CNFX does not score or rank suppliers. Buyers must verify all claims and documents with the legal manufacturer before ordering.
A motor starter starts and stops an electric motor safely and reliably, and protects it from overload and phase failure by disconnecting the motor from the power supply when excessive current is detected.
The rated power range is 0.75–250 kW, and the rated voltage range is AC 220–690 V, according to IEC 60947-4-1. These are reference ranges; confirm the specific model's ratings with the manufacturer.
The overload relay continuously monitors the motor current. If the current exceeds a preset threshold for a sustained period, the relay trips, de-energizing the contactor coil and disconnecting the motor from the power supply, preventing damage from overload or phase failure.
The product references IEC 60947-4-1 and IEC 60947-1 for electrical characteristics, and IEC 60529 for degree of protection. These standards are procurement references; actual compliance must be verified with the manufacturer.
