Fire rated switch disconnectors Switch disconnectors Ventilation and smoke extraction systems aim to help safe working conditions on building evacuation and fire rescue operations, diminishing roof temperatures and delaying lateral fire expansion in order to permit an effective fight against fire expansion. Standard EN- 12101-3:2015 applies to Smoke and heat control systems detailing on part 3 specifications for powered smoke and heat exhaust fans. In order to guarantee installation safety under emergency conditions all ventilation system components must comply with this...

Fire rated switch disconnectors Tests The development of products rated to provide fire resistance in order to guarantee electrical functional integrity under extreme circumstances, does require the employment of specialist laboratories capable to reproduce, on a controlled manner, similar conditions to those that take place when a fire occurs. The recognized* AFITI laboratory has facilities that allow constant pressure and temperature monitoring on the testing area thus ensuring that the temperature curve is replicated as established by the standard. *ENAC Spanish recognized part of ILAC...

Switch disconnectors The range of F300 and F400 switch disconnectors share the aluminium enclosures that offer a high IP and IK rating. The F300 range is limited at 40A and the F400 is limited to 125A when using aluminium enclosures. F400 higher ratings (160-250A) use lightweight sheet steel enclosures for easy handling and installation. All the range follows a surface treatment consisting of a epoxy polyester powder coating by electrostatic projection and high temperature oven drying that provides excellent protection against chemical agents.

low voltage electrical manufacturer Fire rated switch disconnectors fA PRDTEC F300 Classification F300 switches are based on advanced polyether polymers that are widely used on the motor and aeronautic industry due to its high temperature resistance combined with excellent wear, chemical and hydrolytic behaviour.

Switch disconnectorsF400 Classification Standard references The stringent requirements on class F400 under fire conditions require the use of special composite materials that must combine good resistance to extreme temperatures while maintaining electrical characteristics requirements under IEC 947-3 when operating on normal conditions. To guarantee insulation characteristics we need the use of an specific contact block dedicated to F400 classified switches. Mechanical components also must be modified in order to pass product testing sequence which requires a minimum functioning period of...

low voltage electrical manufacturer Fire rated switch disconnectors Fire rated F600 Constructing F600 switch disconnectors does require the use of very special materials able to overcome the extreme conditions under this category. The enclosure is on cold-laminated steel resistant to 600°C temperature. Developing a particular mechanical block for high temperature has also improved switch behaviour when shortcircuit occurs while keeping the electrical characteristics when operating under normal conditions.
