What is a Surge Protective Device (SPD)?
A Surge Protective Device (SPD) is an essential electrical component designed to protect electrical equipment from damage caused by sudden voltage spikes, known as surges. These surges can result from
• Quickly dissipate heat and reduce the service temperature
• Single chip voltage up to 750V
• Plug-in clips, Easy module replacement
• Flash Barrier, Prevent arc propagation in current impact
• Use a suitable electrical insulator to keep a 10mm min.safety distance from
the PV-SPD and other grounfed parts in the housing
• The green and red visual indicator flags show the module protective status
(green = good, red = replace)
• Features visual indication and optional remote contact signaling
(floating changeover contact)
• Feature a combined disconnection
• Short-circuiting (shunting) device with safe electrical isolation to Prevent fire
damage due to DC arcs.
