The H663 Series split-core branch circuit current monitoring system provides a cost-effective solution for electrical load management. It is ideally suited for applications where load capacity requirements are dynamic, such as data centers and sales floors. The split-core housing makes this device perfect for retrofit projects. The H663 monitors the current draw of each critical breaker in a panelboard. The accumulated information can be transmitted to a Modbus host and/or viewed on an optional local display via an RS-485 network. Data updates occur approximately once per second to provide timely preventative maintenance information. As a circuit approaches capacity, warning and alarm levels trigger. Additional capacity can then be added, or loads balanced, to prevent costly downtime from overloaded circuits and unexpected breaker trips.
APPLICATIONS- Retrofitting panel boards
- Allocating load-based costs
- Protecting against overload
- Managing and balancing load
- Lighting circuits
A simple solution for individual circuit current monitoring- The H663 reports current consumed on each circuit in the panel board...one product covers multiple points
- Provides Modbus registers for current limit warnings and alarms...prevents breaker trips
- Integrates with available network display for local indication
