ABB Vmax 12.06.32 M2

The Vmax 12.06.32 M2 is an indoor medium voltage vacuum circuit breaker from ABB Vmax series, rated at 12kV, 630A and 31.5kA short-circuit breaking capacity. This Vmax 12.06.32 M2 adopts integrated monobloc solid insulation structure with embedded vacuum interrupters, eliminating SF6 gas and delivering stable arc extinction performance for power distribution protection. The Vmax 12.06.32 M2 is equipped with spring energy-stored modular operating mechanism, supporting local manual operation and remote electrical closing and tripping for flexible control in switchgear cabinets.

This Vmax 12.06.32 M2 is designed for withdrawable truck mounting inside UniGear medium voltage switchgear. The Vmax 12.06.32 M2 features mechanical and electrical interlock functions to prevent unsafe racking operations when the breaker is closed, ensuring operator safety during inspection and maintenance. It can be matched with various protection relays to implement overload, short-circuit and earth fault protection for transformers, motors and feeder circuits. The Vmax 12.06.32 M2 complies with IEC 62271-100 standard and has a long mechanical service life with low routine maintenance requirements.

The Vmax 12.06.32 M2 is widely used in industrial substations, power plants, water treatment and mining power distribution systems. Standard accessories for the Vmax 12.06.32 M2 include auxiliary contacts, under-voltage releases, shunt trips and position signalling units. Many electrical maintenance teams stock the Vmax 12.06.32 M2 as spare breaker for switchgear overhaul and emergency fault replacement of existing UniGear installations.
