Polarized High-Voltage Contactors. Polarized contactor relays have optimized magnetic blowouts that maximize arc quenching. Permanent magnets on the sides of the contact chamber create magnetic fields that bend the arc. By causing the arc to travel a longer distance, resistance is increased, and the arc extinguishes faster.
