General conditions for use

Pollution class

2 according to IEC 60664‑1

Overvoltage category

III according to IEC 60664-1

Installation altitude

h

Up to h ≤ 1000 m without restrictions.

The following restrictions apply to altitudes > 1000 m:

• From 1000 m to max. 3800 m: I_N reduction by 1% per 100 m
• From 2000 m to max. 3800 m: To maintain protective separation and the air gaps and creepage distances in accordance with EN 61800‑5‑1, you have to connect an overvoltage protection device in order to reduce the overvoltages from category III to category II.

Proof of mechanical strength

Class 3M11 and class 5M2 according to DIN EN IEC 60721-3-3/-5
