Eaton Cutler-Hammer SNT5LP03K 1200A 3P 600V Circuit Breaker, Shunt Trip | AmpState

The Eaton Cutler-Hammer SNT5LP03K is a high-capacity, three-pole circuit breaker purpose-built for demanding electrical environments. Rated at 1200 A and 600 V, this device delivers precise overcurrent protection for panelboards, load centers, and distribution circuits, helping keep critical systems up and running with confidence. Its integrated shunt trip capability provides immediate remote tripping, enabling fast, safe shutdowns from a control room or safety interface when every second counts.

Distinctive value in a single device

• Integrated shunt trip for remote operation: Instantly isolate circuits in emergencies or during automated safety sequences, reducing exposure to fault conditions and enabling coordinated safety protocols.
• 3-pole design for balanced protection: Ensures synchronized interruption across all phases in three-phase systems, safeguarding equipment and minimizing voltage imbalances.
• High-capacity performance: 1200 A rating makes it suitable for main feeders and heavy-duty distribution tasks in commercial, industrial, and data-center environments.
• retrofit-friendly, with consistent part numbers: Built for everyday electrical work and maintenance planning where keeping the same part number simplifies stocking and service intervals.
• Reliability from a trusted brand: Eaton Cutler-Hammer reliability supports long service life in harsh or variable environments, reducing nuisance trips and maintenance cycles.
• AmpState availability and support: Easy to source and verify compatibility through AmpState, with guidance to confirm fit for your panelboard or load center.

Practical applications and use cases

Ideal for facilities that require robust protection with the option for remote shutdowns, the SNT5LP03K shines in:

• Industrial plants and manufacturing lines where rapid isolation protects personnel and equipment during faults or process faults.
• Commercial buildings with centralized control systems that coordinate safety interlocks and emergency shutdowns.
• Data centers and critical infrastructure where dependable distribution protection and clear maintenance paths are essential.
• Retrofit projects where the part number must remain consistent to avoid documentation and wiring changes.
