• ABB S800PV系列是针对光伏直流系统设计的高性能微型断路器，最高额定电压可达1200V DC，适用于大型地面电站和工商业屋顶的组串保护与隔离。
• The ABB S800PV series is a high-performance miniature circuit breaker family engineered specifically for photovoltaic DC applications, supporting voltages up to 1200 V DC. It is ideal for string protection and isolation in utility-scale solar farms and commercial rooftop installations.
• 1）S800PV-S组串保护断路器提供10A至125A电流范围，分断能力Icu为5kA（依据IEC/EN 60947-2），具备无极性接线、全极安全断开以及可靠的直流电弧熄灭能力，即使在双故障条件下也能稳定工作。
• The S800PV-S string MCB covers rated currents from 10 A to 125 A with a breaking capacity Icu of 5 kA per IEC/EN 60947-2. It features polarity-independent wiring, all-pole safe disconnection, and robust DC arc extinction even under double-fault conditions.
• 2）S800PV-M隔离开关则用于系统隔离，额定电流32A至125A，最高1200V DC，符合IEC 60947-3标准，可作为维护和紧急情况下的可靠断开点。
• The S800PV-M switch-disconnector provides system isolation from 32 A to 125 A up to 1200 V DC, complying with IEC 60947-3. It serves as a reliable disconnection point for maintenance and emergency situations.
• 两款产品均采用35mm DIN导轨安装，工作温度范围–25°C至+60°C，支持丰富的附件，包括分励脱扣器、欠压脱扣器、辅助触头、信号触头、旋转手柄以及远程开关模块S800-RSU，可实现快速监控与远程分断。
• Both variants mount on 35 mm DIN rail, operate from –25 °C to +60 °C, and support a wide range of accessories such as shunt trips, undervoltage releases, auxiliary/signal contacts, rotary handles, and the S800-RSU remote switching module for fast supervision and remote tripping.
