Core Features & Safety Advantages
YM fuses are engineered to provide predictable, reliable, and safe protection where it matters most.
Defining Product Features
- Calibrated & Predictable Operation: Each fuse undergoes precise calibration to ensure it operates within its specified time-current curve, providing consistent and predictable protection for sensitive Aircraft Electrical Systems.
- High Interrupting Rating: Designed to safely interrupt high-fault currents without explosive rupture, containing the arc and preventing damage to the surrounding Aviation Fuse Holder or panel.
- Environmental Resilience: Constructed to withstand vibration, shock, thermal cycling, and corrosive atmospheres common in aviation and military applications.
- Visual Fault Indication (Glass Types): Clear glass bodies allow for instant visual confirmation of a blown element, speeding up maintenance and troubleshooting.
- Low Contact Resistance: Precision-made end caps and elements ensure minimal voltage drop and heat generation under normal operating conditions, contributing to overall system efficiency.
The YM Advantage in Circuit Protection
- Complete System Solution: We supply not just the fuse, but also the compatible, high-quality Aviation Socket and holders (like the BZ-2), ensuring optimal electrical and mechanical performance.
- Military-Grade Reliability: Our military fuse lines (e.g., BHC series) are built to stringent specifications for durability and performance in the most demanding conditions.
- Rigorous Quality Assurance: 100% electrical testing verifies current rating and breaking capacity. Statistical process control ensures batch-to-batch consistency you can rely on.
How to Select & Safely Replace an Aviation Fuse: A Step-by-Step Guide
Correct selection and replacement are critical for maintaining system safety and protection.
- Identify the Fault & Isolate Power: Confirm a blown fuse via indicator or visual inspection. Before any action, completely isolate the circuit's power source following safety procedures.
- Select the Correct Replacement:
- Current Rating: Match the amperage marked on the old fuse exactly. Never substitute with a higher rating.
- Voltage Rating: Must be equal to or greater than the circuit voltage.
- Type & Speed: Match the physical size (e.g., 8x37, 6x30) and time-current characteristic (Fast or Slow-blow).
- Inspect the Fuse Holder: Visually inspect the aircraft fuse holder for signs of arcing, overheating, or corrosion. Clean contacts if necessary.
- Install the New Fuse: Insert the new fuse firmly into the clean holder, ensuring it is fully seated. For knob-type fuses, hand-tighten securely.
- Restore Power & Monitor: Restore power to the circuit. Monitor for normal operation. If the new fuse blows immediately, a deeper fault investigation is required—do not continue to replace fuses.
Critical Application Scenarios
YM fuses are the frontline defense in a wide array of aerospace and defense electrical systems.
- Avionics Bay & Instrumentation: Protecting sensitive navigation, communication, and flight control computers from overloads.
- Cockpit Control Panels: Safeguarding power to displays, lighting, and control interfaces.
- Primary & Secondary Power Distribution: Installed in power distribution units (PDUs) and remote power controllers to protect feeder and branch circuits.

Precision-Driven Production Process
Every YM fuse is the result of a meticulous, quality-focused manufacturing journey.
- Precision Element Fabrication: The fuse element (wire or strip) is formed from high-purity metal with exact dimensional and resistivity control.
- Automated Assembly: Elements are accurately positioned and welded to plated end caps within the glass or ceramic body in controlled, automated stations.
- Calibration & Filling: For sand-filled fuses, precise arc-quenching material is added. The assembly may undergo electrical calibration pulses.
- Sealing: The body is hermetically sealed to prevent moisture ingress and stabilize the internal environment.
- 100% Electrical & Visual Testing: Every single fuse undergoes hi-pot testing, resistance check, and in many cases, a calibrated pre-fusing test to verify its operational characteristics.
- Lot Sample Testing: Statistical samples from each production lot undergo destructive testing to validate time-current curves and interrupting capacity.
