The E31 Series Split-Core Panelboard Monitoring System provides a solution for electrical load management, ideal for retro-fit applications for dynamic loads, such as the data storage industry, lighting panels, etc. The adapter boards can be mounted on either DIN Rail or Snaptrack for added flexibility.
The E31 series monitors the current, voltage, and energy consumption of each circuit in a panelboard including the main breaker. The accumulated information can be transmitted through the communications interface. Data updates occur roughly every two seconds to provide timely preventative maintenance information. As a circuit approaches the user-configured thresholds, alarm indicators are triggered, preventing costly downtime from overloaded circuits or failed loads.
The E31A004 kit includes an Advanced featured main circuit board and four CT adapter boards to monitor up to 84 branch circuits. 50A, 100A, and 200A CTs (sold separately) can be used to monitor any circuit. Both flat and round ribbon cables in various lengths are available for use with this product to fulfill your application needs.
