General technical data

Interference immunity

Meets EN 61800-3; 2nd environment

Interference emission

Limit value class C2 according to EN 61800‑3

Ambient temperature ϑA

0 – 45 °C without derating  

Type of cooling

Increased air cooling thanks to an installed, temperature-controlled fan or convection cooling

Short-circuit current

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

Nominal data

The nominal data refers to a line voltage of 3 × AC 400 V; project planning is required if the line voltage deviates.

Degree of protection

IP20 in accordance with EN 60529

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.
