The E30E Series ethernet-enabled Solid-Core Panelboard Monitoring System provides a cost effective solution for electrical load management, making it ideally suited for applications where loads are dynamic, such as the data storage industry, lighting panels, etc.

The E30E224 kit with Advanced functionality monitors voltage, current, power and energy consumption for mains and branches in a panelboard. The accumulated information can be accessed via an ethernet or serial communications interfaces using Modbus,BACnet or SNMP protocols.  As any circuit approaches the user-configured thresholds, alarm indicators are triggered, preventing costly downtime from overloaded circuits or failed loads.

The E30E224 kit includes an Advanced measurement unit with metal housing, two strips of 12 ea 100A solid core current transducers spaced 18 mm apart and two 4 ft round ribbon cables for connecting the CT strips to the main board. Both flat and round ribbon cables in various lengths are available for use with this product to fulfill your application needs (see CBL). CTs for monitoring mains and neutrals are sold separately (see H681x-xxxA-.3V, E681xxxxxx, E682xxxxxx).
