Lovato GLX420320 IEC/EN fourth pole add-on 320A

Why Choose the GLX420320?

The Lovato GLX420320 fourth pole add-on accessory extends GL0320C1 switch disconnectors to four-pole operation with simultaneous closing aligned to the main poles. Engineered for AC systems, it provides a conventional free air thermal current Ith of 320 A. Built to IEC/EN 60947-3 and 60947-1, this GLX42-designated module integrates cleanly into industrial panels requiring dependable isolation and consistent switching performance.

With a rated insulation voltage Ui of 1000 V and a rated impulse withstand voltage Uimp of 12 kV, the GLX420320 maintains reliability across demanding applications. Operating currents are 320 A for AC21A, AC22A and AC23A duty at 400 V, 500 V and 690 V, supporting straightforward specification for OEM builds, panel upgrades and maintenance replacements.
