- Electrical Tests

All WAGO products meet requirements for the following electrical tests:
• Temperature-Rise Test per IEC/EN 61984, IEC/EN 60947-7-1, IEC/EN 60998-1

The Temperature-Rise Test examines the clamping point, including the surrounding insulation, at rated current, over-current and
short-circuit current levels.
Unless otherwise specified in the related equipment specification, e.g., by specifying the nominal currents of the equipment, termi-
nal blocks and connectors are tested with current loads as specified in the respective construction specification.

For rail-mounted terminal blocks complying with IEC 60947-7-1/EN 60947-7-1/VDE 0611, Part 1, or terminal blocks complying
with IEC 60998-1/EN 60998-1/ VDE 0613, Part 1, the temperature rise must not exceed 45 Kelvin.

Connectors must withstand the upper and lower values of the temperature range as specified in the detailed specification or man-
ufacturer‘s specification.
The sum of the ambient temperature and the temperature rise of a connector shall not exceed the upper temperature limit.
