Independent power supply with build-in power source,directly draws power from the incoming end to avoid the risk of protection function failure caused by external power supply failure.
● Overload protection
● Short circuit protection
● Isolation
● Controlling
● Used in residential building, non-residential building, industry, energy and infrastructure
Functions
● Types 2 surge arresters
● Handling energy from distant/ indirect lightning strikes or from switching operations
● Feature lower protection level (Up)
● Recommended at the incoming of installation for locations with no exposure to direct lightning impulses
