£1,901.00
The Lovato GLCMB0315T4E110 is a heavy-duty 315 A four-pole motorised changeover switch designed to automatically transfer electrical loads between two independent power sources. As part of the reliable Lovato GLCM motorised changeover switch range, it is ideal for automatic transfer switch (ATS) systems, standby generator installations and demanding industrial or commercial power distribution applications.
Equipped with an integrated 110–125 V AC/DC motor operator, the GLCMB0315T4E110 enables dependable remote and automatic operation using compatible ATS controllers, PLCs and building management systems. The motorised mechanism delivers safe, efficient source transfer while helping to minimise downtime during power interruptions.
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 switch is an excellent choice where complete isolation of all three phases together with the neutral conductor is required.
Motorised changeover switches provide fully automatic transfer between primary and standby power supplies, helping maintain continuity of supply during mains failures. When integrated with a compatible ATS controller, the GLCMB0315T4E110 automatically transfers the load safely and efficiently with minimal interruption.
The four-pole configuration switches all three phase conductors together with the neutral conductor, ensuring complete electrical separation between power sources where required. This makes the switch suitable for data centres, hospitals, manufacturing facilities, commercial buildings and critical infrastructure installations.
