Selfs - Current--compensated Noise Suppression Chokes - FAMILLE 38H31 SM 38H36 SM



SOCKET VERSION Horizontal mounting Voltage 380 Vac
Current 6 to 16A

These chokes are fitted with high-permeability toroid core (ferrite). They are mainly used as power line
filter in three-phase networks to prevent both the spread of parasitic noise from the electrical
equipment, and the effects of line noise on the equipment itself.
