Topper® series group-operated switches

Why Topper® series group-operated medium-voltage switches?

Topper series group-operated medium-voltage switches provide efficient three-phase switching for electrical distribution systems.

These switches are available with voltage ratings from 15 to 38 kV, continuous current up to 1,200 A and lightning impulse (BIL) up to 200 kV. Address challenges in installations where mounting clearances are limited with our compact style switches.

The Topper series comes fully assembled and factory adjusted on either a steel or aluminum base, with several mounting styles including pole-top, crossarm, phase-over-phase, upright and vertical styles.
