Siemens 5 GMI 250 58 2000A

The Siemens 5 GMI 250 58 2000A is a medium-voltage vacuum circuit breaker engineered for reliable protection and control of electrical power distribution systems operating in demanding industrial and utility environments. Part of the proven GMI series, this breaker is designed for use in GM switchgear assemblies and provides dependable interruption of fault currents while maintaining system stability and equipment safety.

With a rated voltage up to approximately 4.76–5 kV and a continuous current rating of 2000A, the breaker is capable of handling high load requirements in substations, manufacturing plants, commercial facilities, and critical infrastructure installations. The vacuum interrupter technology ensures efficient arc extinction, minimal maintenance requirements, and long mechanical and electrical life compared to traditional air or oil breakers.

The draw-out construction allows easy installation, inspection, and servicing without disturbing connected bus systems, reducing downtime during maintenance. Electrically operated mechanisms with DC control voltage provide precise remote operation and integration into automated protection schemes. High interrupting capacity and fast operating times enhance protection against short circuits and overload conditions.

Built to meet recognized industry standards, the Siemens 5 GMI breaker is widely used in retrofit projects, replacement programs, and modernization of legacy switchgear systems where reliability and safety are essential.
