£1,332.26
The Lovato GLCMB0125T4A230 is a robust motorised four-pole changeover switch designed to automatically transfer electrical loads between two independent power sources in commercial, industrial and critical infrastructure applications. As part of the trusted Lovato GLCM motorised changeover switch series, it delivers dependable performance for generator changeover systems, automatic transfer switch (ATS) panels and low-voltage power distribution.
Featuring an integrated 208-277 V AC motor operator, this changeover switch enables reliable remote operation through PLCs, automatic transfer controllers and building management systems. Automated switching helps reduce downtime, improve operational safety and maintain continuity of power in demanding electrical installations.
With a conventional free-air thermal current rating of 125 A, a four-pole switching configuration and operation on systems up to 690 V AC, the GLCMB0125T4A230 is ideal for applications requiring the switching of both phase conductors and neutral. Its durable construction and compliance with recognised IEC standards ensure long-term reliability.
Motorised changeover switches automatically transfer electrical loads between utility supplies and standby generators, helping maintain power continuity while reducing manual intervention. Four-pole versions are particularly suitable where the neutral conductor must also be switched for improved installation flexibility and electrical safety.
The Lovato GLCM range is designed for switchboard manufacturers, OEMs and industrial engineers who require dependable automatic source transfer. Its integrated motor operator and durable switching mechanism provide reliable long-term performance in demanding electrical environments.
