H25030-1S FUSE HOLDER BUSSMANN
H25030-1S FUSE HOLDER BUSSMANN – 1-Pole 30A 250V Class H Open-Style Fuse Block
The H25030-1S FUSE HOLDER BUSSMANN (Model H25030-1S) is a heavy-duty, single-pole open-style fuse block manufactured by Eaton’s Bussmann series. Designed specifically for Class H, K5, and R cartridge fuses (up to 30 Amps at 250 VAC/VDC), this open-style power distribution fuse holder provides safe, secure circuit protection across industrial power controls, HVAC equipment, and machinery panelboards.
Built with screw terminals and reinforced fuse clips, the H25030-1S FUSE HOLDER BUSSMANN accepts 18 to 10 AWGÂ copper wiring for easy installation and reliable electrical contact. Its flame-retardant thermoplastic construction offers superior heat dissipation and high insulation strength, while its compact chassis-mount design allows for straightforward backpanel mounting in crowded electrical enclosures.
As shown in the image, the fuse holder features a black thermoplastic chassis with bright yellow safety warning labels marked “BUSS UL LISTED CSA FUSEHOLDER” and “WITHSTAND RATING USE CLASS H FUSE”, along with heavy-gauge nickel-plated clip terminals equipped with combination screw connectors.
Key Features of the H25030-1S FUSE HOLDER BUSSMANN
-
Class H & K5 Fuse Compatibility: Engineered to hold standard 2” L x 0.56” Dia (14.3mm x 50.8mm) Class H or Class K5 250 V non-rejection fuses (such as Bussmann NON and REN series).
-
High-Clamping Screw Terminals: Equipped with sturdy screw connectors that secure 18 to 10 AWGÂ copper wire directly into reinforced clip terminals.
-
Reinforced Fuse Clips: Features spring-reinforced metal fuse clips that maintain constant contact pressure, minimizing voltage drop and preventing overheating from loose fitting fuses.
-
Thermoplastic Body Construction: Molded from high-grade, UL 94V-0 flame-retardant thermoplastic for high thermal stability and impact resistance.
-
Compact Open-Face Mounting: Open-frame chassis design facilitates easy visual inspection and quick fuse replacement without removing safety covers.
-
10kAÂ Interrupting Rating (SCCR): Rated for short-circuit withstand ratings up to 10kA RMSÂ Symmetrical at 250VAC.
Common Applications and Practical Usage
The rugged electrical design of the H25030-1S FUSE HOLDER BUSSMANN makes it a trusted component across commercial and industrial control applications:
-
Industrial Control Panels (ICPs): Provides primary and secondary power branch protection for industrial machinery and control enclosures.
-
HVAC Systems & Refrigeration: Widely installed in commercial HVAC control units, compressor circuits, and fan motor supply feeds.
-
Power Distribution Boards: Functions as an accessible single-pole branch fuse carrier within low-voltage AC/DC power distribution modules.
-
General Machinery Circuit Protection: Used in industrial ovens, pump controllers, and lighting power feeds requiring up to 30AÂ at 250VÂ overcurrent protection.

Operating Guidelines and Usage Tips
SAFETY NOTICE: Always disconnect main power and test with a calibrated voltage meter before replacing fuses or servicing terminal connections.
Wire Termination: Strip conductor ends to recommended lengths and torque terminal screws firmly to maintain low contact resistance.
Fuse Selection: Ensure the inserted cartridge fuse matches the 250VÂ voltage rating and does not exceed the 30AÂ maximum rating of the holder body.
To review official Class H power fuse block standards and industrial electrical safety codes, consult the National Electrical Manufacturers Association (NEMA) Directory.
