Reliable Automatic Source Transfer
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.
Typical Applications
- Automatic transfer switch (ATS) systems.
- Mains-to-generator changeover panels.
- Industrial power distribution.
- Commercial buildings.
- Data centres.
- Healthcare facilities.
- Utilities and infrastructure.
- OEM electrical control panels.
- Emergency and standby power systems.
