The Lovato GLC1000C1 is a heavy-duty three-pole changeover switch designed for reliable switching between electrical power sources in industrial power distribution, machinery and control systems. As part of the Lovato GLC changeover switch series, it provides robust switching performance for high-current AC installations where dependable source selection and circuit isolation are required.
This changeover switch combines high electrical ratings with durable mechanical construction for demanding industrial environments. Its three-pole configuration enables simultaneous changeover of three conductors, while screw mounting onto a plate makes it suitable for integration into switchboards, distribution panels and industrial control cabinets.
With an IEC conventional free-air thermal current of 1000 A, the GLC1000C1 provides an AC-31B operational current of 1000 A at 400–690 V AC. It also supports demanding AC-32B and AC-33B switching duties, providing a versatile solution for high-current power source changeover applications.
Changeover switches such as the Lovato GLC1000C1 provide controlled switching between electrical supplies while enabling dependable circuit isolation. This makes them particularly suitable for installations requiring selection between alternative power sources, such as mains and generator supplies, or between separate distribution feeds.
The GLC1000C1 is engineered for demanding high-current applications. Its AC-31B, AC-32B and AC-33B operational ratings provide flexibility across different electrical load characteristics, while its high short-time withstand capability and robust terminals support dependable integration into correctly designed industrial power distribution systems.
