CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The rated current per pole at 40°C ambient is 10 to 32 A, as per IEC 60947-7-1. However, this is a reference range; the exact value depends on the specific model and application. Always verify with the manufacturer's datasheet.
Yes, the assembly is designed to handle various circuit types, including power distribution, sensor signals, and control circuits. The modular design allows grouping of related circuits, but ensure that the rated voltage and current for each circuit are within the assembly's specifications.
The degree of protection is IP20 for open assemblies and IP65 when installed in an appropriate enclosure, according to IEC 60529. This means the assembly is protected against solid objects larger than 12.5 mm (IP20) and against dust and water jets (IP65) when enclosed.
The assembly references IEC 60947-7-1 for terminal blocks, IEC 60947-1 for general low-voltage switchgear, IEC 60529 for degrees of protection, and UL 94 for flammability. These standards are procurement references; compliance must be confirmed with the manufacturer for the specific product.
