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.
