£1,651.16
The Lovato GLC0400T4C1UL is a heavy-duty four-pole manual changeover switch designed for safe transfer between two independent electrical supply sources in demanding industrial and commercial low-voltage installations. As part of the Lovato GLC UL changeover switch series, it is built for reliable source selection, isolation and transfer switching applications where robust performance and recognised compliance are essential.
This switch is engineered for high-current power distribution systems requiring dependable manual operation and clear switching positions. Its UL1008 transfer switch rating, strong mechanical construction and screw-on-plate mounting make it suitable for panel builders, OEMs and electrical engineers working with standby power, industrial switchboards and critical electrical infrastructure.
With a rated conventional free air thermal current of 400 A, a four-pole configuration and support for AC systems up to 690 V IEC and 600 V UL, the GLC0400T4C1UL is ideal for mains-to-generator changeover, three-phase plus neutral switching, industrial distribution panels and high-current power transfer applications.
Changeover switches such as the Lovato GLC0400T4C1UL allow operators to manually transfer electrical loads between two independent power supplies while providing a clear isolated OFF position. This is commonly required in standby generator systems, industrial distribution networks and applications where reliable manual source selection is essential.
The four-pole design enables simultaneous switching of the three-phase conductors and neutral conductor, supporting complete source separation in suitable installations. Its UL1008 certification, high current capability and durable construction make it a dependable choice for critical power transfer and industrial electrical control systems.
