Power+™ Control Units
Chapter 1. Introduction
Following the protective function letters is a two-character
code indicating the type of target module installed (if
any), as listed in Table 4.
Suffix Target Module Cat. No.
(none) TARGET00 (blank)
T2 TARGET02 (with GF)
Table 4. Control Unit catalog number code indicating the
Target Module installed.
Finally, if the Control Unit was ordered as a replacement,
the letter “R” is appended to the catalog number.
For example, a Control Unit with catalog number
D220T2R has the following functions:
D – Control Unit for Power Break II switch
2 – Maximum CT rating of 2000 A
20 – Switch current sensor (CT) of 2000 A
T2 – Target module with ground-fault trip indication
R – Control Unit was ordered as a replacement
1–5 Rating Plugs
A rating plug, shown in Figure 1, is supplied in the switch
with a rating coordinated to that of the current sensor. A
rating plug must be replaced only with a unit with the
identical rating.
Figure 1. Power+ rating plug shown with ground-fault
protection function.
Ground-Fault Protection
Ground-fault protection with Power+ Control Units is pro-
vided as an option in the rating plug. Ground-fault
protection is activated by installing a rating plug with the
ground-fault option into the Control Unit. The pickup
and delay settings available with the switches on the rating
plug are described in Chapter 2, Control Unit Setup .
To order a rating plug with the ground-fault protection
function, append “GF” to the catalog number of the rating
plug with the desired sensor and plug rating.
WARNING: Rating plugs equipped with ground fault
must be replaced only with other ground-fault-equipped
rating plugs. Failure to do so could result in personal
injury or death, as well as damage to equipment.
AVERTISSEMENT: Les calibreurs munis d’un détecteur
de défaut de mise à la terre ne doivent être remplacés
que par des calibreurs munis d’un détecteur de défaut de
mise à la terre. La non application de cette directive peut
entraîner des blessures ou même provoquer la mort ainsi
qu’endommager l’équipment.
1–6 Equipment Interfaces
Power+ Control Units do not usually require connections
within the equipment, since all wiring is contained within
the switch. The only connection is for the neutral sensor,
which uses a special dedicated disconnect.
CAUTION: Neutral current sensors are required for sin-
gle-phase, three-wire and three-phase, four-wire systems.
When the Control Unit is connected to a three-phase,
three-wire system, the neutral sensor terminals of the
switch are left open. Do not short any neutral current
sensor terminals in a three-phase, three-wire system, as
this could result in damage to, or malfunction of, the
electrical system.
ATTENTION: Des capteurs de courant de neutre sont
nécessaires pour les systèmes à phase simple, trois câbles
et trois phases, quatre câbles. Lorsque l'unité de contrôle
est branchée à un système trois phases, trois câbles, les
terminaux de capteur de neutre de l'interrupteur sont
laissés ouverts. Ne court circuiter aucun des terminaux
de capteur de courant de neutre dans un système trois
phases, trois câbles, car il pourrait résulter en des
dommages ou un mauvais fonctionnement du système
électrique.
