Description
The ribbed cast iron frame of the enclosed design has protection degree IP55, IP56, IP65 or IP66. Cooling is IC410 without a fan, IC411 self-ventilated, IC416 with an independent fan, or IC418 cooled by the airflow of the driven machine. The number of poles is 2, 4, 6, 8 or 10, supplied from the grid or a frequency converter. Insulation is 155 (F) used to 130 (B) or 180 (H) used to 155 (F), mounting B3, B35, B5, V1, V5, V6 and others, with CE marking. For enclosed IP55 motors there is a detailed operating manual, including requirements for machines for explosive zones 1 and 2. The plant has belonged to a larger group since 2011. Under the designation KA2 the site also shows a high-voltage motor KA2454X-EJ01E-Z of 220 kW, 6000 V and 596 rpm, and it does not belong to this low-voltage item.
How to choose
Shaft height, cooling method and voltage up to 1100 V decide the choice. For pumps, fans, compressors, conveyors, mills and mixers in oil and gas, chemical and metallurgical industries, power generation and water management, self-ventilation IC411 is suitable, and for operation from a frequency converter at low speeds an independent fan IC416 is better. The series replaces large low-voltage motors of 0.4–0.69 kV of the series 5AM, AIR 355 and 4AM.

FAQ
What power and voltage range do KA2 motors have?
375–1320 kW at 200–1100 V from the grid or a frequency converter.
What are Transnorm frame sizes?
These are intermediate frame sizes between standard IEC motors and large machines. For KA2 the shaft height is 315–560.
What cooling schemes and protection degrees does KA2 have?
IC410, IC411, IC416 and IC418, and protection IP55, IP56, IP65 or IP66.
What efficiency class does KA2 have?
IE3 for the low-voltage series of 375–1320 kW.
Does the high-voltage KA2454X-EJ01E-Z belong to this series?
No. This motor of 220 kW, 6000 V and 596 rpm only has a similar designation, and the low-voltage KA2 are described separately.
