Why the THJ4VF16 is a strong fit for your system

Designed for reliability in three-phase networks, the THJ4VF16 provides robust overcurrent protection essential for equipment like large motors, conveyors, and switchgear assemblies. Its 600V rating supports a wide range of industrial and commercial applications, helping to prevent electrical faults from cascading into downtime or equipment damage. This breaker is ideal for maintenance, retrofit, and replacement tasks where the exact GE-compatible specifications are required to maintain system integrity.

Key benefits that matter in the field

• Precise compatibility: Designed to match GE panels and GE-compatible gear, ensuring a seamless replacement experience when the part number THJ4VF16 is referenced.
• High-capacity protection: 400A protection level supports heavy feeders and main circuits without compromising safety or performance.
• Three-phase reliability: The 3-pole configuration is ideal for balanced three-phase systems common in manufacturing floors and data-center infrastructure.
• Versatile retrofit option: Useful for upgrading older installations or swapping out failed breakers while maintaining the exact electrical characteristics your system expects.

How to ensure a perfect fit

Before ordering, verify your panel’s requirements align with the THJ4VF16’s specifications. The part number is the best reference for compatibility, so cross-check it against your panel schedule or service manual. Although the THJ4VF16 is built to general GE standards, confirm the current rating, pole configuration, and voltage rating match your existing setup to avoid mismatches during installation.

Practical usage scenarios

Consider the THJ4VF16 for:

• Replacing a failed 3-pole, 400A breaker in a GE-controlled panel.
• Retrofits where a high-amperage, three-phase protection device is required for motors or large loads.
• Maintenance cycles in industrial facilities with consistent GE infrastructure and parts alignment.

Installation and safety note

To maintain electrical safety and performance, have a qualified electrician install the THJ4VF16 and verify all connections and ratings. Maintain proper documentation with the part number for future maintenance or replacement planning.
