Overview

The ABB MVI3-30-20 is a molded vacuum interrupter designed for three-phase applications requiring external control. Rated for 30A continuous current, this interrupter is compatible with ganged three-phase MVI mechanisms and includes a 20-foot control cable for flexible installation. The device ensures reliable interruption of current in medium-voltage switchgear, protecting downstream equipment from overloads and faults. Its molded design provides environmental resistance, making it suitable for indoor and outdoor installations where dust, moisture, or contaminants are present. The three-phase trip-only functionality simplifies coordination in ganged mechanisms, reducing wiring complexity. With ABB’s proven vacuum interrupter technology, this unit delivers consistent performance in industrial, commercial, and utility applications. The included cable eliminates the need for field-terminated wiring, streamlining deployment. Ideal for retrofits or new installations in switchgear, motor control centers, or distribution panels where space and reliability are critical.
