The TPS3 11 is a Type 1 SPD. The TPS3 11 is suitable for use almost
anywhere (not as a plug-in 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, we recommend connecting via a 30A
circuit breaker due to 10 AWG conductors. The circuit breaker serves as
a disconnect switch 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.

Figure 2: DIMENSIONS AND WEIGHT
TPS3 11’s have demonstrated 200kA Short Circuit Current Ratings
(SCCR) including leads (120/240V Split phase models have 100kA
SCCRs). See UL Label markings on SPD or see Data Sheet for specs.)
Supplemental overcurrent protection is not required to protect this SPD.
However, NEC® convention requires that connecting conductors have
overcurrent protection in Type 2 or 4 applications. Follow applicable
codes.

This device features internal overcurrent and overtemperature
protection that will disconnect effected surge suppression components
at the end of their useful life, but will maintain power to the load – now
unprotected. If this situation is undesirable for the application, follow
these instructions for replacing the device. TPS3 11 is ultrasonically
welded closed and contains no user serviceable parts.

Voltage Rating & Application
Before installing SPD, verify by nameplate voltage or model number
that it has the same voltage rating as the power distribution system.
If unsure call Siemens TPS Tech Support at 1.888.333.3545 before
proceeding. The SPDs specifier or user should be familiar with the
configuration and arrangement of the power distribution system. The
system is defined by how the secondary windings of the transformer
supplying the service entrance main or load are configured. This
includes whether or not the transformer windings are referenced to
earth via a grounding conductor. The system configuration is not based
on how any specific load or equipment is connected to a particular
power distribution system. SPDs should be installed per the distribution
system, not per a load or motor’s wiring connection.

For example, suppose a 480V three phase motor appears to be
connected as a 480V Delta. In actuality, the serving distribution
system might be a 480Y/277V grounded Wye, with or without a
neutral pulled to the motor or MCC. The system is still a 480Y/277V
Wye, even though the load is connected as a Delta. A grounded Wye
has a defined reference to ground (i.e., neutral is bonded to ground).
In contrast, some Delta systems are ungrounded, which have no
reference to ground.
