Phoenix 83D - 04A, Circuit Breaker

Phoenix 83D - 04A Circuit Breaker delivers precise overcurrent protection for industrial and commercial electrical systems where reliability matters most. Designed to be installed in panelboards, switchboards, control panels, and OEM equipment, this 04A-rated breaker ensures safe operation and dependable protection across demanding environments.

The 04A current rating targets small to mid-size load circuits, making it an ideal choice for protecting compact motors, control circuits, and other equipment that draw modest continuous current but require fast fault clearing to prevent damage. This breaker helps keep distribution panels and motor control centers running smoothly by preventing overloads and short circuits from propagating through your system.

Key advantages

• Precisely rated at 04A to protect low-current circuits without nuisance trips, supporting coordinated protection across your panel.
• Versatile mounting and integration in panelboards, switchboards, control panels, and OEM equipment, reducing integration headaches in new builds or refurbishments.
• Reliable overcurrent protection for distribution panels and motor control centers, helping minimize downtime and equipment wear from electrical faults.
• Robust electrical protection for industrial environments—built to perform in the demanding conditions typical of commercial facilities and manufacturing settings.
• OEM-friendly applicability suitable for inclusion in custom equipment and assembled systems where you need proven protection without compromising space or workflow.
