Blakley Electrics Safe Supply Units (SSUs) have long been specified for use in school laboratories, where the close proximity of water and electricity present a major electrical hazard. 

SSUs provide the highest level of protection against electric shock and incorporate a 1:1 ratio transformer, 1.25mA or 5mA RCD protection and a current limiting resistor which restricts the maximum level of earth leakage to 10mA at all times. Models are also available with integral DP MCB distribution arrangements, Remote Trip Facility for connection to Emergency Stop Buttons and Key Switch contol. A FAQ sheet on SSUs is located in the Technical Data Sheets section of the website, which can be accessed by clicking the Dowloads tab above.

Other products, such as Variable Laboratory Supply Units, Transformers and High Sensitivity RCDs are also widely installed in Laboratories, Craft Workshops and Plant Rooms. Details of many products are on the website and information on the range is outlined in our Education brochure, which can be opened from the link below. If you cannot find the product you require, contact our Customer Service Centres, who will be pleased to be of assistance.
