We specialize in providing authentic, durable, and highly reliable replacement fuses designed to meet the rigorous specifications of top-tier CNC brands like Fanuc™, Yaskawa, and Mitsubishi. If you are experiencing drive alarms, dead control panels, or power supply failures, replacing a blown fuse with the correct HP Series component is often the fastest and most cost-effective solution.
Browse our extensive inventory to find the exact replacement HP part you need, check live prices, and secure fast global shipping to get your workshop back up and running immediately.
Understanding the Role of HP Series Fuses in CNC Systems
The HP Series, predominantly manufactured by trusted brands like Daito, is a specific class of alarm-indicating fuses widely used in Japanese CNC machinery. These fuses are not your standard off-the-shelf glass tubes; they are highly specialized safety devices engineered for precision. They provide instantaneous short-circuit and overcurrent protection, safeguarding sensitive printed circuit boards (PCBs) and internal drive circuitry.
Why OEM Quality Matters
Technical buyers and maintenance engineers know that compromising on circuit protection can lead to catastrophic hardware failure. A cheap aftermarket fuse might not blow at the rated current, potentially destroying a high-value Fanuc™ Power Supply or an expensive Fanuc Drive. Genuine HP Series fuses are designed to interrupt the current flow within milliseconds of a fault, adhering to exact tolerance levels. In electrical terms, protecting your circuit dictates that the fuse rating should safely accommodate the load, generally operating under the safety margin formula $I_{fuse} \ge I_{load} \times 1.25$, while reacting instantly to dangerous spikes.
Selection Guide: How to Identify the Correct HP Series Fuse
Choosing the correct replacement CNC fuse requires matching several critical parameters. Here is a step-by-step guide for procurement officers and workshop technicians to ensure perfect compatibility:
- Check the Amperage Rating (A): The most crucial specification. HP fuses range from small fractional amp ratings (e.g., 0.32A, 0.5A) up to larger ratings like 5A or 10A (e.g., HP32, HP50). This rating is usually stamped directly on the top or side of the fuse body.
- Verify the Voltage (V): Standard HP Series fuses are typically rated for 250V AC/DC. Ensure this matches the circuit you are protecting, whether it is a low-voltage I/O board or a high-voltage servo amplifier circuit.
- Identify the Fanuc Part Number: If you are working on a Fanuc CNC system, the fuse will often correspond to a specific Fanuc part number format, such as
A60L-0001-xxxx. Cross-referencing this number guarantees perfect fitment. - Physical Dimensions & Mounting: HP Series fuses feature specific pin spacings. Confirm whether your board requires plug-in pins or if it mounts into a specific fuse holder base.
Pro Tip: If your fuse blows repeatedly upon machine startup, do not just replace the fuse. Check downstream components for short circuits, particularly inspecting the CNC Cables and the Fanuc Servo Motors for grounding issues.
CNC Fuse Series Comparison: HP vs. LM, MP, and HM
While the HP series is ubiquitous, CNC machines utilize various fuse footprints depending on the generation and specific application module. Use the technical comparison table below to distinguish the HP Series from other common fuse types available in our CNC Fuses Category.
| Fuse Series | Typical Voltage Rating | Primary Application | Alarm Function | Direct Link |
|---|---|---|---|---|
| HP Series | 250V AC/DC | Power supplies, servo amplifiers, main PCBs | Yes (White flag/pin indicator) | View HP Fuses |
| LM Series | 48V / 125V | Low voltage logic boards, I/O modules | Yes (Clear window indicator) | View LM Fuses |
| MP Series | 125V AC/DC | High-density PCBs, compact controllers | Yes | View MP Fuses |
| HM Series | 250V AC/DC | Heavy-duty motor protection circuits | Yes (Heavy duty pin) | View HM Fuses |
