£3,091.43
The Lovato GLCMB0200E110UL is a UL 1008-certified motorised three-pole changeover switch engineered for the automatic transfer of electrical loads between two independent power sources. With a 200 A current rating and a 110–125 V AC/DC motor operator, it is ideal for automatic transfer switch (ATS) panels, standby generator systems and mission-critical power distribution applications.
Designed as part of the Lovato GLCM UL range, the GLCMB0200E110UL combines a mechanically interlocked switching mechanism with a reliable motor drive to provide safe break-before-make source transfer. It is suitable for commercial buildings, industrial facilities, healthcare environments, data centres and other installations where continuity of supply is essential.
Certified to UL 1008 and cULus approved, the switch delivers dependable performance, excellent short-circuit withstand capability and straightforward integration into modern automatic transfer systems.
The GLCMB0200E110UL operates using a motor-driven break-before-make switching sequence that disconnects the active power source before connecting the alternative supply. This controlled transfer prevents unintended parallel connection of two independent power sources and provides safe operation during mains failure and generator changeover.
Its 110–125 V AC/DC motor supply provides flexibility for installations using either AC or DC control circuits. Combined with a compatible automatic transfer controller, it delivers dependable source transfer for essential power systems, while manual operation remains available for maintenance and commissioning.
