How to reduce DC Isolating Switch failure frequency?
To fundamentally reduce the failure rate of DC isolating switch, you need a three-pronged strategy: selecting arc-resistant, certified components, such as Suntree's specialized models;

• Quickly dissipate heat and reduce the service temperature
• 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.
