Siemens SITOR Fuse-Link 3NE1802-0 (SI-FL-SITOR-40A-690VAC)
₦73,745.10
The Siemens 3NE1802-0 is a SITOR NH000 semiconductor fuse-link rated at 40A and 690VAC.
Designed with gS characteristics, it provides ultra-fast protection for sensitive power electronics.
Ideal for safeguarding converters, drives, and semiconductor devices in industrial systems.
The Siemens 3NE1802-0 SITOR fuse-link is specifically engineered for the protection of semiconductor devices and power electronic equipment. With a rated current of 40A and voltage rating of 690VAC, this NH000 size fuse provides fast-acting gS protection, ensuring rapid disconnection during fault conditions to prevent damage to sensitive components such as thyristors, diodes, and IGBTs.
SITOR fuse-links are optimized for low let-through energy (I²t), making them highly effective in minimizing thermal and mechanical stress on protected devices. The NH000 form factor ensures compatibility with standard fuse bases and switch-disconnectors used in industrial power distribution systems.
Designed for high-performance industrial environments, the 3NE1802-0 offers reliable operation, precise protection characteristics, and long service life, making it a critical component in modern power electronics and automation systems.
