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.

Parts List and Inspection

Items included in the package consist of the following:

• 1 TPS3 11 SPD including 3’ (~1m) conductors

• 1 User’s Manual (this document)

If the Flush Mount Kit was ordered, additional parts are supplied as

follows:

• 1 Flush Mount Plate

• 1 Flush Mount Installation Instructions

• 4 Mounting Screws

Carefully inspect each item in the package for signs of damage. If

damage is found, please contact Siemens TPS Technical Support:

1.888.333.3545. For more information about this product or other

Siemens products, visit www.sea.siemens.com.

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.
