Siemens | CE3B020 | Circuit Breaker | 20A | 3-Pole | 600V | Bolt-On

Meet the Siemens CE3B020 Circuit Breaker—a purpose-built, three-pole protection solution designed for reliable performance in demanding electrical environments. With a 20 A rating and a 600 V maximum, it delivers solid overcurrent protection for three-phase systems while fitting into bolt-on installations that prioritize secure, vibration-resistant connections.

• Three-pole design at 20 A provides synchronized protection across all phases in 3‑phase circuits, helping prevent unbalanced loads and equipment damage.
• Bolt-on mounting offers a robust mechanical connection and straightforward field replacement, reducing installation time and ensuring long-term contact integrity.
• 600 V operating voltage supports a wide range of commercial and industrial equipment, enabling safe protection for higher-voltage distributions.
• Siemens part CE3B020 as the definitive reference for compatibility, making it ideal for maintenance, retrofit, and replacement projects where exact specs matter.
• Maintenance-friendly and retrofit-ready designed to drop into panels that require bolt-on trip devices, streamlining upgrades and routine servicing.

Why this matters If you’re upgrading aging panels or performing routine maintenance in a facility with three-phase equipment, the CE3B020 delivers predictable, stable protection. Its bolt-on design minimizes installation complexity and gear loosening over time, a real advantage in environments with vibration, temperature swings, or frequent service cycles.

Typical use cases include replacing a failed breaker in Siemens bolt-on panels, retrofitting older electrical rooms to meet modern protection standards, or expanding capacity in commercial or light industrial installations where a 20 A, 3-pole, 600 V device is required.

Compatibility notes Always confirm fit and ratings before ordering. The most reliable reference is the part number CE3B020, which aligns with panels and bus configurations designed for bolt-on Siemens breakers. If your panel accepts 3-pole, bolt-on devices at a 600 V rating, this breaker is a precise match for your replacement or retrofit needs.
