£1,901.00
The Lovato GLCMB0315T4D024 is a high-capacity 315 A four-pole motorised changeover switch engineered for the automatic transfer of electrical loads between two independent power sources. As part of the proven Lovato GLCM motorised changeover switch range, it provides reliable automatic switching for standby generator installations, automatic transfer switch (ATS) systems and demanding industrial power distribution applications.
Featuring an integrated 24 V DC motor operator, the GLCMB0315T4D024 is designed for seamless integration with ATS controllers, PLCs and generator management systems. Automated switching improves operational safety, minimises downtime and helps maintain continuity of supply for mission-critical electrical installations.
With a conventional free-air thermal current rating of 315 A, a four-pole switching configuration and suitability for systems operating up to 690 V AC, this motorised changeover switch is ideal where complete isolation of all three phases together with the neutral conductor is required.
Motorised changeover switches automatically transfer electrical loads between primary and standby power sources, reducing downtime and eliminating manual switching during power interruptions. When paired with a compatible automatic transfer controller, the GLCMB0315T4D024 provides dependable and safe changeover operation.
Its four-pole configuration switches all three phases together with the neutral conductor, providing complete electrical isolation between power sources where required. This makes the switch particularly suitable for hospitals, data centres, industrial facilities, commercial buildings and other critical infrastructure.
