Check to ensure that a proper neutral-ground bond is installed between the neutral and ground terminals at the transformer upstream from all 3-Phase WYE, 3-Phase High-Leg DELTA, or 1-Phase SPLIT-PHASE PX3 devices (see NEC article 250.) Lack of a proper bond will damage the PX3 and void the warranty.

Conﬁrm that the environmental conditions are consistent with the following ranges:

• Ambient Temperatures: The PX3 must be installed in an area with a temperature between -13° and +140°F (-25° and +60°C).

• Humidity: The PX3 must be installed in an area with relative humidity between 5% and 95% non-condensing.

• Altitude: The PX3 must be installed in a location where the altitude is below 13,000 feet.

W A R N I N G !

Discontinue installation if (1) your conditions are inconsistent with the checklist above or (2) your conditions cannot be veriﬁed. Call Thomas & Betts Power Solutions’ Technical Support at 800.238.5000 if you have any questions.

Installation Methods (for the design engineer and the installer)

This device features an internal protection that will disconnect the surge protective component at the end of its useful life but will maintain power to the load now unprotected. If this situation is undesirable for the application, follow the manufacturer’s instructions for replacing the device.

The PX3 is a Type 1 SPD which is suitable for use in both Type 1 and Type 2 SPD applications. The PX3 is a one-port SPD and is to be connected in parallel with the electrical system. It may be connected via a circuit breaker, molded case switch, fused switch, or connected directly to the bus of the panelboard or switchboard it is protecting. If direct bus connection is used, Current Technology, recommends that the PX3 be equipped with the optional integral disconnect switch.

Attaching the PX3 to the Panelboard

Current Technology bottom of the panelboard’s enclosure so that the two enclosures are joined without a barrier. It is best to do this before the panelboard is mounted to the structure.

To join the two enclosures, the top or bottom endplate of the PX3 may be removed. Similarly, the top or bottom endplate of most commercial panelboards may be removed.

If your panelboard is TOP-FEED, remove the bottom endplate of the panelboard and the top endplate of the PX3.

™

If your panelboard is BOTTOM-FEED, remove the top endplate of the panelboard and the bottom endplate of the PX3.

™

Attach the PX3 to the panelboard using the supplied collar hardware and screws. Refer to the illustration above showing an PX3 being mounted to the bottom of a panelboard.

Tip: Use of small C-clamps helps hold the parts in place while the screws are inserted and tightened. Note: The panelboard and PX3 enclosures can also be joined together using a close nipple, lockwashers and bushings. Such installations, however, may limit the ability to pass conductors between the two enclosures.

Electrical Connections

tnbpowersolutions.com/current_technology

If you choose to mount the PX3 as a stand-alone enclosure, locate the PX3 enclosure according to the guidelines in the following section “Electrical Connections”.

Phases, Neutral* and Ground: Connect the phase, neutral and ground conductors. Connect the phase conductors to the lugs labeled “A,” “B,” and “C” on the ISM and the ground and neutral* conductors to the lugs labeled “G” and “N.” The terminal lugs of the ISM in the PX3 must be electrically connected by the installer to the appropriate terminals in the panelboard. Before making connections, read and remove the WARNING tag from the ground lug marked “G” on the ISM.

Overcurrent Protection: Connect the phase conductors to circuit breakers in

the panelboard. Current Technology

recommends using circuit breakers in the

range of 60 to 100 amps.

Note: If applicable, please consult specifying engineer’s recommendation prior to making connections.

* Delta-conﬁgured PX3 models do not have a Neutral Lug.

Conductor Routing

The following factors should be addressed during the design of an installation to ensure that there is a suitable place for the PX3 reserved next to its point of connection to the electrical system. The selected mounting location should ensure short conductor runs providing a direct route with a minimum of bends. If bends are required they should be sweeping bends. Do not make sharp 90˚ bends for aesthetic purposes.

These illustration show suggested conductor routing for a top-feed panelboard. Routing in bottom-feed panelboards is similar but reversed. Note that conductors from the PX3 always connect within the panelboards to lugs or breakers closest to the PX3. The lugs on the PX3 ISM may be rotated to facilitate routing.
