Why Choose the Lovato GL1000C1 Switch Disconnector?
The Lovato GL1000C1 is a heavy-duty three-pole 1000 A IEC/EN switch disconnector designed for safe isolation and load switching in high-current industrial power-distribution systems. Part of Lovato Electric's GL series, it is engineered for demanding switchboards, machinery and energy-intensive electrical installations.
The GL1000C1 carries a conventional free-air thermal current of 1000 A and maintains its full 1000 A AC-21A rating from 400 to 1000 V AC. It is also rated at 1000 A AC-23A at 400 and 500 V, providing substantial load-breaking capability for demanding industrial applications.
With a 1000 V insulation voltage, 12 kV impulse withstand voltage and 20 kA short-time withstand current for 1 s, the GL1000C1 is built for high-power installations. The unit mounts directly to a plate and is supplied without a handle, allowing the appropriate Lovato operating accessories to be selected for the installation.

Reliable High-Current Isolation
The Lovato GL1000C1 is engineered for applications where dependable isolation must be maintained at very high operating currents. Its 20 kA one-second short-time withstand rating, 50 kA conditional short-circuit capability and substantial AC-23A making and breaking capacities make it suitable for demanding industrial power-distribution duties.
Visible contacts within the GL heavy-duty platform support clear isolation, while the switch's plate-mounted construction is suited to large switchboards and distribution assemblies. Compatible Lovato operating handles, shaft extensions and other GL accessories allow the installation to be configured to suit the required panel arrangement.
Typical Applications
- High-current industrial switchboards.
- Main low-voltage distribution panels.
- Industrial machinery and production systems.
- High-power feeder isolation.
- Motor and heavy-load switching applications.
