Overview
The Siemens 3NE8022-1 SITOR fuse link is an essential component for modern industrial power systems. Engineered specifically for semiconductor protection (aR class), it provides significantly faster response times than standard power fuses. Its robust design with blade contacts makes it ideal for NH-type fuse bases, ensuring low power loss and high breaking capacity in both AC and DC applications.
Key Benefit
-
Ultra-Fast Response: Specifically tuned (aR characteristic) to protect sensitive power semiconductors from overcurrent and short circuits.
-
Dual Voltage Versatility: Rated for up to 690 V AC and 440 V DC, providing flexibility across different power architectures.
-
Visual Maintenance: Equipped with a front indicator for immediate visual identification of tripped fuses, reducing downtime.
-
Siemens Reliability: Built to high industrial standards, ensuring long-term stability and precise tripping curves.
Function & Features
-
Class aR Protection: Partial range protection for semiconductors (short-circuit protection only).
-
Blade Contacts: Standardized NH00 size for easy installation in industrial fuse holders.
-
High Breaking Capacity: Capable of safely interrupting high fault currents to prevent equipment damage.
-
Compact Design: The NH00 form factor allows for high-density mounting in control cabinets.
