8311-3: 8x IEC C13          8311-4: 8x IEC C13 (RCM Type A)
Outlets of 8311-3/-4 not switchable.

Key Features

• Precise current metering of up to 9 units and residual current (RCM for 8311-4)
• 1 connector for plug-and-play sensors
• Fast and easy installation
• NTP function can be activated
• Supports Radius- und Modbus TCP protocol

Metering function

• Power consumption metering (kwH) with 2 energy counters: one counter counts consistently, the other counter is resettable
• Metering of current (A), voltage (V), phase angle, power factor, frequency (Hz), active power (W), apparent power (VA) and reactive power (VAr)
• Metering of differential current type A (mA)
• 1 connector for combined plug-and-play sensors (temperature, humidity and air pressure) to prevent often occurring physical hazards like overheating and increased humidity or air pressure
