Key Features
E31A kits
Features advanced functionality monitor voltage, current, power 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 any circuit approaches the user-configured thresholds, alarm indicators are triggered, preventing costly downtime from overloaded circuits or failed loads.
E31B kits
Features intermediate functionality monitor voltage, current, power and energy consumption in the mains along with voltage and current in the branches in a panelboard. The accumulated information can be transmitted through the communications interface. Data updates occur roughly every two seconds to provide timely preventative maintenance information. As any circuit approaches the user-configured thresholds, alarm indicators are triggered, preventing costly downtime from overloaded circuits or failed loads.
E31C kits
Features basic functionality monitor current in the mains and the branches in a panelboard. The accumulated information can be transmitted through the communications interface. Data updates occur roughly every two seconds to provide timely preventative maintenance information. As any circuit approaches the user-configured thresholds, alarm indicators are triggered, preventing costly downtime from overloaded circuits or failed loads.
