Available in NEMA1/2 and NEMA 3R configurations, 380–600 V dV Sentry™ helps protect AC motors from destructive effects of extended lead voltages that can damage VFDs, cables, and motors. Triple Defense Core technology offers protection against peak voltage, high rise times, and common mode voltage reduction. Ability to reduce common mode voltage by >50% reduces damage to motor bearings and motor insulation as well as unexpected ground fault trips and erratic behavior of VFDs and PLCs.
