Direct driven centrifugal fans / Appendix / Accessories
Motor protection unit for three-phase current motors (standard motors) without thermal
contacts.
Design
Plastic casing in protection class IP55, permissible ambient temperature +40°C, 40Hz
up to 60Hz, frontal operation, for wall mounting. Motor protection unit for singlespeed,
non-variable speed three-phase current motors without thermal contacts.
Function
The motor protection units must be adjusted on site to the trigger current. If the
preset trigger current is exceeded, the device disconnects the motor from the mains
supply via a thermal overload release. Pressing the “on key” causes the unit to turn on
again.
All motor protection units EUM33 are also suitable for the protection of EExe-motors
(PTB-Prüfung Gesch-Nr. 3.35/386.3060). They must however be mounted outside of
explosion endangered areas, since they are not themselves designed with explosion
protection.
