Grounding Reactor » Selection Table

Select the appropriate grounding reactor by:

1. Determine the maximum secondary voltage of the welding transformer to be protected.

See Column 1 of Selection Guide.

2. Determine the ampere rating of the fuse or circuit breaker installed in the primary circuit to protect the welding transformer.

See Column 2 of Selection Guide.

3. Select type of connection desired.

See Column 3 of Selection Guide.

4. Select grounding reactor model number.

See Column 4 of Selection Guide.
