Lovato GLX420600UL is a 600 A UL98 fourth-pole add-on with simultaneous switching operation for the Lovato GL0600C1UL switch disconnector.
£334.31
The Lovato GLX420600UL is a purpose-designed fourth-pole add-on for the Lovato GL0600C1UL switch disconnector. As part of the Lovato GL UL98 switch disconnector accessory range, it enables a standard three-pole GL0600C1UL installation to be expanded to a four-pole switching configuration.
The GLX420600UL operates with simultaneous closing action alongside the main switch disconnector poles. It carries a 600 A UL general-purpose current rating and is certified to UL98 / CSA C22.2 No. 4, making it suitable for high-current industrial switching and isolation equipment intended for North American applications.
For IEC applications, the fourth pole has a conventional free-air thermal current rating of 630 A, a rated insulation voltage of 1000 V and a rated impulse withstand voltage of 12 kV. Its dedicated construction allows it to integrate directly with the GL0600C1UL, providing panel builders with a matched Lovato solution for creating a four-pole high-current switch disconnector.
A fourth-pole add-on allows a compatible three-pole switch disconnector to be expanded where four switched conductors are required. By operating simultaneously with the main poles, the additional pole becomes an integral part of the switching sequence rather than functioning as a separate manually operated component.
The Lovato GLX420600UL is engineered specifically for the 600 A UL98 GL0600C1UL platform. Its high current capability, 1000 V insulation rating and matched mechanical design make it suitable for panel builders and equipment manufacturers creating four-pole industrial isolation and power-distribution assemblies.
