£1,422.08
The Lovato GLCMB0200D024 is a motorised three-pole changeover switch designed for dependable automatic transfer between two independent power sources in commercial, industrial and critical infrastructure applications. With a 200 A IEC conventional free-air thermal current (Ith) and a 24 V DC motor supply, it is ideal for automatic transfer switch (ATS) panels, standby generator systems and critical power distribution installations.
Part of the proven Lovato GLCM series, the GLCMB0200D024 combines a durable switching mechanism with motorised remote operation for fast, reliable source transfer. The motor operator is optimised for 24 V DC control systems, making it particularly suitable for battery-backed generator controllers and emergency power installations.
Manufactured in accordance with IEC/EN/BS 60947-3 and IEC/EN/BS 60947-6-1, the switch provides excellent electrical performance, high short-circuit withstand capability and a robust mechanical design for long service life.
The GLCMB0200D024 operates using a motor-driven break-before-make mechanism, transferring electrical loads safely between two independent power sources. The switch disconnects the active supply before connecting the alternative source, preventing the two supplies from being paralleled.
Its 24 V DC motor supply is ideal for generator controllers and battery-backed ATS systems, delivering dependable operation during utility failures and emergency power transfers.
