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.

Bearing

Locating bearing n-side
Motors up to size 132 have floating bearings on both sides as standard. Optionally, a fixed bearing can be selected on the n-side to absorb axial forces.

Reinforced bearing
From size 160, a reinforced bearing with NU bearings can be used on the output side (d-side). This is recommended for increased lateral forces, such as those caused by belt drives. The bearing must be relubricated regularly, either manually or using a relubrication device. Open NU bearings are used.

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

Insulated bearing n-end for frequency converter operation
Measure to prevent bearing currents during operation on the frequency inverter possible from size 250.

Accesorios

Cubierta del ventilador con techo protector
Diseñada para evitar que caigan objetos extraños en el ventilador y para protegerlo contra la entrada de agua. Se utiliza para motores con posición de instalación vertical.

Ventilador de refrigeración forzada
Para uso con accionamientos de velocidad controlada. El ventilador de refrigeración forzada instalado en lugar de la cubierta del ventilador estándar garantiza una refrigeración suficiente incluso a velocidades "muy bajas". Tensiones de conexión múltiples: 230V/50Hz/1~ y 400V/50Hz/3~, clase de protección IP55
Atención: ¡la longitud total del motor aumenta!

Calefacción de parada
Evita la condensación incluso en condiciones climáticas extremas
Posible a partir del tamaño 80. Tensión de conexión: 230V/50Hz
