£1,422.08
The Lovato GLCMB0200A230 is a high-capacity motorised three-pole changeover switch designed for automatic transfer between two independent power sources in industrial, commercial and critical infrastructure applications. Manufactured to IEC/EN/BS 60947-3 and IEC/EN/BS 60947-6-1 standards, it provides reliable source transfer for standby generators, UPS systems and automatic transfer switch (ATS) panels.
Part of the proven Lovato GLCM series, the GLCMB0200A230 combines robust switching performance with a dependable motor-operated mechanism, enabling safe, automatic transfer between utility and backup power supplies. The compact design simplifies switchboard integration while delivering excellent electrical endurance and long service life.
With a 200 A IEC thermal current rating, a 208–277 V AC motor supply and a three-pole configuration, this changeover switch is ideally suited to high-current automatic transfer applications where continuity of supply is essential.
The GLCMB0200A230 employs a motor-driven break-before-make mechanism that safely transfers loads between two independent electrical supplies. During each switching operation, the connected load is disconnected from the active source before the alternative supply is connected, preventing the two sources from being connected together.
Its 208–277 V AC motor supply makes it suitable for generator controllers and ATS systems using AC control voltages, while its high switching capacity and long mechanical endurance provide dependable operation in demanding electrical installations.
