General data
●   Plastic case and insulating resin are self-extinguishing.
●   Fixing holes in the case moulding for two positions at right angles.
●   Direction of the current: A primary current flowing in the direction of the arrow results in a positive secondary output current from terminal M. 		 Secondary connection
● Molex HE14 connector (ref.: 22-11-10 31)
● JST connector (ref.: B3P-VH)
● 3 x 200 mm cables (cross section 0.38 mm2)
 Primary connection
Hole for primary conductor. The temperature of the primary conductor in contact with the case must not exceed 100°C.
