Ls 52FB - 20A, 2-Pole, Circuit Breaker

Engineered for demanding distribution environments, the LS 52FB 20A, 2-Pole Circuit Breaker delivers precise, fast-acting overcurrent protection where reliability is non-negotiable. Its 2-pole design guarantees that both conductors trip together, providing a safe, synchronized shutdown that minimizes the risk of dangerous fault conditions and arc events in your panelboards, switchboards, and control panels.

Key specifications

• Current rating: 20A
• Poles: 2-Pole
• Breaker type: Circuit Breaker

Why the LS 52FB stands out

• Coordinated protection: The dual-pole design ensures both hot lines disconnect together, maintaining balance and reducing the potential for neutral or grounding issues during a fault.
• Rugged, industrial-grade construction: Built for continuous use in panelboards, switchboards, and motor control centers, this breaker resists wear and provides dependable protection in harsh environments.
• Versatile deployment: Ideal for industrial, commercial, and OEM applications where dependable overcurrent protection and safe operation are critical for distribution panels and control systems.
• Simple integration: Designed to fit standard panel configurations, making replacement or expansion straightforward in existing installations.

Ideal applications

• Distribution panels in manufacturing facilities and processing plants
• Motor control centers and equipment racks in industrial settings
• Commercial electrical enclosures requiring reliable 20A protection
• OEM equipment assemblies where compact, dual-pole protection is needed

Practical guidance for installation and use

• Choose the LS 52FB when your circuit load matches a 20A rating and you need simultaneous protection on two conductors.
• Verify compatibility with your panelboard or switchboard’s bus configuration and mounting footprint to ensure a smooth replacement or upgrade.
• During installation, ensure clean terminals and secure connections to maintain reliable trip performance and reduce contact resistance.
• Use this breaker as part of a comprehensive protection strategy that includes proper wiring practices, enclosure protection, and routine preventative maintenance.

For engineers and technicians designing or upgrading distribution schemes, the LS 52FB delivers nothing less than consistent, predictable overcurrent protection with tangible safety and reliability benefits in both new equipment and retrofit projects.
