HLCG3300 | Circuit Breaker | 300A | 3-Pole | 600V

The HLCG3300 is an industrial-grade circuit breaker designed to safeguard demanding 3-phase electrical systems. With a robust 300 A rating and a 3-pole configuration, this unit provides reliable protection for panels and equipment operating up to 600 V. Built for maintenance, retrofit, and replacement projects, it’s the precise component you need when uptime and safety matter most.

Key specifications

• Amperage: 300 A
• Poles: 3-Pole (three-phase)
• Voltage: 600 V
• Part number: HLCG3300

Why this matters for your panels

When upgrading or maintaining large electrical panels, a correct fit is essential. The HLCG3300 is purpose-built for industrial environments where three-phase protection at higher currents is required. Its 3-pole design helps coordinate protection across all three phases, simplifying wiring and improving reliability in motor drives, compressors, pumps, and other heavy loads common in manufacturing and infrastructure projects.

Ideal use cases

• Maintenance of existing service panels that use 600 V, 3-phase circuits
• Retrofit or replacement of aging breakers in industrial equipment
• New installations where a matching 300 A, 3-pole, 600 V specification is needed

How to ensure the right fit

Before ordering, verify compatibility by cross-referencing the panel’s catalog with the HLCG3300 part number. The part number is the most reliable reference for compatibility, helping you avoid mismatches that could affect protection or form factor. Always confirm both the amperage and voltage ratings align with your system requirements and that your enclosure supports a three-pole 600 V breaker.

Practical tips for best results

• Keep a spare HLCG3300 on hand for planned maintenance and unexpected field service.
• Store breakers in a clean, dry environment to prevent corrosion and ensure smooth operation during installation.
• Consult your panel’s documentation or a qualified electrician to confirm proper mounting, wiring, and trip characteristics for safe, compliant operation.

Designed to deliver dependable protection in industrial settings, the HLCG3300 is a thoughtful, exact-fit solution for panel upgrades, retrofits, and replacements that demand rigorous specifications and long-term reliability.
