Data Show at EXCEL London


Masterpact Center of Excellence ​recently had a stand at the Data and cloud show at the Excel Centre in London at which we were able to demonstrate our new Amp Safe Pro Plus protection unit for the Schneider/Merlin Gerin Masterpact M Air Circuit Breaker.

In addition to the standard protection settings that emulate from the STR 18M, STR28D ,STR38S ,STR58U and the STR68U, the plus also has full power metering capabilities as well as Modbus communications.
The Plus was fitted to our demonstration breaker along with the new operating coils and conversion system and also had the new generation Motor Charge assembly as well as new CT’s ,main poles and auxiliary contacts.
The demonstration created a great deal of interest from both Switchgear manufacturers looking to support existing switchgear and from both large and small end users who have Masterpact M currently in service , the life extension program built around the Masterpact M offers by far the most cost effective solution available today.

PS Electrical Services Ltd ,which is the parent company also demonstrated the services available for Data Centre Switchgear maintenance and these included thermal imaging for non intrusive surveys as well as Partial Discharge testing for HV distribution systems.

PS Electrical Services engineering staff have the capability to refurbish your existing Masterpact M product as well as being experienced in standard manufacturers maintenance schedules in all leading brands of switchgear.
