Load interrupting
with 25kA asymmetric momentary and fault interrupting to 16kA
symmetrical.
Triad switches combine the total cost and
operating benefits of fuseless, electronically controlled,
resettable overcurrent protection with the safety and maintenance
benefits of a totally sealed, deadfront, SF6 insulated device.
In addition, Triad switches offer internal grounding of the
incoming and outgoing cables providing added safety and faster
operations. Two styles are available:
TRIAD SERIES 1
incorporates ground switches for the load break switch ways.
Two models are available:
Model VTVI:
Ratings through 38kV, 25kA asym. momentary, 12 or 16kA sym.
interrupting. Model VI vacuum interrupter mechanisms provide
single or three phase protection, field selectable. Front
access design available with all operating apparatus and cable
entrances in one compartment.
Model VTFI:
Ratings through 25kV, 25kA asym. momentary, 12kA sym interrupting.
Model FI vacuum interrupter mechanisms provide three phase
protection using a single internal three phase mechanism.
Front access design available with all operating apparatus
and cable entrances in one compartment.
TRIAD SERIES 2
incorporates ground switches for both the load break and fault
interrupter protected ways. Ratings available through 35kV,
25kA asym. momentary, 12 or 16kA sym. interrupting. Model
NI vacuum interrupter mechansim provides three phase protection.
Front/back design available with all operating apparatus in
the front and cable entrances in the back compartment.
