Barrier Strip
Filtered Terminal Blocks
The barrier strip filtered terminal block is designed
provide excellent EMI/RFI filtering of AC and DC
power lines and control lines. This terminal block is
available in various sizes, with terminal for soldering
or spade lugs. Application examples include filtering
power supplies in telecommunications equipment,
metering, industrial controls, instrumentation and
EDP equipment.
