Siemens TPS3 09 Manual De Usuario

Introduction

Thank you for choosing the Siemens TPS3 09 Surge Protective Device
(SPD). TPS3 09 is a high quality, high energy surge suppressor designed
to protect sensitive equipment from damaging transient overvoltages.
The  TPS3  09  is  parallel  connected  such  that  circuit  ampacity  is
unlimited. Proper installation is important to maximize performance.
Please follow steps outlined herein. These instructions are not intended
to replace national or local codes. Follow all applicable electrical codes
to ensure compliance.

Industry Standards Changes - 2009

UL 1449 Third Edition and 2008 NEC® Article 285 generated substantial
changes.

•

The term TVSS changed to SPD

•

Types 1, 2, 3 & 4 SPDs are created

•

UL  1449  clamping  voltage  performance  testing  changed  from
500A to 3,000A

•

UL 1449 added new I nominal testing (In), which consists of more
rigorous duty-cycle testing

The SPD Type category is important to understand before installing 
any SPD. Type 1 and 2 SPDs are fully UL Listed devices whereas Type 
4 SPDs are UL Recognized devices.

Type  1  –  Installed  on  line  or  load  side  of  the  Main  Overcurrent
Protection (OCP), similar to what you knew as SSA, except now includes
rigorous safety testing. Includes all OCP & safety disconnectors inside
the SPD
Type 2 – Installed on load side of the Main OCP, similar to what you
know as hardwired SPD, and it may require external OCP.
Type 3 – Point of Utilization, direct plug in type devices, similar to what
you know as surge strips. Theses devices are intended for installation
10 meters from the panel (rational based on IEEE Cat. A location).
Type 4 – Surge suppression components, could be a basic component
or a complete module. Type 4 components can be tested for Type 1,
Type 2 or Type 3 applications.

(also coincides with ANSI/IEEE C62.41.2 - 2002 Categories C, B &A)

For further information, please review latest editions of NEC® Art. 285, 
UL 1449, contact your local Siemens sales office or contact Siemens

The TPS3 09 is a Type 1 SPD. Type 1 SPDs are evaluated more rigorously
by UL 1449 for 2008 NEC® Article 285 compliance. Type 1 SPDs and
their connecting leads have been evaluated for line side applications
without need for supplemental overcurrent protection. Type 1 SPDs
include internal overcurrent protection. As a generalization, there are
practical maintenance reasons for installing on the load side of the main
overcurrent device (i.e. Type 2 installation). When connected on load
side of main disconnect, a 30A circuit breaker is recommended due to
10 AWG conductors. The circuit breaker serves as a disconnecting device
and provides NEC® imposed short circuit protection to the conductors
in Type 2 or 4 applications.

Simplified Explanation of Operation

SPDs sense overvoltage and create a momentary short circuit to redirect
harmful surge energy to earth ground. SPD’s are not a one time device.
They reset automatically and wait for the next surge. SPDs are capable
of repeating this function thousands of times.
