Drives, switchgear, contactors, sensors, PLC and control spares, genuine and traceable, for plants where the supply voltage is not the rating.
Send the serial number of the unit, and a photograph of its nameplate with it. The serial number is what the part is ordered against; the nameplate settles which version of the machine it belongs to, because the same number can appear on more than one.
Part numbers are welcome where you have them. The quotation states the genuine part, its origin and its lead time.
Drives, contactors and switchgear are rated at a reference ambient temperature. Above it the equipment derates: the same unit delivers less continuous current, and expected service life falls. The derating is normal and it is not stated on the nameplate.
An unstable supply increases the duty further.
Switchgear and control equipment account for approximately fourteen percent of current supply, and they are the first category ordered by a plant returning to service after damage.
Rated current is stated at a reference ambient. The curve shows the permissible continuous current as the panel-room temperature rises above it.
