>NBH Series
Ultra high-attenuation type(2-Stage filter)(Single Phase)
Difference from old single phase 250V noise filters:
(1) Can select leakage current
(2) Withstand voltage 4,000VAC(Line to ground capacitor code -000 to -471)
(3) Push-down style terminal block prevents screw drop-out and cover loss
Can be used for many purposes.

Note when installing the noise
filter on a DIN rail.
When the noise filter is grounded through the
DIN rail, the proper noise attenuation may not be
achieved.
Be sure to connect the protection earth (PE) of
the noise filter body to the earth.
