Lovato GLX420315 IEC/EN fourth pole add-on 315A

Why Choose the GLX420315?

The Lovato GLX420315 fourth pole add-on accessory extends GL0160…GL0315 switch disconnectors with simultaneous pole operation. Designed for AC systems, this single-pole module closes in step with the main disconnector poles to support four-pole isolation where required. Built to Lovato’s GLX42 designation, the GLX420315 integrates cleanly with GL0160C1…GL0315C1 versions for consistent performance in industrial panels and distribution assemblies.

Rated Ith 315 A with Ui 1000 V and Uimp 12 kV, this accessory supports AC21A and AC22A duties at 315 A across 400, 500 and 690 V, and AC23A duties at 315 A (400 V) or 250 A (500/690 V). Conforming to IEC/EN 60947-3 and 60947-1, it delivers dependable four-pole switching capability for demanding AC applications in panelboards, switchboards and control assemblies.
