All specifications are subject to change without notice.GENERATOR CONTROLSThe above Figure shows the Generac GENprotect thermal protection curve for use in protection and coordination studies. The alternator <br />Thermal Damage Curve is shown just to the right of the GENprotect protection curve. If the alternator load is greater than the thermal damage <br />protection curve for the alternator, the generator set will trip off-line. For example, an overload current of 110% for 75 seconds causes an <br />overload alarm and will trip the generator off-line, shutting down the engine. GENprotect will provide generator protection over a full range of <br />time and current, from instantaneous faults to overloads lasting several minutes. An advantage of GENprotect over a MCCB is that GENprotect <br />allows for downstream breakers to clear faults without tripping the generator off-line, providing selective coordination with the first level of <br />downstream breakers. <br />GENprotect ™ <br />Seamless Protection for Industrial Power Generators <br />Docusign Envelope ID: 2F58BEE5-DDBE-42EB-8DFA-5E2508488B04
