Protection against electric shock

Blakley Electrics manufacture a range of composite protection assemblies designed for installation in school science laboratories and similar locations, where the proximity of children, water and mains voltage electricity creates an extremely hazardous environment requiring the highest level of protection against electric shock.

SSUs provide a threefold level of protection:

  1. RCD sensitivity of 1.25 mA or 5 mA
  2. Shock current restricted to 10 mA
  3. Reduced line to earth shock voltage of 115V

Enclosures are of robust construction to ensure longevity and to minimise vibration and noise and are ventilated to assist with cooling and fine mesh is fitted behind the louvres to prevent the insertion of litter and other debris. Floor standing enclosures incorporate fixing holes to enable them to be secured to walls.
