Standards and product approvals

Applicable regulations, standards, and approvals
Below is a list of extracts from the most important standards and approvals of the 3RT and
3RH contactors.
Note
Depending on meaning, some standards and approvals are applied only to specific product
variants and are restricted to these. For example, the IEC 60077-2 standard is taken into
account only for contactors for rail applications but not for standard contactors.
