SPDs for Low Voltage Power Supply Systems

DEHN’s popular Red/Line and Yellow/Line series SPDs are the perfect protection solution covering all applications from Power systems to Telecom / IT requirements. The SPDs (compliant with IEC / EN 61643-21) have a modular design concept to achieve ease of installation and cost optimization.
Features
- Modular multipole combined Lightning Current and Surge Arrestors
- Available in Class I, Class II, Class I+II, Class III
- With discharge current upto 100 kA
- With end-of-life changeover contact option
- Available in cartridge and fixed types
Red/Line Series
(For Power Supply Systems)
- Minimized risk of damage caused by impulse currents
- Short circuit interruption with active arc extinction ensures safe electrical isolation and reduced risk of fire in photovoltaic systems
- Ensures full energy coordination in Class-1 SPDS hence the lightning impulse current does not overload downstream SPDs

Yellow/Line Series
(For IT Systems)
- Maximum protection and compatibility with different interfaces
- Variable protection for 1 to 20 pairs in LSA Systems of 2/10 type
- Corrosion-resistant stainless steel SPDs to be screwed onto field devices
