Three Phase Meters
NHP’s range of three-phase meters offer a cost effective, easy to install options for basic energy monitoring.
Features and Benefits
- Compact 4 DIN Size
- Options for basic energy monitoring or billing purposes
- Direct and CT connect options available for application flexibility
- Easy to connect split and solid core CTs saving on installation and setup time.
CT Connect Meters:
The EM210 and EM270 Series have the flexibility to be DIN or panel mounted. With easy to connect CTs they can monitor 2 x three phase or 6x single phase circuits. Split core easy to connect CTs also available for retrofit applications.
