Refurbishment
We supply refurbished Masterpact M ACBs in all frame sizes, both 3 and 4 pole. Please contact us to find out current stock levels and prices.
The refurbished ACBs are available with electronic protection units that come standard with communications capability (24V DC power supply required).
All ACBs have been refurbished to a high standard, all operating coils including the flux coil are replaced with new units and a new motor charge unit is also fitted.
Where necessary the auxiliary pick up contact pins are replaced with new items, the ACB is then inspected and undergoes rigorous testing.
We can also supply the bare ACB with no electrical operators or protection unit should this be required. (Price on Application)

Partial discharge monitoring
PS Electrical offer a regular monitoring service, checking high-voltage electrical equipment for early warning signs of partial discharge, which is generally accepted as the predominate cause of long term degradation and eventual failure of electrical insulation.

Thermal Imaging
Using especially high-end, ultra-sensitive equipment, we undertake thermal imaging surveys to pinpoint latent defects before they lead to a breakdown and loss of service, and to provide full risk and method statements. For more information, please visit our main site here.
