4p DIN Rail Mounted DC Isolator Switch Disconnector Used for Photovoltaic System Solar PV Disconnector Switch

Distribution Board DC Isolator PEDSC100R/120R-DB32-X

Products Details

Product Features

  • FIRMLY FIXED:Ding rail and base mounting isolators can be installed in control boxes, distribution boxes and junction boxes. IP40 protection level (Terminal IP20).
  • GOOD CONDUCTION:Self-cleaning contact mechanism, reducing power loss and abrasion, improving the conduction performance, reducing the resistance and energy loss of the switch, extending the lifecycle.
  • EASY WIRING:Compact space saving and V-type bridge jumper design make wiring easier even after the body fixed. The installer can choose series or parallel connections freely.
  • GOOD ADAPTABILITY:Flame resistant materials from world leading manufacturers, with a isolation class of UL94V-0, is employed, so that under ambient temperatures -40 ºC ~ +70 ºC, the product can work without lowering the loads.
  • MODULAR DESIGN:Compact structure and modular design, levels with different versions from 2 to 8 are available.
  • APPROVALS:Rated DC voltage up to 1500V, product carries the most important approvals including TUV, CE(IEC/EN60947-3:2009+A1+A2), SAA(AS60947.3), DC-PV1 and DC-PV2. etc.
  • ADVANCED MECHANICAL DESIGN:Incorporating a user independent switching action, spring mech-anism, to ensure a very fast break/make action, ensuring that the disconnection of the load circuits and suppression of the arc normally occurs within 3ms.
  • NON-POLARITY:Non-polarity DC Isolator Switch
