BR355 | Circuit Breaker | 55A | 3-Pole | 240V

Overview

The BR355 is a rugged industrial circuit breaker designed for reliable protection in maintenance, retrofit, and replacement projects where exact compatibility matters. This 3-pole, 240V unit delivers a 55A rating, providing synchronized protection across a three-phase system and helping keep motors, controls, and distribution safely powered.

Key Specifications

• Amperage: 55A
• Poles: 3-Pole
• Voltage: 240V
• Part Number: BR355

Ideal Applications

Designed for industrial environments, the BR355 excels in:

• Maintenance and service tasks on legacy panels requiring a specific 3-pole, 240V protection profile
• Retrofits where upgrading to a compatible breaker maintains system protection without rewiring
• Replacement of worn or failed breakers in 3-phase power distribution and motor control centers

Why Choose BR355

• Direct compatibility reference: The BR355 is the best match for panels and assemblies that call for this exact part number. Using the BR355 helps preserve original protection schemes and trip characteristics.
• Three-phase protection in one device: A 3-Pole design ensures all phases trip together, reducing the risk of phase imbalance and equipment damage in 240V systems.
• Focused on industrial reliability: Built to withstand the demands of industrial environments, where consistent protection is essential for uptime.

Installation & Compatibility Notes

Before ordering, confirm fit and ratings against your equipment. The part number BR355 serves as the most reliable reference for compatibility with your panel or motor control setup. When installing, follow standard lockout/tagout procedures and panel manufacturer guidelines to ensure a safe, effective replacement or retrofit.

Use Case Scenarios

Imagine a mid-size manufacturing line powered by a 3-phase 240V distribution where a single device needs protection without altering the surrounding circuitry. The BR355 offers a precise, compatible solution for safeguarding line equipment, reducing nuisance trips, and simplifying future maintenance by keeping a consistent, readily identifiable breaker in service.

If you’re upgrading an aging panel or restoring service after a fault, the BR355 provides a clear path to restore reliable protection without extensive rewiring or custom adaptations—making it a practical choice for technicians and facilities teams aiming for dependable, long-term performance.
