Enhance your GA100C installation with the Lovato GAX42100C fourth pole add-on accessory. This 1‑pole module provides simultaneous closing operation with the existing switch poles, delivering consistent performance at 100 A Ith in AC applications. Built as a dedicated accessory for the GA...C version, it expands switching capability while maintaining the original device’s operating sequence.
Conforming to IEC/EN 60947-3 and IEC/EN 60947-1, with UL508, UL98 and CSA C22.2 recognition, this Lovato accessory supports compliant, reliable assemblies. Its single-pole design integrates cleanly as a fourth pole on GA100C devices, keeping actuation synchronised across poles. Backed by Sustainability certification, it offers a practical, standards-aligned way to extend AC switching arrangements without redesigning your panel.
