Introduction
Overview
The Eaton S801+ Soft Starter from Eaton’s electrical
business is an electronic, self-contained, panel- or
enclosure-mounted motor soft-starting device. It is intended
to provide three-phase induction motors with a smooth start,
both mechanically and electrically. The S801+ Soft Starters
utilize six SCRs connected in a full wave power bridge.
Varying the SCR conduction period controls the voltage
applied to the motor. This in turn controls the torque
developed by the motor. After the motor reaches speed,
internal contacts are closed to bypass the SCRs.
The S801+ Soft Starter utilizes a Control Interface Module
(CIM) that allows the user to configure the device and
evaluate fault codes for troubleshooting.
The S801+ is designed to fulfill the industrial service
requirements for applications such as Chillers, Pumps and
Machine Tools that require less than 100% of the motor’s
rated starting torque for worst case starting condition.
The S801+ meets all relevant specifications set forth
by UL 508, CSA 22.2-14-1995 IEC 60947-4-2, and
CCC GB14048.
