The PT-SMLA Series TVSS Device is the designed for AC Power protection for industrial and commercial
services. This device was engineered for installation on high ampacity service entrances, distribution panels,
and main disconnects to provide robust protection from severe lightning surges and transients.The PT-SMLA
is the perfect TVSS device for protecting expensive industrial and manufacturing equipment. The device can
be installed at the motor control panels or at the load to protect from power supply surges and from the ever-
present internally generated transients in the industrial & manufacturing environment.

* Let-through Voltage Test Results
*Let-through Voltage Test Parameters: Positive Polarity, All voltages are peak (�10%). All tests are static except 150 V MCOV modes. Let-through voltages
on static tests calculated by subtracting sinewave peak from let-through measured from zero. 150 V MCOV mode let-through voltages measured from
the insertion point on the sinewave. (Scope Settings: Time Base = 20 microseconds, Sampling Rate = 250 Megasamples/sec. These settings assure Let-
through voltages test results are accurate). All tests performed with 6" lead length (external to the enclosure), simulating actual installed performance.
MODEL PT-SMLA VOLTAGE PERFORMANCE AND ELECTRICAL SPECIFICATIONS
Surge Current Testing: Single-pulse surge current testing for all modes at rated currents as recommended by NEMA LS1-1992. Single pulse surge current
capacities of 200,000 amps or less are determined by testing all suppression components within each mode as a group. Present industry test equipment
limitations require testing of individual suppression components or sub-assemblies within a mode for single-pulse surge capacities over 200,000 amps.
