1.2 What are the Motor Starters EM 300 EDS and
EM 300 ERS?
Motor starters EM 300 EDS/ERS
Motor starters EM 300 EDS and EM 300 ERS are electronic motor starters,
which can be used on the ET 200X distributed I/O device as expansion module.
Up to six motor starters EM 300 can be added to the basic module.
Characteristics
The motor starters EM 300 EDS/ERS:
• Are suitable for switching and protecting any three-phase loads up to 2.2 kW
with 400 V AC.
• Are available as either direct starters (EM 300 EDS) or reversing starters
(EM 300 ERS) with adjustment ranges from 0.6 to 2.18 A and 2.0 to 5.95 A
respectively.
• Can be equipped with a 24 V DC, max. 3 A, or 400 V AC, max. 0.5 A, or
500 V DC, max. 0.2 A braking contact as an option.
