Advantagia principalia in quattuor dimensionibus consistunt: accuratio protectionis, adaptabilitas scenarii, durabilitas et facilitas installationis:
1.Protectiones praecises multae ad pericula ex defectibus DC eliminanda
2.Adaptabilitas omnium scenariorum ad diversitates distributionis potentiae DC satisfaciendas
3.Design altae durabilitatis ad costus operationis et maintenance posteriores minuendos
4.Installatio modulata ad efficaciam integrationis systematum distributionis potentiae augendam
Commutator GRM3DC est dispositivum electricum specialiter pro systemate distributionis potentiae DC, cum tensione operativae nominatae a 1000VDC ad 1500VDC, ambitu currentis nominati a 100A ad 1250A, et maxima capacitate interruptoria nominata usque ad 80kA. Integrans tres functiones nucleares, inter quas protectionem longam propter overload, protectionem instantaneam propter short-circuit, et protectionem contra connectionem inversam, hoc productum utitur corio ex alliage PC/ABS flammifugae fortis et designo structurae modulare. Id convenit ad scenariorum distributionis potentiae DC sicut stationibus PV, systematibus conservationis et stationibus communicationis, et potest directe congrui cum combiner box, inverter, et converteribus conservationis, ad stabilitatem et securitatem operationis systematis DC assecurandam.
