Ingress protection
The WE series comes standard with protection grade IP55, adaptable to IP56, IP65, IP66, and other protection levels based on specific customer requirements.
The robust shell protection is designed to prevent accidental electric shock, restrict access to live or rotating parts, block solid foreign bodies, and safeguard against harmful water and oil ingress. The protection codes and their meanings are detailed as follows:

Code	Meaning	First numeral	Meaning	Second numeral	Meaning
IP	Level of protection	5	Dust prevention	5	Protected against water spray (12.5L/min @ 0.3 bar)
		6	Dust tight	6	Protected against water jets or heavy seas (100L/min @ 1.0 bar)

Cooling method

The WE series features F-class insulation, with temperature rise assessed to B-class standards. Optionally, nano-insulating impregnation resin can be employed to extend operational life in complex power supply and environmental conditions.
To ensure reliable operation, the motor employs insulating materials between live parts and the shell or amongst live parts. The longevity of these materials directly correlates with insulation level and operating temperature. During operation, energy losses cause temperature rise; however, the motor's insulation grade and temperature rise limits, as measured by the resistance method, comply with the outlined table requirements. Within these limits, the motor is designed to function optimally.
