NFPA79 compatible SPD (surge absorber) for equipment
Otowa Electric Industry Co., Ltd.
About This Product
■Features
1. UL 1449 Listing certified/NFPA79 compliant
Complies with NFPA79 surge protection requirements for industrial machinery exported to the United States, and can be installed on industrial machinery exported to the United States.
NFPA79: Starting with the 2018 edition, it describes surge protection for industrial machinery used in the United States. If the safety-related circuits of industrial machinery are not sufficiently protected from overvoltage, installation of this SPD with UL Listing certification is required.
2.Built-in disconnection device/with SPD function display
・Built-in disconnection device when ZnO element deteriorates to prevent SPD from smoking or catching fire
・With SPD function display of disconnection mechanism
3.Compact and space saving possible
・An integrated line-to-ground and line-to-ground type that protects against induced lightning surges between lines and ground.
・Achieved miniaturization by adopting multi-terminal type element, same dimensions from 200V to 500V
4.Reliable lightning surge resistance
・With maximum discharge current of 5kA (8/20μs), it is not easily damaged by large lightning surges.
・Withstands 1,000A 500 lightning surges, long lifespan
5.Compatible with safety standards
・EN 61643-11 TÜV certified (TÜV SÜD Japan)
・IEC 61643-11
・UL standard (UL 1449 Listing certified) /CSA standard (C22. 2 No. 269) certified ・Uses flame retardant material (UL V-0)
6. Compatible with RoHS regulated substances
