Siemens NGG2B080 - 80 A, 600 V, 2-Pole Circuit Breaker | AmpState

Meet the Siemens NGG2B080—an 80A, 600V, 2-pole molded case circuit breaker designed to safeguard your branch circuits with precision in panelboards and load centers. Built for dependable overcurrent protection and fast short-circuit response, this device blends compact size with robust protection, making it ideal for a range of installations from homes to light industrial sites.

• Compact molded case design maximizes panel space, helping you fit more protection without crowding the enclosure.
• Thermal-magnetic trip unit delivers stable, repeatable protection across varying temperatures and fault conditions, reducing nuisance trips and ensuring reliable cutoff when it’s truly needed.
• 2-pole with common trip protects two conductors simultaneously and provides coordinated shutdown for 240V circuits where both legs must be interrupted together.
• 80A, 600V rating suitable for branch circuits in residential, commercial, and light industrial environments, offering strong protection for higher-load feeders and equipment.
• OEM-compatible design engineered to pair with matching Siemens OEM load centers and panelboards, ensuring proper fit, labeling, and predictable performance.
• Versatile application designed specifically for branch circuit overcurrent and short-circuit protection, helping maintain system integrity in panelboards and load centers.

The NGG2B080 stands out by delivering a precise protection profile in a compact form, so you can protect critical circuits without sacrificing panel layout. Its thermal-magnetic mechanism means the breaker responds appropriately to both sustained overloads and sudden faults, keeping wiring temperatures within safe limits and minimizing unintended interruptions.

Ideal use cases

• Residential service panels requiring reliable protection for large or high-demand circuits
• Commercial electrical rooms with mid-range feeder circuits and mixed-load panels
• Light industrial panels where space efficiency and robust short-circuit protection matter

Why choose this Siemens breaker—and why it belongs in AmpState’s lineup—boils down to fit, performance, and predictable protection you can trust. With OEM compatibility, you avoid panel mismatches and messy rework, while the 2-pole design ensures safe, simultaneous disconnect of multi-wire circuits. If you’re upgrading or stocking replacement parts for Siemens panelboards or load centers, the NGG2B080 provides a straightforward, reliable path to maintain code compliance and electrical safety.

In practice, this breaker helps electricians and facilities managers keep critical circuits safeguarded without sacrificing panel real estate or workflow efficiency. Whether you’re wiring a new installation or replacing an aging breaker in a Siemens panel, the NGG2B080 offers a concrete, long-lasting protection solution for your 80-amp, 600-volt needs.
