Siemens | NEB2B100B | Circuit Breaker | 100A | 2-Pole | 600V | 35kA | Bolt-On

Introducing the Siemens NEB2B100B circuit breaker — a robust, bolt-on protection device engineered for reliability in demanding electrical environments. This 2-pole unit delivers 100 A of protection at 600 V, with a 35 kA interrupting capacity, making it well-suited for maintenance, retrofit, and replacement projects where exact specifications matter.

Key specifications

• Amperage: 100 A
• Poles: 2-Pole
• Voltage: 600 V
• Interrupting capacity: 35 kA
• Mounting type: Bolt-On

Why these specs matter: a 100 A rating handles common commercial and industrial loads, while 35 kA of interrupting capacity provides a comfortable safety margin during fault events. The bolt-on design supports straightforward replacement or retrofit in compatible panels, reducing downtime and simplifying service interventions.

What problems does it solve?

Whether you’re upgrading an aging panel, replacing a failed breaker, or retrofitting to meet new protection standards, the NEB2B100B ensures consistent, reliable overcurrent protection that aligns with your existing Siemens installation. This part is a natural fit for projects where the original equipment specification is preserved and continuity of protection is essential.

Compatibility and installation notes

Important: confirm fit and ratings before ordering. The part number NEB2B100B is the best reference for compatibility. This breaker is designed for Siemens NEB2B-style bolt-on installations and 600 V electrical systems; verify that your panel accepts this mounting style and that the system’s protection requirements align with the 35 kA interrupting rating.

Who is this ideal for?

• Maintenance teams performing routine replacements in panels that accept NEB2B bolt-on breakers.
• Retrofit projects needing a precise 100 A, 2-pole, 600 V protection device.
• Facility managers seeking durable, Siemens-compatible protection to maintain equipment uptime and safety.
