Bussmann FRN-R-5-6/10 Fusetron Time-Delay Fuse

Bussmann FRN-R-5-6/10 Fusetron Time-Delay Fuse, 250V

The Bussmann FRN-R-5-6/10 is a Fusetron time-delay fuse built to deliver dependable overcurrent protection in 250V electrical systems. Its fractional 5-6/10 amp rating is designed for circuits and equipment that call for precise, low-current protection rather than a full whole-amp fuse size. As part of the Bussmann Fusetron family, the FRN-R-5-6/10 is engineered with time-delay characteristics that allow it to ride through brief, harmless current surges common in motor starting and inrush conditions, while still responding quickly to sustained overcurrent faults. Electrical contractors and maintenance professionals specify the FRN-R-5-6/10 by its exact model number to ensure a correct, code-compliant replacement in panelboards, control circuits, and distribution equipment.

Key Features

• Amperage Rating: Rated 5-6/10A, this fractional amperage rating provides precise overcurrent protection for low-current circuits, control transformers, and instrumentation that a standard whole-amp fuse cannot properly protect.
• Voltage Rating: Rated 250V, the FRN-R-5-6/10 is suited to standard low-voltage electrical distribution and branch-circuit applications.
• Fusetron Series Design: Manufactured as part of the Bussmann Fusetron line, this fuse is built for the dependable, repeatable performance the Fusetron name is known for in the field.
• Time-Delay Performance: The Fusetron design is engineered to tolerate momentary current surges, such as inrush current, while still opening promptly under sustained overcurrent conditions to protect connected equipment.
• Exact Model Match: Identified by the model number FRN-R-5-6/10, this fuse allows electricians and facility teams to cross-reference and order the correct replacement with confidence.
• Bussmann Manufacturing: Produced by Bussmann, a long-established manufacturer of fuses and overcurrent protection devices used throughout commercial, industrial, and residential electrical systems.
