Choosing the right DC circuit breaker
When purchasing a DC MCB , there are three core points: matching the voltage and current of the system, ensuring that protection does not "fail" under extreme operating conditions, and controlling the full...

• 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.
