Mechanical characteristics

• General tolerance

± 1 mm

(Unless otherwise specified in the above drawings.)

• Aperture for primary conductor

Ø11 mm

• Connection of secondary

4 pins 0.7 x 0.7 mm2

Recommended PCB hole

1.2 mm

Remarks

• V

OUT is positive when IP flows in the direction of the arrow.

• This transducer induces into the primary circuit a square

wave of 500Hz. This voltage can induce an AC current in the

primary if the primary impedance is low.

• Primary impedance ≥10Ω CT 0.1-P CT 0.2-P CT 0.4-P

OUT by induced current

≤±0.8%

≤±0.5%

≤±0.3% of I

• Temperature of the primary conductor should not exceed

100°C.
