• Overheating protection 
  NO DANGER OF OVERHEATING INSIDE THE BREAKER BOX
  In case of unsafe temperature levels or rapid temperature increase, device switches off the outputs and sends notification. Internal temperature sensor is measuring the heat every 100 ms.
• Overpower protection
  POWER METERING ENABLED DEVICES PROTECT FROM OVERPOWER DAMAGES
  Detected overpower will lead to outputs switch off by the device and it will immediately send notification. Overpower protection feature protects the device and other electrical equipment from potential damage.
  *Feature is available only for power metering enabled devices
• Overvoltage protection
  PROTECT APPLIANCES FROM OVERVOLTAGE WITH THE POWER METERING SHELLY PRO DEVICES
  Voltage peaks could be dangerous for electrical appliances and machines. To avoid damage to the electrical appliances the device switches off the outputs when overvoltage peaks are detected and immediately sends a notification.
  *Feature is available only for power metering enabled devices
  
• Flame Retardant (V-0)
  FLAME-RESISTANT MATERIALS FOR ENHANCED SAFETY.
  All Shelly Pro components are produced with flame-resistant materials and will keep their construction even when exposed to high levels of heat.
