DESCRIPTION
The Hawkeye TruStat H11D is a microprocessor based, self-learning, self-calibrating
current switch. It is designed for user ease, providing calibration-free status for
both under and overcurrent, an LCD display, and slide-switch selectable trip point
limits. At initial power-up, the H11D automatically learns the average current on the
line with no action required by the installer. Once a current is learned, the switch
monitors for changes in current greater than the selected range.
APPLICATIONS
● HVAC fans, pumps, and blowers
● Monitoring status of industrial process equipment

FEATURES
● Backlit LCD display...view the monitored current (up to 200A)...eliminates the
need for expensive handheld meters and oers easy visibility in dark enclosures
● Automatic calibration...reduced errors and installation costs
● Slide-switch selectable trip point limits...application versatility
● Microcontroller based learning technology...automatically learns load upon
initial power-up...eliminates labor associated with calibration
● Records and displays the amperage level that trips the alarm...simplies
troubleshooting
● Reset function can be used when unpowered...reduces the possibility of an
undesirable arc ash incident
● Monitors current for both under- and over-load in one package
● 100% solid state...no moving parts to fail
● Small size ts easily inside small starter enclosures...saves space
● Self-gripping iris for easy installation
● Bracket can be installed in three dierent congurations...added exibility
● 5-year warranty

* Trip point switch positions A and B are not for use in applications where the current will uctuate by more than 40% (A) or 60% (B) of the nominal current. If the current will uctuate by more than 60%, use the H11D for on/
o status (position C) only.
** The upper trip limit alarm resets when the current drops by 5% of the learned nominal current limit. The lower trip limit alarm resets when the current rises by 5% of learned nominal current limit.
Specication Note: For CE compliance, conductor shall be insulated according to IEC 61010‑1:2001.
The product design provides for basic insulation only.
Do not use the LCD as evidence of applied voltage.

To enable the upper trip limit alarm, the max. learned current for switch setting “A” is 142A, and the max. learned current for switch setting “B” is 125A.
Switch setting “C” is for on/o status only, so the upper trip limit alarm does not apply.
