3P15H | Circuit Breaker | 3-Pole | 240V

The 3P15H circuit breaker is your reliable safeguard for three‑phase 240‑volt systems, purpose‑built for industrial panels where precise compatibility matters. Designed for maintenance, retrofit, and replacement projects, this 3‑pole device delivers consistent overcurrent protection and fast isolation to keep your equipment running safely.

Key specifications

• Poles: 3‑Pole
• Voltage: 240V
• Part number: 3P15H
• Reference note: Confirm fit and ratings before ordering—the part number is the best reference for compatibility.

Why this model stands out

Unlike generic substitutes, the 3P15H is tailored for three‑phase industrial applications. Its 3‑pole configuration aligns with typical 3‑phase panel layouts, ensuring balanced protection across all phases. With a 240V rating, it’s suited for common industrial feeders and equipment circuits, helping you maintain stable, safe operation even under surge conditions. The clear emphasis on compatibility makes it a dependable choice for legacy panels or systems that require exact device lineage.

Ideal use cases

• Maintenance: Replace worn or aged breakers to restore reliable protection without changing your panel topology.
• Retrofit: Upgrade older systems to current protection standards while preserving existing wiring and bus configurations.
• Replacement: Swap in the 3P15H to maintain consistent specs in fleets of equipment sharing the same part reference.

How it solves real problems

Three‑phase electrical systems demand synchronized protection across all live conductors. The 3P15H delivers cohesive disconnection across all three poles, reducing the risk of undetected faults in one phase that could compromise equipment and safety. With the correct 240V, three‑pole configuration, you gain predictable trip behavior, easier troubleshooting, and faster recovery after faults.

Installation and care tips

• Before ordering, verify panel compatibility by matching the part number (3P15H) to your enclosure’s lineup and documented ratings.
• During installation, ensure power is fully de‑energized and all wiring conforms to applicable electrical codes and manufacturer instructions.
• Store and handle breakers in a clean, dry environment to prevent corrosion and maintain reliable performance over time.

What makes it the right choice

For engineers and technicians responsible for maintaining or upgrading three‑phase networks, the 3P15H offers a precise, traceable reference point for compatibility. Its 3‑pole, 240V specification aligns with common industrial panel architectures, making it a practical, drop‑in option when the goal is dependable protection without altering your system design.
