The Lovato GLCMB0125T4E110 is a robust and dependable motorised four-pole changeover switch designed to transfer electrical loads between two independent power sources in commercial, industrial and critical power installations. As part of the trusted Lovato GLCM motorised changeover switch series, it provides reliable source selection for automatic transfer panels, generator systems and low-voltage electrical distribution networks.
Featuring an integrated 110–125 V AC/DC motor operator, this changeover switch supports remote operation through automatic transfer controllers, PLCs and compatible power management equipment. Its motorised mechanism reduces the need for manual switching, improves operational safety and helps maintain continuity of supply when transferring between primary and alternative power sources.
With a conventional free-air thermal current rating of 125 A, a four-pole switching configuration and suitability for electrical systems up to 690 V AC, the GLCMB0125T4E110 is ideal for installations where all three phases and the neutral conductor must be switched. Its durable construction and conformity with recognised IEC, EN and BS standards make it a reliable choice for professionally engineered power systems.
Motorised changeover switches transfer electrical loads between two separate power sources, such as a mains supply and a standby generator. Automated operation helps reduce supply interruptions, minimises manual intervention and allows electrical distribution systems to respond efficiently when the preferred power source becomes unavailable.
The four-pole configuration of the GLCMB0125T4E110 switches all three phase conductors together with the neutral conductor. This makes it particularly suitable for installations where complete separation between power sources is required, including generator systems, commercial buildings and critical power distribution networks.
