NON -60 CLASS K5 FUSE BUSSMANN
NON -60 CLASS K5 FUSE BUSSMANN – Industrial 60A 250VAC/125VDC General-Purpose One-Time Fuse
The NON -60 CLASS K5 FUSE BUSSMANN (Model NON-60) is an industrial-grade, general-purpose non-time-delay power fuse manufactured by Eaton’s Bussmann series. Engineered specifically to provide basic overcurrent and short-circuit protection for lighting systems, heating circuits, non-inductive loads, and general electrical branch circuits, this 60-amp, 250 VAC / 125 VDC fuse delivers reliable circuit protection across commercial and industrial distribution panels.
Featuring a fast-acting one-time response profile, the NON -60 CLASS K5 FUSE BUSSMANN opens quickly under short-circuit and continuous thermal overload conditions to safeguard connected equipment and conductors. It provides an interrupting rating of 50 kA RMS Symmetrical at 250 VAC and 50 kA at 125 VDC. Constructed in a standard UL Class K5 ferrule body format (13/16”x 3”), this fuse fits into standard 250V Class H and Class K fuse blocks and safety switches.
Key Features of the NON -60 CLASS K5 FUSE BUSSMANN
-
Basic General-Purpose Protection: Designed for non-inductive loads where high motor-inrush current withstand is not required, providing economical overcurrent protection.
-
Dual Voltage Operation: Rated for continuous service at 250 VAC and 125 VDC, making it suitable for both AC distribution and DC auxiliary networks.
-
50kA Interrupting Rating: Safely interrupts available fault currents up to 50 kA RMS Symmetrical at 250 VAC and 50 kA at 125 VDC.
-
Standard Ferrule Dimensions: Standardized 13/16 inch x 3 inch (20.6 x 76.2 mm) body dimensions ensure broad compatibility across standard 250V fuse clips.
-
Economical One-Time Design: Provides a cost-effective solution for main panel feeds, lighting disconnects, and resistance-heating circuits.
-
Durable Construction: Built with high-strength composite tube housing capped with heavy-duty copper/brass ferrule ends for optimal conductivity.
Common Applications and Practical Usage
The straightforward fast-acting response, 60 A rating, and physical ferrule footprint of the NON -60 CLASS K5 FUSE BUSSMANN make it widely used across general industrial installations:
-
Commercial & Industrial Lighting: Protects branch circuits supplying high-density fluorescent, LED, and incandescent lighting panels.
-
Electric Resistance Heating: Safeguards electric duct heaters, baseboard heaters, and industrial process heating elements.
-
General Distribution Panelboards: Provides primary or secondary overcurrent protection in general 250V switchboards, panelboards, and disconnect switches.
-
Non-Inductive Electrical Loads: Ideal for resistive loads where high startup inrush currents are absent.

Operating Guidelines and Usage Tips
SAFETY NOTICE: Always isolate main power sources and verify circuits are fully de-energized using a calibrated voltage tester prior to inspecting or replacing power fuses.
Holder Compatibility: Install in standard 250V ferrule fuse blocks or safety disconnect switches (such as Bussmann H250 series holders).
Application Caution: For motor branch circuits or inductive transformer loads with high inrush currents, consider using time-delay fuses (such as Bussmann Fusetron FRN-R series) to avoid nuisance opening during startup.
To review official low-voltage fuse standards and Class K5 protection requirements, consult the National Electrical Manufacturers Association (NEMA) Directory.
