Lovato GLX420500 IEC/EN fourth pole add-on 500A

Why Choose the GLX420500?

The Lovato GLX420500 Fourth Pole Add-On Accessory expands GL0500C1 switch-disconnector assemblies with a dedicated additional pole that closes simultaneously with the main poles. With AC operating voltage compatibility and an IEC conventional free air thermal current (Ith) of 500 A, this GLX42-designated accessory supports robust industrial switching while maintaining consistent operation across all poles for reliable isolation and control.

Rated at Ui 1000 V and Uimp 12 kV, the GLX420500 meets IEC/EN 60947-3 and IEC/EN 60947-1 for assured compliance in UK panel builds. Its single-pole architecture integrates directly with GL0500C1 devices, preserving coordinated closing across phases. Backed by Lovato quality and sustainability certification, it offers a dependable way to extend functionality without compromising standards or performance.
