Cooling Types

Indramat EFC offers two cooling modes: natural cooling and enforced air cooling. For natural cooling, the temperature rise is kept within ≤ 0K75 for 1P 200 / 3P 380 VAC systems and 0K40 for 3P 200 VAC systems. On the other hand, enforced air cooling ensures greater cooling efficiency, maintaining a temperature rise of ≥ 1K50 for 1P 200 / 3P 380 VAC setups and ranging from 0K75 to 11K0 for 3P 200 VAC configurations. These cooling modes are crucial for regulating the internal temperature of the EFC units, ensuring optimal performance and reliability in various industrial applications.
