Molded case circuit breakers for higher-voltage solar power plants

ABB is adding an advanced, new molded case circuit breaker (MCCB) for higher-voltage solar power plants to its Tmax PV range. The breaker, designed to protect combiners, switchgear and inverters up to 1500VDC, is the latest addition to ABB's complete range of protection solutions for utility-scale solar plants. For 1500VDC installations with rated current up to 1200A UL and 1600A IEC, ABB's product range now includes MCCBs and switch-disconnectors. The SACE Tmax PV range makes installation faster and reduces wiring costs for more advanced solar plants, helping utilities and engineers save time. The SACE Tmax PV offers design engineers, panel builders, and inverter manufacturers a single-brand solution for photovoltaic systems installed anywhere in the world. All integrate readily with the electrical and mechanical accessories developed for the SACE Tmax T MCCB range. For systems using string inverters, the SACE Tmax PV range now offers circuit breakers for up to 800VAC, which is type approved to UL 489 specifications and compliant with IEC 60947-2 Standard. ABB's compact circuit breakers can break short circuit currents up to 32kA.
