Overview

The ABB MVI3-80MAX is a three-phase molded vacuum interrupter designed for medium-voltage switchgear applications up to 38 kV. Rated for 25 kA interrupting current, this interrupter provides reliable fault interruption in power distribution systems where high fault currents and voltage levels demand robust performance. The MVI3 series is engineered for compatibility with ABB’s external control systems, offering enhanced flexibility in trip coordination and protection schemes. Key features include an external 80 control interface with selectable single-phase or three-phase trip functionality, allowing operators to configure protection strategies based on system requirements. The molded vacuum design ensures compact form factor and long service life, minimizing maintenance while maximizing reliability in critical applications such as utility substations, industrial power plants, and commercial distribution networks. The MVI3-80MAX is part of ABB’s Installation Products portfolio, a trusted brand in electrical infrastructure solutions. With a proven track record in medium-voltage switchgear, this interrupter is ideal for new installations or retrofits where space constraints and performance demands are high. Its 38 kV voltage rating and 25 kA interrupting capacity make it suitable for applications requiring compliance with ANSI/IEEE C37.04 and IEC 62271 standards. For engineers specifying medium-voltage protection equipment, the MVI3-80MAX delivers measurable benefits: reduced downtime due to reliable fault interruption, simplified integration with existing ABB control systems, and long-term durability in harsh operating environments. The selectable trip function enhances operational flexibility, enabling single-phase or three-phase tripping based on system needs. This interrupter is a direct replacement for aging vacuum interrupters in legacy switchgear, ensuring compatibility with ABB’s ecosystem while providing modern protection capabilities.
