* 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.
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
