Electrical Equipment Protection, Class I Relays for Std Applications - SPD

Description

Fanox Class B (Class I) Electrical Equipment Protection Relays for Standard Applications - SPD
The VP range of relays protect electrical equipment and installations against transient overvoltage that may arise in the electrical supply. Besides, the VP range can be classified
into 3 different types (C, B, B+C)
which provide the highest protection level in order to prevent damages in the electrical equipment and financial losses.
Relays on this listing are Class I according to IEC 61643-1
BENEFITS

·
Visual indication of a fault in the equipment.
·
High discharge capacity via "Spark gap" technology.
·
With thermal separation device.
·
Remote signaling of the protection status.
·
