3CU5L | Circuit Breaker | 5A | 3-Pole | 480V

Designed for demanding industrial environments, the 3CU5L circuit breaker delivers precise, reliable protection for three-phase 480V systems. With a compact 3‑pole form and a 5A rating, it ensures safe interruption when faults occur, safeguarding motors, drives, and control circuits in retrofit, maintenance, and replacement scenarios.

• Amperage: 5A
• Poles: 3-Pole
• Voltage: 480V
• Reference: Part number 3CU5L (best compatibility reference)
• Application: Maintenance, retrofit, and replacement where matching specs are required

Why this 3CU5L matters for your system

When your panel or switchgear requires a precise 3‑pole, 480V protection device with a 5A interrupt rating, the 3CU5L provides a dependable fit. Its three‑phase design ensures simultaneous disconnection of all conductors, reducing the risk of phase imbalances and equipment damage during fault events. This makes it an ideal part for aging systems undergoing retrofit or for ongoing maintenance programs that rely on established part numbers for compatibility.

Ideal use cases

• Replacing a failed or obsolete 3‑pole breaker in 480V control cabinets and motor control centers
• Retrofit projects where existing equipment specifies 3CU5L or equivalent 3‑pole, 480V protection
• Maintenance inventories for facilities with 480V distribution networks and three‑phase equipment

Key benefits in practical terms

• Clear compatibility reference: using the 3CU5L part number minimizes guesswork during procurement
• Consistent protection for 480V three‑phase circuits, helping prevent motor and drive damage during faults
• Streamlined maintenance planning with a well-defined replacement component

Installation and compatibility tips

• Always verify fit and ratings against your panel label and the equipment’s documentation before ordering
• Use the 3CU5L as the primary compatibility reference when sourcing parts for 3‑pole, 480V systems
• Have a qualified electrician perform installation and follow local electrical codes and safety practices

For facilities relying on robust, standardized protection across 3‑phase 480V networks, the 3CU5L circuit breaker offers a precise, dependable solution tailored to maintenance, retrofit, and replacement needs.
