Bussmann S506 Series Low-Breaking Capacity Time-Delay Fuse

Bussmann S506 Series Low-Breaking Capacity Time-Delay Fuse

The Bussmann S506 Series covers time-delay, low-breaking capacity fuses engineered to deliver dependable overcurrent protection for electrical circuits and equipment, available in models S506-5-R and S506-10-R. Each fuse in the series shares a common ferrule end x ferrule end connection style, a European (IEC) construction standard, a 35 ampere interrupt rating, and a 50 hertz frequency rating, with a non-indicating body style. 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 Series is designed for use in circuits where available fault current remains within its 35 ampere interrupt 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 Series helps electrical professionals maintain consistent, code-conscious circuit protection across panels, control cabinets, and equipment enclosures.

Key Features

• S506 Series Models: Offered as S506-5-R and S506-10-R, allowing selection of the correct catalog number 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 35 ampere interrupt rating, a characteristic common to control, signal, and lower-energy circuit protection.
• Ferrule End X Ferrule End Connection: Sized and configured for installation in standard fuse holders and fuse blocks designed to accept this ferrule-style fuse.
• European (IEC) Construction: Built to IEC conventions, supporting use in equipment and panels specified to European electrical standards.
• 50 Hertz Frequency Rating: Matched to 50 hertz supply systems commonly found in IEC-standard installations.
• Non-Indicating Design: Standard non-indicating body for straightforward installation without a blown-fuse indicator.
• 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 Series 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 working with ferrule-style, IEC-standard, 35 ampere interrupt-rated fuses, that consistency translates into protection specified and stocked with confidence across the S506-5-R and S506-10-R models.
