Can I use a softstarter for an ATEX motor?

ABB’s softstarters PSR, PSE and PSTX can be used to start ATEX classified
motors in Ex environments if the following considerations are taken into
account:

– The softstarter has to be placed outside the Ex area. Either in another
location or inside an ATEX approved panel.
– A separate ATEX approved overload relay from ABB has to be used
together with a line contactor. This overload relay will replace the built-in ATEX
EOL in the softstarter and has an ATEX approved tripping curve.
– Select softstarter according to normal or heavy-duty start depending on
application and line contactor and overload relay with type 2 coordination.
