Product Description
Factory Price EHDN/EHDT 1000V/1500V 400A 630A 800A 2P/4P Load Break Switch

DC load Isolator Switch with IEC standard,Available from 160A-250A-315A-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.
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).
