GE0161NT4 - 4P SWITCH DISCONNECTOR W/NH FUSE HOLDER

Why Choose the GE0161NT4?

Lovato GE0161NT4 is a four‑pole switch disconnector with NH fuse holder designed for dependable AC isolation and protection. Rated Ith 160 A with Ui 800 V and Uimp 8 kV, it supports AC21A/AC22A duty up to 690 V. Robust IP20 frontal protection and 100 kA conditional short‑circuit withstand make it ideal for industrial switchgear and panel applications.

Engineered for durability, the GE0161NT4 offers 10,000 mechanical cycles, secure terminals up to 13 Nm torque, and reliable operation from −25 to 55 °C at altitudes to 3000 m. Simple screw‑on plate installation and compliance with IEC/EN 60947‑1 and 60947‑3 streamline specification for OEMs and MROs seeking consistent AC23A performance, including 125 A at 690 V.
