Wiring diagram of a WSP-HSA-40-40-230 mains distribution surge protector

The WSP-HSA/40/40/230RCF is an all-mode Class 2/3 surge arrester to BS EN 61643-11.

Designed for the protection of sensitive equipment, the arrester is an ideal solution for installation at the boundary of LPZ1/LPZ2 to help fulfil the requirements of BS EN 62305.

The arrester features high surge current, all mode protection, thermal and overcurrent protection and a resettable surge counter, with visual, audible and remote indication of the arresters status.

Features and Benefits:

  • Contains a capacitive filter to reduce EMI/RFI, up to 50dB from 10kHz to 1000MHz.
  • Monitors all modes of protection and can be configured to operate at the customers specified surge magnitude.
  • Surge counter trigger peak @ current magnitude 50A pulse or customer selection.
  • Surge counter reset button – cannot be operated accidentally.
  • Equipped with an audible alarm, LED status indication and remote monitoring contacts to warn the user in the event of a surge protection fault.
  • The audible alarm can be silenced via a pushbutton, without affecting other status indication.
