Siemens 3NE3-225 SITOR Fuse Link With Slotted Blade Contacts

Siemens 3NE3-225 SITOR fuse link with slotted blade contacts is a high‑current NH1 protection device for low‑voltage switchgear, part of the SITOR/SENTRON family, designed to interrupt short circuits or overloads in systems up to 1000 V AC. It features slotted blade contacts for M10 screw fixing and a mounting footprint of 110 mm, intended for direct installation in LV HRC fuse bases or switch disconnectors, with a front indicator available on some variants. Within the 3NE3 series, nominal current ratings vary by model, with examples including 200 A and 250 A versions while maintaining the 1000 V AC rating; this flexibility supports protection for a range of power electronics, motor drives, and distribution networks. The 3NE3-225 configuration aligns with the NH1 footprint and aims for straightforward replacement in existing Siemens installations, delivering robust blade connectivity and a compact 110 mm mounting profile that supports reliable performance and easy maintenance.
