TPS3 03’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 03 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 Technical 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.

SPDs on Ungrounded Systems
Caution –
Ungrounded systems are inherently unstable and can
produce excessively high line-to-ground voltages during certain fault
conditions. During these fault conditions, any electrical equipment
including an SPD, may be subjected to voltages which exceed their
designed ratings. This information is being provided to the user so
that an informed decision can be made before installing any electrical
equipment on an ungrounded power system.
