Ang DNR PV fuse ay isang mataas na klaseng fuse na disenyo para sa DC proteksyon sa solar at energy storage applications. Ang mga bolt-mount fuses (klase aR para sa semiconductor protection) ay may rating hanggang AC 690V / DC 500V at current mula ilang amps hanggang 400A, kaya sila ay perpekto para sa pagprotekta ng mga inverter, converter, battery systems, at iba pang power electronics.
Ito ay nagbibigay ng mabilis na short-circuit at backup proteksyon para sa mga sensitibong semiconductor devices sa renewable energy systems – halimbawa, frequency converters, rectifiers, inverters, at iba pang power supplies – at batteries, motors, capacitors, at wiring. Ito ang nangangahulugan na ang DNR fuse ay maaaring i-handle ang mga fault sa on-grid o off-grid PV arrays, battery storage banks, EV drive systems, at motor drives.
