Meet the ABB SB340SGL4G circuit breaker—a robust, 3-pole protection device engineered for 600V systems and 400A circuits. Designed for maintenance, retrofit, and replacement projects, this unit ensures reliable overcurrent protection when it matters most in demanding industrial environments.

  • Amperage: 400A
  • Poles: 3-Pole
  • Voltage: 600V

Why this ABB breaker stands out: the 3-pole design provides synchronized disconnection across all three lines, which helps minimize arc risk and keeps panels and connected equipment safe during fault conditions. It’s built to deliver consistent performance in the kinds of heavy-use settings where downtime isn’t an option.

Key use cases and ideal applications:

  • Maintenance projects where existing equipment requires a precise spec match to avoid panel incompatibilities
  • Retrofits that upgrade protection without changing downstream wiring or drive systems
  • Replacement in industrial distribution boards that rely on ABB SB-series compatibility
  • Service center spares for manufacturing lines, warehouses, and facilities with 600V three-phase distribution

Compatibility and purchasing tips: use the part number SB340SGL4G as the primary reference to confirm fit with your existing panel or switchgear. Before ordering, verify that the amperage (400A) and voltage rating (600V) align with your system requirements and that the unit’s specifications match the panel labeling and catalog data for your equipment.

Practical notes for handling and installation: store and transport the breaker in its original packaging, handle with care to avoid mechanical damage, and ensure the installation is performed by qualified personnel following all safety procedures. This ABB circuit breaker is a precise, purpose-built component designed to deliver dependable protection when you need it most.

Ready to implement or stock for future needs? Add the ABB SB340SGL4G to your cart and ensure your 600V, 400A, 3-Pole protection is ready to perform when it’s needed most.
