HMCA2400 | Circuit Breaker | 400A | 2-Pole | 600V

The HMCA2400 is a robust industrial circuit breaker engineered for reliability in demanding power distribution environments. With a 400A rating and a 2-pole design, this unit provides strong protection for high-current feeders while ensuring safe, simultaneous disconnection of both conductors. Ideal for maintenance, retrofit, and replacement projects, it helps keep critical equipment and facilities running smoothly.

• Amperage: 400A, delivering strong protection for high-load circuits without compromising service continuity.
• Poles: 2-pole construction ensures both hot lines trip together for complete circuit isolation.
• Voltage rating: 600V, suitable for a wide range of industrial power distribution networks.
• Application focus: Designed for maintenance, retrofit, and replacement where matching specs are required to maintain system integrity.

Why this matters for your project

• The part number HMCA2400 is your best reference for matching panels, gear, and upstream protection schemes. Before ordering, confirm fit and ratings to avoid downtime or compatibility issues.
• When upgrading older installations or replacing a failed unit, this breaker aligns with high-current feeders and 600V networks, helping shorten installation timelines.
• By sticking to the exact 400A, 2-pole, 600V specification, you preserve electrical characteristics across the distribution system and minimize the need for cascading changes elsewhere in the panel.

Ideal for

• Industrial facilities with high-demand feeders needing reliable 400A protection
• Maintenance teams performing scheduled replacements in commercial or manufacturing environments
• Retrofit projects upgrading legacy panels to current protections without overhauling the entire distribution rig

Practical guidance for procurement and installation

• Keep the exact part number handy (HMCA2400) to verify compatibility with your panelboard or switchgear.
• Cross-check your system’s voltage (600V) and current requirements (400A) to ensure this breaker aligns with the broader protection scheme.
• Plan for a short downtime window during replacement tasks to minimize disruption to critical operations.
• Store spare units on-site in a labeled enclosure to support rapid replacements and reduce downtime when failures occur.
