Voltage

230/400V/D/Y, 50Hz (standard for motors up to 3.0kW)
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 4.0kW)
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 winding is designed for motors up to 4.0kW in 290/500V/D/Y, 50Hz as standard and from 5.5kW in 500/865V/D/Y 50Hz.

Protection class

IP code for the degree of protection in accordance with DIN EN 60529, 60034-5,
First code number: Protection against ingress of foreign bodies
Second code number: Protection against ingress of water with harmful effects

Selectable options:

IP55 - dust-protected, protection against water jets (standard)
IP56 - dustproof, protection against strong water jets
IP65 - dust-tight, protection against water jets
IP66 - dust-tight, protection against powerful water jets

Terminal box position

Up to size 132, the terminal box position can be varied by screwing the feet over (top, right or left)

Selectable options from size 160:

• top (standard)
• right
• left

The terminal box position is defined by looking at the output shaft side of the motor.

Example "Terminal box right"

Motor protection

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

• 1 set (3 pcs.) of PTC thermistors - for monitoring with PTC thermistor tripping device or
  Frequency inverter (standard)
• 1 set (3 pcs.) of temperature switches (bimetal NC contacts) - for monitoring e.g. with
  motor protection relay

Current carrying capacity
Rated current (AC: Cos Phi = 1.0): 250VAC / 2.5A
500VAC / 0.75A
Rated current (AC: Cos Phi = 0.6): 250VAC / 1.60A
500VAC / 0.5A

• Resistance temperature sensor PT100 - PT100 is a platinum resistance thermometer, which at
  0°C has a defined resistance value of 100Ohm and is used for precise temperature measurement.
• Resistance temperature sensor PT1000 - PT100 is a platinum resistance thermometer that has a defined resistance value of
  0°C has a defined resistance value of 1000 ohms and is used for precise temperature measurement.

The 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.

Rodamiento

Rodamiento fijo lado n
Los motores hasta el tamaño 132 tienen cojinetes flotantes en ambos lados como estándar. Opcionalmente, puede seleccionarse un rodamiento fijo en el lado n para absorber las fuerzas axiales.

Cojinetereforzado
A partir del tamaño 160, se puede utilizar un cojinete reforzado con rodamientos NU en el lado de salida (lado d). Se recomienda para fuerzas laterales elevadas, como las causadas por transmisiones por correa. El rodamiento debe relubricarse regularmente, ya sea manualmente o mediante un dispositivo de relubricación. Se utilizan rodamientos NU abiertos.

Dispositivo de reengrase lado d y lado n
Posible a partir del tamaño 160, para una relubricación sencilla de los rodamientos del motor. El dispositivo de reengrase es estándar a partir del tamaño 315.

Rodamiento aislado lado n para funcionamiento con convertidor de frecuencia
Medida para evitar corrientes en los rodamientos durante el funcionamiento en el convertidor de frecuencia, posible a partir del tamaño 250.

Colour scheme

Colour shade

Standard colour RAL7024 - Graphite grey

Attachments and accessories

Fan cover with protective roof
Designed to prevent foreign objects from falling into the fan and to protect against water ingress. Used for motors with vertical installation position.

Forced cooling fan
For use with speed-controlled drives. The forced cooling fan installed in place of the standard fan cowl ensures sufficient cooling even at "very low" speeds. Multi-connection voltages: 230V/50Hz/1~ and 400V/50Hz/3~, protection class IP55
Attention - overall length of the motor increases!

Standstill heating
Prevents condensation even under extreme climatic conditions
Possible from size 80. Connection voltage: 230V/50Hz
