The 100A specification refers to the compatible transfer-switch rating, not the electrical current rating of the coil.

Inspect the related control circuit and 084464 limit switches when diagnosing a failed or shorted coil. Replace additional components only when inspection or testing confirms damage.

Transfer switches contain potentially lethal utility and generator voltage. Installation and testing should be performed by a qualified technician after all utility, generator, and control-power sources have been isolated.

Verify the transfer-switch model, serial number, coil position, and original part number before ordering.
