QCPort Starter Network
Adapter Product (QSNAP)
Product Description
The Cutler-Hammer
®
QCPort Starter
Network Adapter Product (QSNAP)
from Eaton’s electrical business is a
front-mount device providing commu-
nication capability, control and moni-
toring to Intelligent Technologies (IT.)
Electromechanical Starters, as well as
the S751 and S752 Soft Start, as listed
in Tables 75 – 77.
The IT. QSNAP has an optional HANDS/
OFF/AUTO (HOA) module that enables
the starter to be operated in hand
mode; even if the QSNAP is not pow-
ered. The HOA option is used for cus-

manual control in conjunction with
industrial network communication
capabilities.
With the addition of a D64 zero
sequence CT, the QSNAP can be
enabled to detect ground faults for
added protection.
