NON-35 CLASS K5 FUSE BUSSMANN

NON-35 CLASS K5 FUSE BUSSMANN – Industrial 35A 250VAC/125VDC General-Purpose One-Time Fuse

The NON-35 CLASS K5 FUSE BUSSMANN (Model NON-35) is an industrial-grade, general-purpose non-time-delay power fuse manufactured by Eaton’s Bussmann series. Engineered specifically to deliver foundational overcurrent and short-circuit protection for lighting systems, heating circuits, non-inductive loads, and general electrical branch circuits, this $35text{-amp}$ , $250text{ VAC} / 125text{ VDC}$ fuse provides economical circuit protection across commercial and industrial distribution panels.

Featuring a fast-acting one-time response profile, the NON-35 CLASS K5 FUSE BUSSMANN clears quickly during short circuits and continuous thermal overloads to safeguard connected equipment, conductors, and switches. It offers an interrupting rating of $50text{ kA RMS}$ Symmetrical at $250text{ VAC}$ and $50text{ kA}$ at $125text{ VDC}$ . Built in a standard UL Class K5 ferrule body format ( $13/16'' times 3''$ ), this fuse fits seamlessly into standard 250V Class H and Class K fuse blocks, safety switches, and disconnect panels.

Key Features of the NON-35 CLASS K5 FUSE BUSSMANN

Basic General-Purpose Protection: Optimized for non-inductive electrical circuits where motor-starting inrush surges are absent, delivering reliable and economical protection.
Dual Voltage Operation: Fully rated for continuous operation at $250text{ VAC}$ and $125text{ VDC}$ , providing multi-system capability across AC power and auxiliary DC circuits.
50kA Interrupting Rating: Safely interrupts high prospective fault currents up to $50text{ kA RMS}$ Symmetrical at $250text{ VAC}$ and $50text{ kA}$ at $125text{ VDC}$ .
Standard Industrial Ferrule Body: Standardized $13/16text{ inch} times 3text{ inch}$ ( $20.6 times 76.2text{ mm}$ ) body dimensions ensure broad compatibility across standard 250V fuse clips.
Cost-Effective One-Time Design: Serves as a budget-friendly overcurrent solution for lighting panels, service disconnects, and resistance heating elements.
Durable Physical Construction: Constructed with a high-strength composite body fitted with heavy-duty end caps for maximum conductivity and mechanical strength.

Common Applications and Practical Usage

The straightforward fast-acting clearing speed, $35text{A}$ rating, and physical ferrule profile of the NON-35 CLASS K5 FUSE BUSSMANN make it widely used across general industrial and commercial installations:

Commercial & Industrial Lighting Panels: Safeguards main feeder and branch circuits feeding high-density fluorescent, LED, and incandescent lighting grids.
Resistance Heating Systems: Protects duct heaters, baseboard electric heaters, and industrial process heating elements from thermal overloads.
General Power Distribution: Provides primary or secondary branch protection in standard 250V panelboards, switchboards, and fused safety switches.
Non-Inductive Electrical Loads: Ideal for purely resistive or light commercial loads where startup surge currents are negligible.

Operating Guidelines and Usage Tips

SAFETY NOTICE: Always isolate main power supplies and verify circuits are completely de-energized with a calibrated voltage tester before inspecting or replacing power fuses.

Holder Compatibility: Mount 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 subject to heavy starting inrush, consider using dual-element time-delay fuses (such as Bussmann Fusetron FRN-R series) to avoid nuisance opening.

To review official low-voltage fuse standards and Class K5 protection requirements, consult the National Electrical Manufacturers Association (NEMA) Directory.
