Tab.3: Overview of the technical data of the protection devices for screw compressors (in the case of differing requirements/operating condi-
tions, consultation with BITZER is recommended)
①: The SE-E2 has a relay with gold contacts. After a
first operation at AC/DC>36V or >50mA,the min-
imum switching voltage is AC/DC>24V and the min-
imum continuous current is >20mA.
②: Suitable for operation with soft starter at a ramp
time shorter than 1s.
③: For operation with soft starter: 200..690VAC,
±10%, 50/60HzAC
EMC: All protection devices comply with the EU EMC
directives 2014/30/EU and 2004/108/EC.
