Why Choose the Lovato GLCMB0200T4D024UL 200 A 4-Pole Motorised Changeover Switch?
The Lovato GLCMB0200T4D024UL is a heavy-duty 200 A four-pole motorised changeover switch designed for automatic or remotely controlled transfer between two AC power sources. Part of the Lovato GLCM motorised changeover switch series, this model combines four-pole power switching with a 24 V DC motor operator and is designed to UL1008 requirements.
The GLCMB0200T4D024UL provides three stable switching positions — I-0-II — allowing an electrical load to be transferred between two supplies with a defined OFF position between them. Its four-pole architecture enables simultaneous switching of four conductors, making the unit suitable for three-phase systems where the neutral conductor must also be switched.
With a 200 A UL general-purpose current rating, maximum UL operating voltage of 600 V AC and a short-circuit rating of 100 kA rms when protected by the specified Class J fuse, the GLCMB0200T4D024UL is engineered for demanding power-transfer applications. The 24 V DC motor operator provides rapid source transfer, while the switch also carries comprehensive IEC ratings for industrial installations.

Reliable Motorised Power Source Changeover
Motorised changeover switches allow an electrical load to be transferred between two independent power sources using an electrically operated switching mechanism. When integrated with an appropriate transfer controller, the Lovato GLCMB0200T4D024UL can form part of an automatic transfer system for applications requiring controlled switching between normal and alternative supplies.
The four-pole configuration provides switching of all four conductors, while the motorised I-0-II mechanism establishes a defined isolation position during transfer. Its 24 V DC motor supply, rapid switching times and UL1008 rating make the GLCMB0200T4D024UL particularly suitable for industrial, commercial and standby-power distribution systems.
Typical Applications
- Automatic transfer switch assemblies.
- Main and standby power source changeover.
- Utility and generator transfer systems.
- Industrial power distribution switchboards.
- Commercial and infrastructure electrical systems.
- Three-phase systems requiring switched neutral operation.
- Emergency and standby power installations.
