£1,494.19
The Lovato GLCMB0200T4A230 is a high-performance 200 A four-pole motorised changeover switch designed to transfer electrical loads between two independent power sources. Part of the dependable Lovato GLCM range, it provides a robust switching solution for automatic transfer switch panels, standby generator systems and commercial or industrial power distribution installations.
An integrated 208–277 V AC motor operator enables the GLCMB0200T4A230 to be controlled remotely using a compatible automatic transfer controller, PLC or building management system. Its motorised mechanism helps reduce manual intervention, improve operating safety and restore power efficiently when the preferred electrical supply becomes unavailable.
The switch has a conventional free-air thermal current rating of 200 A and can be used on electrical systems with operating voltages up to 690 V AC. Its four-pole configuration switches three phase conductors and the neutral, making it particularly suitable for applications where complete separation between mains and standby power sources is required.
A motorised changeover switch provides a controlled method of transferring an electrical load between two power sources, commonly a utility supply and a standby generator. When combined with a suitable automatic transfer controller, the system can detect a supply failure, initiate the standby source and operate the switch without requiring an engineer to perform the changeover manually.
The GLCMB0200T4A230 uses mechanically defined switching positions to help prevent the two supplies from being connected to the load simultaneously. Its four-pole arrangement also switches the neutral conductor, supporting installations in which complete electrical separation between sources is required by the system design.

The GLCMB0200T4A230 is used to transfer an electrical load between two independent power sources, such as a mains supply and a standby generator. Its motorised mechanism allows the changeover process to be controlled remotely or automatically.
The switch has an IEC conventional free-air thermal current rating of 200 A. The suitability of this rating for a specific installation must be confirmed against the load, utilisation category, conductor size and protective-device requirements.
The integrated motor operator is rated for a 208–277 V AC supply and has a specified operating range of 166–332 V AC.
Its four-pole configuration switches all three phase conductors together with the neutral. This supports power systems where the neutral must be disconnected and transferred with the phases to maintain complete separation between sources.
Yes. The motorised switch can be integrated with a compatible automatic transfer controller to create an ATS system for transferring a load between mains, generator or other alternative power sources.
The specified operating time is approximately 0.55–0.89 seconds for an I–O or O–I operation and 1.0–1.4 seconds for an I–O–II or II–O–I transfer sequence.
The GLCMB0200T4A230 conforms to IEC/EN/BS 60947-3 for switches and switch-disconnectors and IEC/EN/BS 60947-6-1 for transfer switching equipment.
Lovato motorised changeover switches provide switchboard manufacturers, electrical engineers and system integrators with a dependable solution for remotely controlled and automatic power-source transfer in commercial and industrial installations.
