40ka 2p Type 2 24v Dc spd Surge Protection Device

Product Description

Product Description

Application

This DC surge protective device is designed to protect DC power line systems and other equipment from over-voltage and instantaneous over-voltage damage. It complies fully with the IEC/EN61643-11 standard and is widely used in photovoltaic combiner boxes, power inverters, DC distribution cabinets, and similar systems. It offers the advantages of large discharge current, fast response time, and low residual voltage.

Features

  • Plug-in type surge protective device design.
  • Visible indicator window: green indicates normal operation, red indicates defect.
  • Double protection mechanism featuring fusing and over-current prevention.
  • Remote signal interface enables convenient remote control capabilities.
  • Maximum discharge current can endure up to 40kA (8/20µs). Type 2 / Class C surge protection.

Installation Instructions

  • Ensure the power is completely turned off before connecting the surge protection device to the system.
  • The ground wire should be kept as short, straight, and thick as possible to minimize the influence of distributed inductance on lightning discharge.
  • No specialized maintenance is required. If a surge protector fault occurs, the equipment connected to the remote signal will send an alarm. Simply turn off the power and replace it with a new SPD module.
