: 95 kV crest

: 34 kV rms

: 11 kV rms

SWITCHING

1-phase and 3-phase circuits 8.3 kV phase-to-ground, 14.4 kV maximum across the open contacts.

: 10 loadmake/loadbreak operations at 200 A with 70-80% lagging power factor.

FAULT CLOSURE One fault-close operation at 8.3 kV phase-to-ground, or 14.4 kV phase-to-phase; 10,000 A rms symmetrical, 10 cycles, (0. 17 seconds).

Features • Red snuffer nose for 15kV Class product recognition. • Yellow seating indicator ring molded in for positive indication that mating product is fully seated.

PRODUCTION TESTS

100% factory test for partial discharge and either AC HI-POT (34 kV for 60 seconds) or impulse (BIL) (95 kV 1.2 x 50 µ sec.\wave).
