Transient Protection System Many types of equipment, especially computers and office
(TPS3) equipment, are susceptible to the high energy levels associated
with electrical surges, which can be caused by lightning or
electrical equipment operation. Any component between the
source of the surge and ground can be damaged. In response
to this problem, Siemens Transient Protection System (TPS3)
offers UL 1449 3rd edition surge protection devices (SPDs) to
fit every level of the electrical distribution system.

efficiency standards and our Ultra Efficient motors with
our exclusive die cast copper rotor technology exceed NEMA
Premium efficiency standards.
