SDD DINsafe Surge Diverter - SDD1-50-275

SDD DINsafe Surge Diverter - SDD1-50-275

Distribution Board Surge Protection
Use DIN compliant SDD Surge Diverters for distribution boards or for point of entry protection in small industrial and domestic applications. Two layers of surge protection devices greatly improve the performance and reliability of the surge protection system.

All Mode Protection
Protection is provided for all combinations of lines ensuring the maximum level of protection is achieved at all times.

Thermal Sensing
Sustained overvoltages can cause components to overheat and degrade. Thermal sensing warns of this condition without disconnecting the protection.

LED Status Active Display
The LED display indicates phase status and normal operation when all LEDs are lit. An extinguished LED indicates a component failure or thermal overload, also initiating the optional external alarm.

Safe Metal Enclosure
Novaris power protection products are housed in safe, all metal enclosures. In the event of a prolonged overvoltage they will not catch fire or explode.
