Rated voltage

230/400V/D/Y, 50Hz
(standard for motors up to 2.2kW) Possible applications: In star connection (Y) directly on 400V mains, in delta connection (D) on frequency inverters with output voltage 230V/3~ or on frequency inverters with output voltage 400V/3~ and operation with 87Hz characteristic curve

400/690V/D/Y, 50Hz
(standard for motors from 3.0kW) Possible applications: In delta connection directly on the 400V mains, and on frequency inverters with output voltage 400V/3~, star-delta starting with switches or contactors

500V, 50Hz
The standard winding for motors up to 2.2kW is in 290/500V/D/Y, 50Hz and from 3kW in 500/865V/D/Y 50Hz.

Protection class

• IP55 - dustproof, protection against water jets (standard)
• IP66 - dustproof, protection against strong jets of water

Motor protection

The following options are available for monitoring the winding temperature of the motor:

1 set (3 pcs.) PTC thermistors - for monitoring with PTC thermistor tripping or frequency inverter (from size 160 standard version without surcharge)

1 set (3 pcs.) of temperature switches (bimetal opener)- for monitoring, e.g. with motor protection relayThe selection of one of these options is recommended when operating the motor on the frequency inverter, as the motor may overheat at reduced speeds and the associated lower cooling capacity.

Shaft / Bearing

Relubrication device d- and n-side
possible from size 160, for simple relubrication of the motor bearings. From size 315, the
relubrication device is standard.

Insulated bearing n-end for VFD operation
Measure to prevent bearing stresses during operation on the frequency inverter
possible from size 225

Fixed bearing n-end
Motors up to size 132 have floating bearings on both sides as standard. Optionally, a locating bearing on the n-side can be
can be selected to support axial forces

Coloring

Color shade

Standard shade RAL 7030 - stone gray

Miscellaneous

Fan guard with protective roof
Designed to prevent foreign bodies from falling into the fan and to protect against water ingress, for use with motors with vertical installation position. For use with motors with vertical installation position.

External fan Wistro IL
For use with speed-controlled drives. The forced cooling fan installed in place of the standard fan cover ensures
sufficient cooling even at "very low" speeds.
Multi-connection voltages: 230V/50Hz/1~ and 400V/50Hz/3~, protection class IP66
Attention - total length of the motor increases!

Flexelec RSV standstill heater
Prevents condensation even under extreme climatic conditions
Possible from size 132. Supply voltage: 230V/50Hz

UL/CSA version
Design with combined approval/certificate that complies with both US and Canadian regulations.
regulations. The motors are stamped as follows: 275/480V, 60Hz or 480/830V, 60Hz, voltage/frequency tolerance range A
