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

Terminal box position

Selectable options :

• 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 of PTC thermistors (3 pcs.) - for monitoring with PTC thermistor tripping or frequency inverter (standard from size 132)

1 set (3 pcs.) of temperature switches (bimetal opener) - for monitoring e.g. with motor protection relay

2 sets (6 pcs.) PTC thermistors - for pole-changing motors with separate winding

2 sets (6 pcs.) of temperature switches (bimetal opener) - for pole-changing motors with separate winding

The selection of one of these options is recommended when operating the motor on the frequency inverter, as the motor may overheat due to reduced speeds and the associated lower cooling capacity.
