The Lovato GLCMB0250E110 is a robust and dependable motorised three-pole changeover switch designed to transfer electrical loads between two power sources in commercial and industrial installations. As part of the advanced Lovato GLCM motorised changeover switch series, it provides reliable source selection for switchboards, machinery and power distribution systems where continuity of supply is essential.
This motorised changeover switch combines a high-current switching assembly with an integrated 110–125 V AC/DC motor operator. It can be controlled remotely through compatible automation equipment, control relays or automatic transfer systems, reducing the need for manual switching and simplifying power-source management.
With a conventional free-air thermal current rating of 250 A, a three-pole configuration and support for AC electrical systems up to 690 V, the GLCMB0250E110 is suitable for demanding low-voltage power distribution applications. Its durable construction and compliance with recognised IEC, EN and BS standards make it a dependable choice for professionally engineered electrical installations.
Motorised changeover switches transfer an electrical load between two separate power sources, such as a mains supply and a standby generator. Automated switching helps reduce supply interruptions while allowing electrical distribution systems to respond efficiently when the preferred source becomes unavailable.
The Lovato GLCM series is designed for use in professional switchboards, industrial power systems and automatic transfer installations. Its motorised mechanism enables remote operation from compatible control equipment, helping improve operational safety and simplify the management of primary and alternative power sources.
