SunSwitch DC Breaker 1000V
DC miniature breaker for PV string and inverter DC sides, 1000V rated, magnetic blow-out arc quenching.
Solution
Solar & Storage
DC string protection, isolation and surge protection for PV and battery systems.
Typical protection set
PV fields need DC-rated breakers and fused switch-disconnectors at string and combiner level, plus Type 1+2 SPDs on both sides of the inverter. Battery add-ons reuse the same DC protection family with higher continuous ratings.
Every set below is a starting point: send the load schedule or single-line diagram and our engineers adjust ratings, curves and certification package to the project.
