Product description
Shipping
The HMC3400 is a rugged industrial circuit breaker engineered to protect 3‑phase 600V electrical systems with a robust 400A rating. Built for reliability in maintenance, retrofit, and replacement scenarios, this 3‑pole device keeps critical equipment safeguarded while simplifying compatibility decisions when updating aging panels or switchgear.
Designed for real‑world industrial use, the HMC3400 delivers immediate overcurrent protection for high‑demand circuits. Its 3‑pole configuration ensures synchronized protection across all phases, helping prevent unbalanced loads and reducing the risk of equipment damage during faults. This makes it a practical choice for service upgrades, panel revamps, or new installations that operate at 600V with a 400A service level.
Key specifications
- Amperage: 400 A
- Poles: 3‑Pole
- Voltage rating: 600 V
Note: Confirm fit and ratings before ordering. The part number HMC3400 is the best reference for compatibility with your equipment, enclosure, or panel. This ensures you’ll achieve seamless replacement without rewiring or modification.
Why choose the HMC3400
What sets the HMC3400 apart is its precise alignment with 3‑phase, 600V systems and its suitability for retrofit and replacement projects where exact specifications matter. Instead of guessing compatibility, you can rely on the dedicated part number to match your existing gear, minimizing downtime and unnecessary edits to wiring or mounting. It’s a practical, no‑nonsense solution for keeping industrial operations running smoothly.
Ideal use cases
- Maintenance swaps in service panels and distribution gear that operate at 600V
- Retrofits to upgrade older equipment to current 3‑phase protection standards
- Replacement in existing equipment that requires a 400A, 3‑pole, 600V circuit breaker
Practical tips for a smooth installation
- Verify that your panel or enclosure is designed for a 3‑pole 600V circuit breaker and that the mounting footprint matches the HMC3400
- Cross‑check the exact part number as the primary compatibility reference to avoid mismatches
- Prepare for a straightforward swap by having the same terminal configuration and wiring layout as your existing breaker
