* Trip point switch positions A and B are not for use in applications where the current will fluctuate by more than 40% (A) or 60% (B) of the nominal current. If the current will fluctuate by more than 60%, use the H11D for on/
off 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.
Specification 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 offers 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...simplifies
troubleshooting
●
Reset function can be used when unpowered...reduces the possibility of an
undesirable arc flash incident
●
Monitors current for both under- and over-load in one package
●
100% solid state...no moving parts to fail
●
Small size fits easily inside small starter enclosures...saves space
●
Self-gripping iris for easy installation
●
Bracket can be installed in three different configurations...added flexibility
●
5-year warranty
