Diversified industrial manufacturer Eaton Corporation has introduced a new line of molded case circuit breakers (MCCBs) for commercial and utility scale photovoltaic systems. Used in solar combiner and inverter applications, Eaton PVGard circuit breakers are rated up to 600A at 1000V DC. The MCCB meets UL-489B.
“Circuit breakers play a critical role in delivering solar energy,” says Heejung Pudner, product manager at Eaton. “Designed to PV specific criteria, Eaton PVGard circuit breakers are engineered to enhance safety, increase PV system reliability, provide robust performance and improve sustainability.”
The circuit breakers provide load and no-load switching, interruption at low fault current levels and ambient cycling over a wide temperature range for performance required in PV environments, and they are reusable after clearing an electrical fault. Additionally, Eaton DC breakers have a variety of accessories to provide PV string status, enable remote tripping, meet lock-out/tag-out safety standards and be customized to project specific requirements.
