Cooper Bussmann 1BS101 Fuse Block

1BS101 is a Cooper Bussmann (now Eaton Bussmann) one-pole fuse block designed for bolt-down, stud-mounted installation. It is rated for up to 600 V and 100 A and is intended to hold standard 5 x 30 mm fuses, making it a compact, modular protection base for single-circuit applications. The block uses a plated-steel fuse mounting stud and tin-plated wire termination connectors to aid secure mounting and heat dissipation within panels, cabinets, or equipment enclosures. As part of the Bussmann 1BS10x universal fuse block family, the 1BS101 provides a straightforward, replaceable protection point for power distribution and control circuits that require quick fuse changes and clear circuit protection up to the 600 V class. This configuration supports reliable, centralized protection in industrial environments where a single fuse safeguards a specific branch, drive, or accessory circuit, simplifying wiring layouts and maintenance while preserving standard fuse sizes for availability and interchangeability.
