The Lovato GLCMB0160A230 is a dependable motorised three-pole changeover switch designed to transfer electrical loads between two independent power sources. With a 160 A IEC conventional free-air thermal current and a 208–277 V AC motor supply, it is an excellent choice for automatic transfer switch panels, standby generator systems and critical power distribution applications.
Part of the established Lovato GLCM series, the GLCMB0160A230 combines a robust switching mechanism with motorised remote operation. When connected to a compatible automatic transfer controller, it can support dependable mains-to-generator or source-to-source transfer without requiring routine manual intervention.
The switch is manufactured in accordance with IEC/EN/BS 60947-3 and IEC/EN/BS 60947-6-1. Its high short-circuit withstand capability, 20,000-cycle mechanical life and flexible mounting position make it suitable for demanding commercial and industrial switchboard installations.
The Lovato GLCMB0160A230 uses a controlled changeover sequence with defined I, O and II positions. During a transfer, the connected load is disconnected from the active source before the alternative source is engaged. This break-before-make operation helps prevent the two independent power supplies from being connected together unintentionally.
The motorised mechanism can be controlled remotely and integrated with a suitable automatic transfer controller. The controller monitors the available supplies and commands the switch to transfer the load when the preferred source fails, returns or falls outside configured electrical limits.

It is used to transfer a three-phase electrical load between two independent power sources, such as the mains supply and a standby generator.
The switch has an IEC conventional free-air thermal current rating of 160 A at an ambient temperature of up to 40°C.
Its motor mechanism is rated for a 208–277 V AC supply and has an operating range of 166–332 V AC.
Yes. It can be connected to a compatible automatic transfer controller for controlled transfer between primary and standby electrical supplies.
No. It uses break-before-make operation through a centre-off position, disconnecting the active source before connecting the alternative source.
The manufacturer specifies a 160 A gG fuse for a conditional short-circuit current rating of up to 100 kA rms.
Lovato GLCM motorised changeover switches provide panel builders, electrical contractors, OEMs and system integrators with robust source-transfer solutions for industrial, commercial and critical power applications.
