Bussmann S506-5-R Low-Breaking Capacity Time-Delay Fuse

Bussmann S506-5-R Low-Breaking Capacity Time-Delay Fuse

The Bussmann S506-5-R is a time-delay, low-breaking capacity fuse engineered to deliver dependable overcurrent protection for electrical circuits and equipment. Its time-delay characteristic allows the fuse to ride through brief, harmless current surges — such as motor inrush, transformer energization, or switching transients — without nuisance opening, while still responding promptly to sustained overload or fault conditions. As a low-breaking capacity fuse, the S506-5-R is designed for use in circuits where available fault current remains within its interrupting rating, making it well suited to control circuits, instrumentation loops, and other lower-energy protection points. Specified as a direct replacement or for new installation, the Bussmann S506-5-R helps electrical professionals maintain consistent, code-conscious circuit protection across panels, control cabinets, and equipment enclosures.

Key Features

• Model S506-5-R: A Bussmann fuse identified by this specific catalog number, intended for straightforward cross-reference and replacement in compatible fuse holders and equipment.
• Time-Delay Response: Tolerates momentary current surges and inrush conditions common to motors, transformers, and capacitive loads, reducing nuisance fuse operation during normal startup events.
• Low-Breaking Capacity: Built for circuits where prospective fault current stays within the fuse's interrupting rating, a characteristic common to control, signal, and lower-energy circuit protection.
• Overcurrent Protection: Opens the circuit reliably under sustained overload or fault conditions to help protect downstream conductors, components, and connected equipment.
• Fuse-Holder Compatible: Sized and configured for installation in standard fuse holders and fuse blocks designed to accept this fuse style and catalog number.
• Bussmann Reliability: Manufactured under the Bussmann brand, a long-standing name in circuit protection products used across commercial, industrial, and OEM electrical applications.

Why Bussmann?

Bussmann has long been a trusted name in circuit protection, and the S506-5-R reflects that reputation through its time-delay, low-breaking capacity design intended for dependable, repeatable performance. Selecting a Bussmann fuse for replacement or new installation helps maintain consistent protection characteristics across an electrical system rather than introducing an unknown cross-reference part. For contractors, maintenance teams, and OEM builders, that consistency translates into fuse protection specified and stocked with confidence.
