EM13x Series SMART MULTIFUNCTION METER
35
EM133-SE model with measuring nominal current 50A or 20mA (using
HACS), direct connection – nominal voltage input is up to 230(400)
VAC.
Current Input Connection
The EM13X Series consists of five different models according to the
current inputs measurement:
1A nominal current (2A maximum) using internal CT – transformer
operated Connection
5A nominal current (10A maximum) using internal CT – transformer
operated Connection
50A nominal current (63A maximum) using internal CT – Direct
Connection, in EM133-SE model Current Inputs and Voltage Inputs are
internally connected together
20mA nominal current (40mA maximum) using HACS (external CT
provided by SATEC) – Transformer Connection
2.5mA nominal current (5mA maximum) using RS5 (external CT
provided by SATEC) – Transformer Connection
