NFS390 | Circuit Breaker | 90A | 3-Pole | 240V

Meet the NFS390, a purpose-built industrial circuit breaker engineered to protect and power demanding electrical systems. With a precise 90A rating, a robust 3-pole configuration, and a 240V operating envelope, this unit is ready to shield mediumpower panels, motor control centers, and distribution boards from overloads and short circuits.

Designed for real-world maintenance, retrofit, and replacement projects, the NFS390 stands out where matching specs matter most. When upgrading legacy gear or reconfiguring a panel for three‑phase operation, this breaker provides dependable protection without the guesswork.

• Amperage: 90A — strong enough for medium-load circuits while preserving trip sensitivity for equipment safety.
• Poles: 3-Pole — ideal for three-phase systems, ensuring balanced protection across all phases.
• Voltage: 240V — compatible with standard industrial distribution networks and equipment ratings.

Why choose the NFS390 for your project?

• Built to endure frequent operation cycles and the rigors of commercial or manufacturing settings.
• Clear compatibility reference: The part number is the best guide for ensuring a perfect fit in your panel or MCC/drive assemblies.
• Maintenance-ready: A straightforward replacement that minimizes downtime and keeps your systems online.
• Precision protection: Precise current ratings and three-pole configuration deliver consistent overload protection across all phases.

Practical usage scenarios

• Upgrading older control panels to meet current safety standards without a full panel redesign.
• Replacing a failed or worn-out breaker in a three-phase distribution network that operates at 240V.
• Incorporating into retrofit projects where a standard, widely supported 90A, 3-Pole, 240V protection device is required.

Important note: Before ordering, confirm fit and ratings for your exact application. Use the NFS390 part number as the primary reference to ensure compatibility with your enclosure, bus, and trip characteristics, and verify that 90A, 3-Pole, and 240V align with your system's safety and regulatory requirements.
