Square D HJL36050CA Circuit Breaker, 50A, 3-Pole, 600V

Engineered for reliability in demanding industrial environments, the Square D HJL36050CA circuit breaker delivers precise overcurrent protection for three-phase electrical systems up to 600V. With a 50-amp rating and three poles, it intercepts overloads and short circuits quickly, safeguarding motors, drives, and feeders in manufacturing facilities, data centers, and large commercial spaces.

Key benefits

• Three-pole protection for balanced three-phase circuits, ensuring coordinated protection across all phases.
• 50 A rating matches common motor feeders and distribution branches, helping to optimize system performance and safety.
• 600V maximum system voltage suitable for industrial power distributions and high-demand environments.
• Part number accuracy with HJL36050CA to ensure precise compatibility within the Square D product family.
• Ideal for service, maintenance, and replacement projects where reliable, quick-fit protection is critical.

Why this breaker stands out

Unlike generic protectors, the HJL36050CA is designed to align with Square D panels and enclosures, providing predictable trip behavior, clear coordination with upstream protections, and a proven track record in industrial applications. Its three-pole configuration supports efficient, uniform protection across all phases, reducing the risk of unbalanced faults and equipment damage.

Ideal use cases

• Replacing aging breakers in industrial control panels and switchgear
• Providing robust protection for three-phase motors, conveyors, and drives
• Part of a proactive maintenance program to minimize unexpected downtime
• New installations requiring a 50 A, 3-pole, 600V circuit breaker's reliability

Compatibility and installation notes
