£1,550.34
The Lovato GLCMB0250D024 is a robust and dependable motorised three-pole changeover switch designed for transferring electrical loads between two power sources in commercial and industrial installations. As part of the advanced Lovato GLCM motorised changeover switch range, it provides automated 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 a 24 V DC motor operator, allowing it to be controlled remotely through compatible automation equipment, control relays or power management systems. Its motorised operation reduces the need for manual switching and supports reliable transfer between normal and alternative electrical supplies.
With a conventional free-air thermal current rating of 250 A, a three-pole configuration and an operating voltage of up to 690 V AC, the GLCMB0250D024 is suitable for demanding low-voltage power distribution applications. Compliance with IEC, EN and BS changeover switch standards makes 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 minimise supply interruptions while allowing power 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 automated transfer installations. Its motorised mechanism allows remote operation from compatible control equipment, helping improve operational safety and simplifying power-source management.
