Counterfeit goods are becoming an increasing problem in the electrical industry. Imitators are flooding the market with products that appear confusingly similar to the original brands, with fatal consequences in terms of fire protection. Only a high-quality electrical product can guarantee a defined period in which the electricity flow can be sustained valuable minutes which can prove essential for rescuing fleeing people. Higher material quality, better combustion behaviour and comprehensively tested features ensure this extra time. As a brand manufacturer, Spelsberg offers the safety of significant investments in research and technology, and strict national and international test procedures. And the reputation of a proven brand name. 4 Safety from a strong brand.

Maintained function of the electrical systems is assured if no short-circuit occurs during a fire and if the current flow is not interrupted in important safety systems. This means the power supply to the escape and rescue routes is maintained in the event of external exposure to fire. Maintaining electrical function is crucial at all locations where large numbers of people tend to circulate, such as schools, hospitals, government agencies, industrial plants or shopping centres. Since the risk of fire can never be excluded fully in spite of the most stringent safety precautions, the requirements in terms of material and installation can never be high enough. The Spelsberg portfolio offers planners, operators and installers optimum quality when it comes to the vital issue of maintaining functionality. Maintaining electrical integrity. A life-saving concept. 5

Fire safety regulations for electrical installations are strictly prescribed in the areas of construction and electrical technology so as to ensure that nobody is insured as a result of fire and smoke. The critical factor is maintaining the function of electrical cable installations in accordance with DIN 4102 Part 12. This standard stipulates that only complete cable installations including all components, such as ducting system, cables and dowels, can be inspected and approved for function maintenance. Spelsberg is the common element here. All fire protection products offer proven function maintenance in the E30 to E90 classes to meet the most stringent requirements for residential and office construction to major projects for industry and transport. 6 Clear standard: DIN 4102 Part 12

How long electrical integrity can be maintained is specified in minutes by the E30 to E90 classes. When a fire breaks out, the first 30 minutes are critical for evacuating a building. For the fire brigade, maintained function of 90 minutes is essential for fighting the fire. E30: Assures maintained electrical function for at least 30 minutes E90: Assures maintained electrical function for at least 90 minutes Fire alarm systems Acoustic systems Emergency lighting Lifts with evacuation circuit Pressure-boosting systems for supply of water for firefighting Smoke and heat exhaust ventilators Firefighting lifts Emergency power supply Valuable minutes: E30 to E90 7

The oil-fired oven at the materials testing institute in Dresden reaches temperatures of more than 980 degrees Celsius. Flames strike against the WKE AK small-scale distributor from Spelsberg. For the first time, the entire installation is being tested under load in accordance with the electrical engineering and construction regulations, not only the enclosures, cables and switchgear. The focal point of these tests is the fire and moisture resistance of the distributors. A switching operation is performed after more than 80 minutes of extreme testing. The result: Despite fire and condensation, the electrical installation withstands switching the electricity off and then on again without sustaining any damage and with full functionality. By passing this endurance test in 2010, the Spelsberg WKE AK small-scale distributors successfully united the specialised fields of fire protection, building law and electrical technology. The two-layered housing reinforced with fireproof panels reliably protects the installed electrical components inside against fire from outside and inside, so the distributor satisfies the strict requirements for service in escape and rescue routes. The extremely rugged WKE AK series of junction boxes has been tested and approved according to DIN EN 60439-1, making Spelsberg the first company to receive a VDE certificate for a fireproof, freely configurable small distributor.
