Protection modules for scroll and reciprocating compressors SE-B1/SE-B2/SE-B3
Temperature monitoring
The SE-B1/SE-B2/SE-B3 opens the relay contact in
the control circuit and locks out immediately if the
allowable temperatures for motor or discharge gas
(optional PTC sensor) are exceeded.
Reset
Interrupt supply voltage (L/N) for at least 5
seconds.
All Bitzer reciprocating and scroll compressors of
the ESH7 and ESH9 series have as standard equip-
ment the motor protection devices SE-B1, SE-B2 or
SE-B3 (Signal Evaluation - Basic).
