Changeover Switch FAQs
What is a changeover switch used for?
A changeover switch transfers a load between two power sources, such as utility and generator supplies or redundant power sources. Manual changeover switches require an operator to select the source, while automatic transfer switches can perform the transfer automatically.
What ratings are available for Telergon AC changeover switches?
Telergon manual AC changeover switches are available from 63A to 1250A at 400VAC. Automatic transfer switches are available from 63A to 630A at 415VAC. Available pole configurations and operating features vary by series.Â
What is the difference between a manual changeover switch and an automatic transfer switch?
A manual changeover switch requires an operator to select between available power sources. An automatic transfer switch monitors the sources and can transfer the load automatically according to its control functions and settings. Telergon C1 and C2 ATS products provide automatic source-transfer functions, with features varying by series.
