Siemens | NEB3B080B | Circuit Breaker | 80A | 3-Pole | 600V | 35kA

Meet the Siemens NEB3B080B: a rugged, reliable 3-pole circuit breaker engineered for demanding industrial and commercial panels. Built to protect circuits, equipment, and people, this unit delivers precision performance where it matters most.

Key to its performance is its 80A amperage across three poles, designed for 600V systems. With a 35kA interrupting rating, it can safely clear high fault currents, helping to minimize equipment damage and downtime during electrical faults.

Key specifications

• Amperage: 80A
• Poles: 3-Pole
• Voltage rating: 600V
• Interrupting rating: 35kA
• Best reference for compatibility: Part number NEB3B080B

Important compatibility note: Confirm fit and ratings before ordering. The part number NEB3B080B is the most reliable reference to ensure this breaker matches your panel, enclosure, or replacement requirement.

Why choose the Siemens NEB3B080B

• Three-phase protection: The 3-pole design ensures synchronized interruption across all phases, reducing the risk of unbalanced loads and accidental single-phase faults.
• Robust fault clearance: A 35kA interrupting rating provides confidence when facing high fault currents common in commercial and industrial facilities.
• Retrofit and replacement ready: A direct-fit option for Siemens panels and compatible switchgear, helping maintenance teams upgrade or replace components with minimal downtime.
• Clear compatibility anchor: Use NEB3B080B as the definitive reference across catalogs, spare parts inventories, and service manuals.

Use cases and who it’s for

• Facilities engineers performing panel upgrades or retrofits in commercial buildings, data centers, and light industrial spaces.
• Maintenance teams stocking reliable spares for essential distribution panels to minimize unplanned downtime.
• Electricians replacing aging breakers in 600V systems where a precise 80A, 3-pole solution is required.

Practical tips for best results

• Before purchasing, verify that your enclosure labeling and catalog references align with the NEB3B080B specifications to ensure seamless replacement.
• Keep a small inventory of compatible breakers to reduce service interruptions during upgrades and repairs.
• Store spare breakers in a clean, dry environment to maintain performance and longevity.
