PURPOSE OF MANUAL
This manual (Issue 2.0) describes the Basic Version and all options for 7100S series
solid state contactors with current ratings of up to 250 A.
General information about the digital communication option is presented in the
technical specifications (section 1).
The operation of 7100S units with this option and the operation of the digital
communication are described in the ‘7000 Series. Digital Communication’ manual
(part number HA176664ENG available later).

Applicable standards
EUROPEAN DIRECTIVES AND APPLICABLE STANDARDS
COMPLIANCE WITH PRODUCT STANDARD
7100S products comply with the terms of product standard EN 60947-4-3
‘Contactors and motor-starters - AC semiconductor controllers and contactors for non-
motor loads’. The number of this standard is indicated on the front panel label.
CE LABELLING
7100S products, installed and used in accordance with their user manual, bear CE labelling
to indicate compliance with the essential requirements of:

Chapter 1 IDENTIFICATION
GENERAL PRESENTATION
7100S series solid state contactors are used to control the electrical power of single phase
industrial loads. The load controlled may comprise low temperature coefficient resistive
loads or short wave infrared (SWIR) elements.
Current ratings vary from 16 A to 630 A (see coding), at voltages of 100 V to 690 V.
7100S series power thyristor units (rating of up to 100 A) comprise two channels, one
controlled by thyristors and one direct internal channel.
7100S units rated 125 A and above only comprise a single controlled channel.
