Remarks：TBC-LTHB can be divided into two types TBC-LTHB1 and TBC-LTHB2

1. All dimensions are in mm.

2. General tolerance ±1mm

3. TBC-LTHB1:With Molex connector(Molex 22011042：5045-04AG，5051-04)

4. TBC-LTHB2: With DG301-5.0-03P connector

Directions for use

1. Is will be in a forward direction when the Ip flows according to the direction of the arrowhead.

2. The primary conductor should be≤120℃.

3. The dynamic performance (di/dt and the response time) is the best when the primary hole is fully filled with the bus bar.

4. The primary turns should be at the top of the sensor for the best magnetic coupling.

5. When the current will be measured goes through a sensor, the voltage will be measured at the output end.

(Note: The false wiring may result in the damage of the sensor)

6. Custom design in the different rated input current and the output current are available.
