DC load Isolator Switch with IEC standard,Available from 160A-250A-630A(DC20) in 4P version, acting as a load break switches for DC current. Especially indicated for installations for photovoltaic energy generators, which require a safe disconnection. Standard handle is supplied pad lockable in position "OFF" for maintenance. Bridging links available for series connections. Product Benefits Easy to install • Wiring: Since the switch is non-polarized, all types of wiring and connections are possible. • Easy access without tools, and auxiliary contacts can be integrated without tools. • The mechanical device can be centered to meet the installation requirements. Safe reliable operation • Reliable position indication through visible contacts. • The opening and closing of the switch is fully independent from the speed of operation, ensuring safe operation under all conditions. • High temperature withstand: no derating up to 55 C(131F),functional from -40 to+122F(-40 to +50°C). Designed for harsh environments • Vibration testing (from 13.2 to 100 Hz at 0.7 g). • Choc testing (15 g during three cycles). • Humid temperature testing (2 cycles, 55C/131F with 95% humidity level). • Salt mist testing(3 cycles with humidity storage, 40C/104F, 93% humidity after each cycle).
