Generator Mounted Breaker​

Trystar Custom Generator Mounted Circuit Breaker Switchboards (GMCB Series) are tailored circuit protection solutions, and help increase safety, reliability, and efficiency in power plants, industrial, and mission-critical environments. Generator-mounted circuit breakers are protective devices installed directly on a generator’s frame, helping protect the generator from damage caused by short circuits and overloads. Customize each Trystar unit to match its application needs, including the number of breakers, trip types, and the specific generator it mounts on. The cabinet paint will match the generator set and replace the factory-provided output breaker.

Features

  • Brand Specific Generator Mounted Enclosed Circuit Breaker – Custom-engineered to meet specific generator manufacturer mounting specifications and electrical requirements, ensuring direct compatibility with the specified generator set. 
  • Matched Paint to Manufacturers Gen Set – Factory-matched paint color creates a professional, unified look that blends with the generator manufacturer’s finish, maintaining a cohesive appearance important for visible installations in commercial buildings, hospitals, and data centers. 
  • Cabinet Mounted Directly to Generator – Direct mounting to the generator set eliminates separate enclosure foundations and conduit runs, reducing installation labor and materials while keeping breaker protection immediately adjacent to the power source for code compliance.
  • Custom Configured Units – Configure the exact number of breakers, trip settings, and protection types needed for each installation, which supports a wide variety of load requirements and protection systems without over-buying oversized packages or multiple separate enclosures. 
  • Replaces Factory-Provided Output Breaker – Upgrades or replaces original factory breakers with custom-built alternative with multiple circuits, different trip characteristics, or higher capacities for greater flexibility that meets exact application requirements. 
  • 100–5000 Amp Range – Offers a wide amperage selection, from small standby generators through large industrial gen sets, ensuring proper overcurrent protection is properly and safely sized. 
  • Up to 600 Volts Rating – Supports standard generator voltages, including 208V, 240V, 480V, and 600V systems for safe operation across commercial and industrial generator applications.
