Blakley Electrics are the UK market leader in the supply of power distribution equipment and lighting systems for use on construction and civil engineering projects. All of our Construction Products are designed to be robust, long lasting and easy to install.
Blakley Electrics are proud and pleased to have won an Electrical Industry award for the second year running. This year we have won the award for our Mains Distribution Assembly equipped for temporary lighting management. The MDA is the only product of its type, offering installers and users a cost effective means of providing lighting control, thereby reducing emissions as well as running costs.
To meet the growing demand for energy conservation we introduced the 100A Mains Distribution Assembly with 8 no. TP outgoing ways, with 6 no. circuits automatically controlled from one programmable time clock. It is intended that the time clock controlled circuits supply transformers that feed non-emergency lighting circuits, whilst the 2 no. ways that are not controlled by the time clock feed transformers that are dedicated to Emergency Lighting Circuits.
The enclosure is suitable for wall mounting, providing protection to IP54. An optional stand is available. Enclosure finished by a pre-treatment and finishing system which is Type Tested to BS EN 60439-4 for corrosion protection in heavily polluted environments.
Fitted with a Merlin Gerin 8W TP pan assembly complete with 8 no. 32A TP Type “D” MCBs. 6 no. MCBs feed 40A TP contactors. The six contactors are controlled by a common programmable time clock. Five of the contactors have individual timers to prevent simultaneous closure, which averts the risk of the combined inrush current of the transformers from tripping the 100A MCCB that feeds the assembly.
The time clock has a 72 hour battery so that settings are not lost during short power outages.
An ON-OFF-AUTO switch is provided for manual control of the contactors and terminations are provided for connection to a remote override switch.
As an option, a version is available with remote wireless override enabling the contactors to be closed or opened at any time. The remote control transmitter can be up to 500 metres distance from the MDA.
The MDA is part of our GreenPower range of products, which are designed to provide reduced energy consumption.
