The H663 provides an easy retrofit, cost-effective solution for electrical load management, particularly in dynamic load environments such as data centers and lighting systems.

The H663 uses multiple split-core mini-CTs to monitor the individual circuits in a panelboard. Accumulated information can be transmitted across an RS-485 network to a Modbus host and/or viewed on an optional local display (H8936). Data updates occur about once per second to provide timely maintenance information. As a circuit approaches capacity, warning and alarm levels trigger to warn of the need for intervention to prevent unexpected breaker trips and costly downtime.
