EHD DC Load Break Switch for PV(1500V 160A~800A)

A range of load break switches specially designed for photovoltaic applications. These devices perform on load making and breaking in all applications of photovoltaic circuits up to 1500 VDC, whether floating, earthed, or bipolar. The load break switches also remain operational under extreme conditions. Load break switches can be used, for example, in photovoltaic circuits, in solar panel farms, during maintenance operations or for emergency switching following a fire or electric shock.

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).
