TBU⢠P500-G and P850-G Protectors
Transient Blocking Units - TBU⢠Devices
Bourns® Model P500-G and P850-G
TBU⢠products are high speed, surge
protection components designed to
protect Subscriber Line Interface Circuits
(SLICs) against transients caused by
AC power cross, induction and lightning
surges.
The TBU⢠device blocks surges and
provides an effective barrier behind
which sensitive electronics are not
exposed to large voltages or currents
during surge events.
Agency Approval
