Manufacturer profiles associated with Terminal Blocks/Connectors.
Manufacturer listings support early research and capability understanding. They are not certification, ranking, or transaction guarantees.
A practical evidence checklist for RFQ preparation and supplier evaluation.
CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
The rated voltage is up to 300 V continuous, and the rated current ranges from 10 to 32 A depending on wire cross-section and ambient temperature, per IEC 60947-7-1. Always verify the specific model's ratings with the manufacturer.
They accept solid or stranded wires with cross-sections from 0.2 to 4 mm². Ensure the wire is properly stripped and inserted according to the terminal type (screw or spring clamp).
The continuous operating temperature range is -40°C to 105°C. For applications outside this range, consult the manufacturer for suitability.
No, they have a degree of protection of IP20, which means they are finger-safe but not protected against dust or water. They are intended for indoor use within control cabinets or enclosures.
