The next generation of enclosed switches
General information
The eOT series of enclosed manual motor controllers are
rotary operated, 3 and 4 pole, 600V Hp rated switches,
housed in thermoplastic/polycarbonate, sheet steel or stainless
steel enclosures. They are suitable for wet and corrosive
environments.

Clean and simple installation
Plastic and Type 1 enclosures have
conduit knockouts provided on the top
and bottom of the enclosure.
Plastic enclosures have a metallic base
plate that electrically bonds together all
conduit hubs installed in the top and
bottom of the enclosure - additional
conduit bonding jumpers are not required.
Plastic enclosure installs flush on
mounting surface, reducing the accu-
mulation of dirt behind the enclosure.
Sealed enclosure cover is water tight,
suitable for hose-down environments
(Type 4X version only).
