dimensions before installation. Do not substitute a fuse solely because its amperage and voltage ratings appear similar.
