Motor FLA ranges are typical. The corresponding trip setting is at
13 x the minimum FLA value shown. Where a 13 x setting is required
for an intermediate FLA value, alternate cam settings and/or MCP
ratings should be used.
For dc applications, actual trip levels are approximately 40% higher
than values shown.
Settings above 130 amperes are for special applications. NEC Article
430-110(a) requires the ampere rating of the disconnecting means to
be not less than 115% of the motor full load ampere rating.
