ABB SACE Tmax-T7N-D PV 1000M 4PR6 Photovoltaic Circuit Breaker

ABB SACE Tmax T7N-D PV 1000M is a four-pole molded-case circuit breaker designed for photovoltaic installations, providing protective isolation for DC circuits up to 1000 V. It is rated for 1000 A and listed for UL 1000 V DC operation in a 4-pole configuration with front-terminal connections, carrying the UL MCS designation in the T7N-D/PV 1000 MCS UL 4p F F M 1000V DC variant. The T7N-D/PV version is specifically intended for PV applications, enabling safe disconnection of DC wiring aboard solar arrays. Typical uses include safeguarding PV strings, DC distribution within solar power systems, and isolation of PV circuits in combiner boxes and inverters where a rugged, front-terminal four-pole MCCB is required.
