Product Overview
The H622-20 is a current transducer that senses current (amperage) in the 0 to 20 A range. This represents the
maximum current that can be applied to the monitored conductor. The H622-20 transforms the monitored current
into a 0 to 5 Vdc output suitable for connection to building controllers, or other appropriate data acquisition
equipment. The H622-20 requires no external power supply to generate its output.

product. Follow the instructions during installation.
• Installation, wiring, testing or service must be performed only by
qualied persons in accordance with all applicable codes and
regulations.
• Install the product in an appropriate electrical and re enclosure
per local regulations.
• Do not use the product for life or safety applications.
• Do not install the product in hazardous or classied locations.
• Do not exceed the product’s ratings or maximum limits.
• The product may use multiple voltage/power sources.
• Turn o ALL power supplying equipment before working on or
inside the equipment.
• Use a properly rated voltage sensing device to conrm that all
power is o.
• Do NOT depend on the product for voltage indication.
• Products rated only for basic insulation must be installed on
insulated conductors.
• Current transformer secondaries (current mode) must be shorted
or connected to a burden at all times.

H622-20 Installation Guide
TM
Installation 1. Disconnect and lock out power.
2. Install the mounting bracket to the back of the electrical enclosure, no closer than 1/2” (12 mm) to an uninsulated conductor.
3. Place the conductor to be monitored in the sensing cavity of the current sensor. Ensure the latch is closed. See Notes section
below for currents under 2 A or above 20 A.
4. Wire the output connections between the H622-20 and the controller (0 to 5 Vdc).
5. Reconnect power.
6. Scale the controller software to match the output of the H622-20.
Notes
For load currents greater than sensor maximum rating:
Use a 5 Amp (H681x series) Current Transformer (CT) as shown.

>175 A (sensor max.)

300A:5A

DANGER: 5A CTs can present hazardous voltages.
Install CTs in accordance with manufacturer's instructions.
Terminate the CT secondary before applying current.
NOTICE
RISK OF EQUIPMENT DAMAGE
• Never exceed the current sensor rating.
•
Derate the product’s maximum current for the number of turns
through the current sensor window using the following formula:
Rated Max. Amps ÷ Number of Turns = Max.
monitored Amps
e.g. : 100A ÷ 4 Turns = 25 Amps max. in
monitored conductor
Failure to follow these instructions can result in overheating
and permanent equipment damage.

Troubleshooting
For load currents less than sensor minimum rating:
Wrap the monitored conductor through the center hole and around the sensor body to produce multiple turns through the
“window.” This increases the current measured by the transducer.
Controller must be programmed to account for the extra turns. e.g., if four turns pass through the sensor (as shown) the normal
controller reading must be divided by 4.

Issue Solution
No reading at controller • Check for control voltage at sensor (<5 Vdc).
• Check for amperage in monitored conductor (>2 A).
• Assure that sensor core mating surfaces are clean.
