General technical data

Interference immunity

Meets EN 61800-3; 2. Environment

Interference emission

Limit value class C2 according to EN 61800‑3.

The interference suppression level can be improved using appropriate measures.

Refer to chapter EMC-compliant installation according to EN 61800-3 for further information.

Ambient temperature ϑamb

-10 – 40 °C without derating

40 – 55 °C with derating

For further information, refer to chapter "Project planning" > "Selection of an inverter" > Power reducing factors.

Type of cooling

Natural convection:

  • MCC91A-0010 – 0025-5.3..
  • MCC91A-0017 – 0034-2.1..

Forced convection through built-in temperature-dependent fan (ON – at heat sink temperature 44 °C / OFF – at heat sink temperature 40 °C):

  • MCC91A-0032-5.3.. – MCC91A-0240-5.3..
  • MCC91A-0042-2.1.. – MCC91A-0093-2.1..

Short-circuit current

The uninfluenced short-circuit current according to EN 61800‑5‑1 is 65 kA.

Degree of protection

IP20 in accordance with EN 60529, only with power connectors plugged in for grid and motor

Pollution class

2 in accordance with IEC 60664‑1

Overvoltage category

III in accordance with IEC 60664-1

Installation altitude above sea level:

No restrictions apply to altitudes ≤ 1000 m.

The following restrictions apply to altitudes > 1000 m:

  • From 1000 m to max. 3800 m: IN reduction by 1% per 100 m
  • From 2000 m to max. 3800 m: To maintain protective separation and the air gaps and creepage distances according to EN 61800‑5‑1, an overvoltage protection device must be connected upstream to reduce the overvoltages from category III to category II.
