Fairford PFE-06, 9Amp, 4kW
Fairford PFE-06, 9Amp, 4kW three-phase motor soft starter
The PFE soft start is designed for trip class 5 (light industrial) applications. It can be used on trip class 10 (medium industrial) applications if it is over sized by one or two kW ratings (i.e. 11kW - PFE for a 7.5kW - motor). The PFE should not be used on heavy industrial applications.
Please note: Undersizing the PFE to the application can potentially cause damage to the PFE.

Optional cooling fan increases number of starts per hour.
A external motor thermal overload device is required for the PFE soft starters.
The PFE has an internal bypass relay so no external bypass relay required.
A +24VDC power supply is required for the PFE control circuitry.
The DRA18-24 (APSU005) is a suitable power supply. This can be used for up to 3 x PFE softstarts.
DRA18-24: 100 - 240VAC single phase input, 24VDC 18W output.
If a +24VDC power supply with a 400V 3 phase input is required, the WRA120-24 (APSU007) is a suitable power supply.
WRA120-24: 400 - 500VAC 3 phase input, 24VDC 120W output.
The Enable & Start/Stop control logic is 24VDC.
