DNT2-R1N Semiconductor Fuse Overview
The GRL DNT2-R1N Semiconductor Fuse is a next-generation Ultra-Rapid Fuse Link engineered by GRL Fuse to protect the most valuable and sensitive components in high-power conversion systems. Designed specifically for circuits up to 1300V AC Fuse, the DNT2-R1N sets a new benchmark in High Voltage Fuse performance. As a true aR Fuse, it provides instantaneous Short-Circuit Protection, which is non-negotiable for modern Power Electronics like high-current IGBTs and Thyristors. Its defining feature is the Extremely Low I2t Value, ensuring that fault energy is limited to prevent thermal damage, guaranteeing superior System Reliability and extending component life.
DNT2-R1N Semiconductor Fuse Features
The DNT2-R1N’s unique construction is the key to its Ultra-Rapid performance:
- Optimized Fuse Element Design: Utilizes precision-punched pure silver elements embedded in high-density quartz sand. This maximizes the speed of melting and arc-extinction, making it a true Fast Acting Fuse.
- Superior Current Limiting Fuse Action: During a fault, the fuse melts so quickly that it generates a high arc voltage, which works to oppose the system voltage, rapidly forcing the current to zero. This active Current Limiting Fuse action protects the downstream devices.
- aR Characteristic: The fuse is calibrated to respond only to short-circuit faults, optimizing its speed for Power Semiconductor Protection. (FAQ Integration: Why is the DNT2-R1N an aR fuse? Because semiconductors have minimal tolerance for surge currents, they require the fastest possible Circuit Protection. The ‘aR’ characteristic ensures the fuse is optimized for this task, sacrificing overload protection for maximum short-circuit speed.)

DNT2-R1N Semiconductor Fuse FAQs
Q1: Is the GRL DNT2-R1N interchangeable with my current 690V fuses?
A: No. The DNT2-R1N is a 1300V AC Fuse designed for much higher system voltages. Using a lower-voltage fuse in a 1300V AC system is unsafe and will result in fuse failure and equipment damage. Always ensure the fuse voltage rating matches or exceeds the system voltage.
Q2: Does the Low I2t Value affect normal operation?
A: No. The Low I2t Value is a measure of the energy let-through during a fault. In normal operation, the fuse has a negligible power loss, and its robust design ensures long service life without nuisance tripping.
