GE0630NT4 - 4P SWITCH DISCONNECTOR W/NH FUSE HOLDER

Why Choose the GE0630NT4?

Lovato’s GE0630NT4 is a robust four‑pole switch disconnector with NH fuse holder for AC applications up to 630 A. It offers a rated insulation voltage Ui of 1000 V and a 12 kV impulse withstand, with 100 kA conditional short‑circuit capability. IP20 frontal protection and compliance with IEC/EN 60947‑1 and 60947‑3 make it a dependable choice for panel builders.

Consistent 630 A AC21A and AC22A ratings at 400, 500 and 690 V, plus 400 A AC23A at 690 V, support demanding load switching. Screw‑on plate installation, a 5000‑cycle mechanical life, and -25 to 55 °C operating range simplify integration and maintenance. NH fuse technology and four‑pole isolation enhance safety in industrial and commercial distribution panels.
