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.

Agency Approvals

1. 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.

2. 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.
3 . The CE mark indicates RoHS2 compliance. Please refer to the CE Declaration of
Conformity for additional details.

Specification Note: For CE compliance, conductor shall be insulated according to
IEC 61010-1

Do not use the LCD as evidence of applied voltage.

ORDERING INFORMATION

MODEL AMPERAGE RANGE1STATUS OUTPUT

H11D

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

2. Listed for use on 75 °C insulated conductors.
