Product Description

Product Description

DC load Isolator Switch with IEC standard,Available from 400A-630A-800A 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).
