Industrial HLCGA3400F 400A 3-Pole 600 V Circuit Breaker

Industrial HLCGA3400F 400A 3-Pole 600 V Circuit Breaker is a rugged, three-phase protection device designed for demanding industrial power systems. With a 400 A current rating, 3 poles for three-phase distribution, and a 600 V voltage rating, this unit delivers reliable protection for heavy feeders and critical equipment in industrial environments.

• Current rating: 400 A
• Poles: 3 (three-phase)
• Voltage rating: 600 V
• Part number: HLCGA3400F

Why choose this model matters in real-world setups. In industrial electrical rooms and production floors, a 3-pole breaker like the HLCGA3400F provides coordinated protection across all three phases, helping prevent damage from overloads and short circuits in three-phase feeders. Its 600 V rating aligns with common industrial power distribution standards, making it a practical choice for systems requiring robust, reliable trip protection.

Who this is ideal for

• Facilities with three‑phase power distribution that run heavy machinery, conveyors, or large motors
• Industrial panels where a main or feeder protection device needs to handle up to 400 A
• Electrical teams seeking traceable part numbers for maintenance, stocking, and replacements

Use cases and practical benefits

• Protect three-phase feeders and connected equipment from overloads, reducing the risk of wiring damage and unplanned downtime
• Serve as a reliable main breaker or branch protection in industrial distribution panels that operate at or below 600 V
• Facilitate safer electrical operation in manufacturing lines, processing plants, and heavy-duty industrial environments

Designed for dependable performance in real-world conditions, the HLCGA3400F supports maintenance practices and system resilience. Its clear part-number traceability simplifies sourcing, replacement, and compatibility checks during upgrades or panel refurbishments. When integrated into a compliant 3-phase distribution setup, this breaker helps maintain electrical stability and protects both wiring infrastructure and critical equipment from fault conditions.

Installation and maintenance considerations

• Install in compatible industrial panels that support three-phase protection at 600 V
• Pair with properly sized conductors and ensure secure, compliant mounting and electrical connections
• Schedule regular inspections to verify mechanical integrity and check for signs of wear or overheating in service environments
• Keep a stock of the exact part number (HLCGA3400F) for rapid replacements and consistent protection across the facility

If you’re upgrading an existing installation or specifying protection for a new three-phase system, the Industrial HLCGA3400F 400A 3-Pole 600 V Circuit Breaker combines clear 3‑phase protection with a straightforward 400 A capability. It’s a purposeful choice for engineers and technicians who need dependable, traceable, and standards-aligned circuit protection that keeps industrial operations running smoothly.
