GB1984 JB3855 IEC62271-100 2001
The vacuum circuit-brerkers of type ZN85-40.5(3AV3) are intended for indoor installation in air-insulated switchgear.
(
The vacuum circuit-breaker complies with the following specifications: GB1984,JB3855, IEC62771-100:2001. The
vacuum circuit-breakers have particular advantages for use in systems where the switching frequency in the operating
current range is high, and/or where a certain number of short-circuit breaking operations, and the VCB are prepared
for auto-reclosing operations, and have exceptionally high operating reliability and long life. The vacuum circuit-
breakers of type ZN85 can be supplied both as individual units for stationary mounting and mounted on trucks.1
