The H704 Series branch circuit current monitoring system provides a cost-effective solution for electrical load management, making it ideally suited for applications where load capacity requirements are dynamic, such as the data storage industry, lighting panels, etc.

The H704 monitors the current draw of each 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 (see graph, facing page). 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

• Up to 63 H704s can be networked on one Modbus RS-485 drop...simplified wiring
• Reports current consumed on each circuit in the panel board...one product covers multiple points
• 3/4 or 1 inch on center current sensors accommodate standard breakers...easy installation
• Provides Modbus registers for current limit warnings and alarms...prevents breaker trips
• Integrates with available network display for local indication
• Built-in ability to set the orientation and numbering of the circuits
