FPE LB-123 - 90A, 3-Pole, Circuit Breaker

The FPE LB-123 90A, 3-Pole Circuit Breaker is engineered for dependable three-phase protection in demanding electrical environments. With a 90-amp rating and a robust 3-pole configuration, this breaker is a versatile backbone for distributing power in panelboards, switchboards, and control panels. If your goal is safer operation and clearer protection across all phases, the LB-123 delivers.

• Current rating: 90A
• Poles: 3-Pole
• Breaker type: Circuit Breaker
• Supported configurations: Panelboards, switchboards, and control panels
• Ideal for: Industrial, commercial, and OEM applications requiring reliable overcurrent protection

Why choose the FPE LB-123 in your distribution setup? Its three-pole design provides coordinated protection for three-phase systems, ensuring all phases trip together when an overcurrent or fault is detected. This synchronization minimizes the risk of phase-to-phase faults that can damage motors, wiring, and downstream equipment, helping you reduce downtime and maintenance costs in mission-critical spaces like motor control centers (MCCs) and multi-panel installations.

Key use cases

• Feeding three-phase loads in distribution panels and MCCs where reliable, labeled overcurrent protection is essential
• Backup protection for commercial electrical rooms that house multiple motor-driven systems
• OEM cabinet designs requiring a compact, proven 3-pole circuit breaker with straightforward installation

The LB-123 stands out by combining a straightforward, durable design with practical three-phase protection for real-world applications. It’s suited for environments where continuous operation and clear, unambiguous protection signaling matter most. Whether you’re upgrading aging distribution gear or installing a new panel layout, this breaker helps you meet safety standards and keep electrical systems running smoothly.

Practical tips for deployment: verify compatibility with your panelboard or MCC bus arrangement, coordinate with upstream protective devices for proper selectivity, and document the 90A, 3-Pole configuration in your electrical drawings for clean maintenance records. With the FPE LB-123, you gain a trusted, three-phase safeguard that aligns with industrial, commercial, and OEM needs.
