Siemens NGG2B015L - 15 A, 600 V, 2-Pole Circuit Breaker | AmpState

The Siemens NGG2B015L is a 2-pole molded-case circuit breaker rated for 15 amperes and 600 volts, purpose-built to deliver reliable branch circuit overcurrent and short‑circuit protection in panelboards and load centers. Its compact molded-case design helps you maximize panel space without sacrificing protection, making it a practical choice for modern electrical installations.

Why this breaker stands out:

• Space-efficient design: The compact molded-case format fits tighter panel layouts, freeing room for additional circuits while maintaining robust protection.
• Thermal-magnetic trip unit: Combines thermal overload sensing with magnetic short-circuit protection for fast, repeatable response across varying temperatures and fault conditions.
• Plug-and-play compatibility: Engineered to pair with matching OEM load centers and panelboards for a secure fit, predictable tripping behavior, and straightforward replacement.
• Versatility across settings: Suitable for residential, commercial, and light industrial applications, protecting lighting, receptacles, small motors, and control circuits.

Technical essentials:

• Manufacturer: Siemens
• Part number: NGG2B015L
• Type: Thermal-magnetic molded case circuit breaker
• Amperage rating: 15 A
• Voltage rating: 600 V
• Poles: 2
