Mersen B219191 D01 gR high-speed semiconductor fuse link rated 6 A, 440 V AC/DC with a 100 kA breaking capacity for protecting power electronic equipment.
The Mersen B219191 is a high-performance D01 gR high-speed Neozed fuse link designed to provide rapid protection for sensitive semiconductor devices and power electronic equipment. As part of the trusted Mersen RECTICUR® D0 high-speed fuse range, it delivers exceptional fault-clearing performance to help minimise damage caused by short circuits in industrial electronic systems.
Rated at 6 A with operating voltages up to 440 V AC and 440 V DC, the B219191 is specifically engineered for semiconductor protection applications where extremely fast fault interruption is essential. Its compact D01 Neozed format allows simple installation into compatible D0 fuse bases whilst maintaining high breaking performance.
Manufactured using a ceramic body with precision-engineered fuse elements, the fuse offers a 100 kA AC breaking capacity, low power dissipation and excellent current-limiting characteristics, making it ideal for protecting drives, converters, UPS systems and other power electronics.
Unlike general-purpose fuse links, gR semiconductor fuses are designed to respond extremely quickly to high fault currents, helping protect costly semiconductor devices such as IGBTs, thyristors, rectifiers and power modules before thermal damage can occur.
The Mersen B219191 combines high interrupting capacity with precise current-limiting characteristics, making it suitable for modern industrial automation, renewable energy equipment and power conversion systems requiring reliable semiconductor protection.
