Siemens | NGG3B080L | Circuit Breaker | 80A | 3-Pole | Bolt-On

Meet the Siemens NGG3B080L, a purpose-built circuit breaker engineered for reliable three‑phase protection in commercial and industrial electrical systems. With an 80A rating and a 3‑pole configuration, this bolt‑on unit is ideal for maintenance, retrofit, and replacement projects where exact specifications matter and compatibility is non‑negotiable.

Key specifications

• Amperage: 80 A
• Poles: 3‑Pole (three‑phase)
• Mounting: Bolt‑On
• Reference: Part number NGG3B080L

Why this breaker makes sense

• The NGG3B080L is the best reference for matching Siemens panels and configurations, ensuring a seamless drop‑in replacement when upgrading or renewing protection in existing systems.
• Bolt‑on mounting provides a robust, vibration‑resistant fit that stays put in demanding environments.
• Designed to protect three‑phase distribution circuits, motor feeds, and equipment in commercial spaces, data centers, and light industrial applications.
• A practical choice when upgrading legacy gear or expanding panel capacity without changing the overall electrical architecture.

Ideal use cases

• Retrofit projects in existing Siemens panels that require a direct NGG3B080L match
• Maintenance replacements to restore consistent 3‑phase protection
• New installations in three‑phase distribution systems where bolt‑on mounting is preferred

Best practices for ordering and installation

Before purchasing, confirm fit and ratings against your panel model and bus configuration. The part number NGG3B080L serves as the most reliable reference for compatibility, ensuring you get the correct trip characteristics and mounting method for your setup.
