Tea Melting Ceramic Fuse Tubes (Models R054, R055, R057, R058)
Overview
Our 6×30mm MRO ceramic fuse tubes offer a critical safety solution for overcurrent and short-circuit protection in medium-to-high voltage with key industry standards, these fuses ensure reliable circuit interruption within ceramic bodies engineered for thermal stability at 500V rated voltage.
Key Specifications
- Dimensions: 6×30mm (Industry-standard miniature tube size)
- Voltage Rating: 500V AC
-A15A, 4A, 5A, 6A, 6.3A, 8A, 10A, 12A, 15A, 16A, 20A, 25A, 30A
- Series: R054/R055 (High-speed), R057/R058 (Time-lag options)
- Performance Advantages
① Enhanced Safety Features
The ceramic housing provides superior mechanical strength compared to glass fuses, maintaining integrity under repeated electrical stress. The sand filler optimizes arc extinction performance at 500V, even at high fault currents.
② Thermal Endurance
These fuses operate flaw ranging from -55°C to +125°C thanks to precise alloy calibration within the Tea™ (Time Electrically Adaptive) melting design.
③ Application Versatility
With 18 standardized current ratings spanning 0.25A–30A, these units cover needs across:
- Industrial control circuits
- Power supply units
- Telecommunications equipment
- Automotive electronics (compliant with IEC 60127-2-1)
Compliance & Reliability
R-series certification ensures adherence to short-circuit testing endurance protocols through accelerated life testing.
Recommended Use Case
For circuits requiring:
✔️ Consistent 500V protection in crowded PCB real estate
✔️ Fast-acting protection for sensitive ICs (R054/R055)
Ordering Note: Specify required model + current rating code (e.g., R058-30A). Bulk packaging with ESD protection ensures intact delivery. Factory-tested traceability protocols included.
