LB2100S | Circuit Breaker | 100A | 2-Pole | 600V

The LB2100S is a purpose-built industrial circuit breaker designed for reliability in maintenance, retrofit, and replacement projects where exact specifications matter. With a sturdy 2-pole construction and a 100A rating, this breaker delivers dependable overcurrent protection for demanding electrical environments at up to 600V. When a system needs a precise, drop-in solution that matches existing panels, the LB2100S stands out as the clear reference point.

Why the LB2100S stands apart

• Two-pole design for synchronized protection: Disrupts both conductors simultaneously to minimize arc risk and provide safe, clean disconnect in commercial and industrial circuits.
• 100A current rating: Suitable for sizeable loads and branch circuits common in industrial settings, while keeping protection aligned with standard panel specifications.
• 600V maximum voltage: Built to handle the higher voltages typical in industrial distribution, control panels, and machinery feeds.
• Retrofit-ready and replacement-focused: Engineered for maintenance and upgrade projects where matching specs simplifies installation and reduces downtime.
• Part-number accuracy matters: The LB2100S is the best reference for compatibility, helping installers confirm fit before ordering in complex panel systems.

Ideal use cases

• Maintenance tasks in aging or retrofit-ready electrical panels that require a like-for-like LB2100S replacement.
• Panel upgrades in manufacturing lines where a robust, 2-pole breaker is needed to protect large single-phase or multi-terminal circuits.
• New installations that must align with existing LB2100S specifications to ensure consistent protection across the system.
• Projects where minimizing downtime is critical, thanks to a straightforward part-number reference and compatibility with standard industrial panels.
