Fanox Class B+C (Class I+II) Electrical Equipment Protection Relays for Standard Applications - SPD
The VP range of relays protect electrical equipment and installations against transient over-voltage 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+II according to IEC 61643-1
BENEFITS
· Compact equipment for all distribution systems.
· High discharge capacity via "Spark gap" technology.
· With thermal separation device.
· Visual indication of a fault in the equipment.
· Remote signaling of the protection status.
· Plug-in protection modules which facilitate maintenance
· THREE (3) YEAR WARRANTY
