H663
DESCRIPTION
The H663 Series split-core branch circuit current monitoring system provides a costeective solution for electrical load management. It is ideally suited for applications
where load capacit y requirements are dynamic, such as data centers and sales oors.
The split-core housing makes this device perfect for retrot 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 (see graph, facing page).
Additional capacity can then be added, or loads balanced, to prevent costly downtime
from overloaded circuits and unexpected breaker trips.
power/energy monitoring
APPLICATIONS
● Retrotting panelboards
● Cost allocation
● Protecting against overload
● Managing and balancing loads
● Lighting circuits
FEATURES
● 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
● Split-core design and network compatibility... ideal for retrot applications
● Up to 63 H663s can be networked on one Modbus RS-485 drop...simplied
wiring
● Split-core CTs are perfect for quick installation on critical load applications that
can’t be powered down
