This document describes the conditions and requirements for exporting frequency inverters from Eaton Moeller in Europe to the North American market. Frequency inverters are electrical devices used for controlling the speed of AC motors.
The document provides an overview of the North American market for frequency converters, describing the harmonisation of standards, trade agreements and the differences between European and NAFTA‑zone regulations. It outlines the key safety norms (IEC 61800‑5‑1, IEC 61800‑3, UL508C) and the responsibilities of manufacturers and end‑users.
Further sections detail the role of UL and CSA certification, the short‑circuit current rating (SCCR) requirements for industrial control panels, and the specific rating tables for power and current of Eaton’s M‑Max and H‑Max series. Practical guidance is given for selecting over‑current protection and achieving the required SCCR levels. This manual is written in German.
| Rated power range | 1.5‑50 HP (1.1‑37.3 kW) |
|---|---|
| Rated current | 5 000 A |
| Short‑circuit test current limit | Devices rated 600 V or less |
No, UL is not a law; it is a voluntary certification from an independent testing laboratory.
The standard SCCR value is 5 kA for converters up to 50 HP (37.3 kW).
Yes, the document states that UL is not mandatory; compliance with IEC standards is sufficient for many applications.
