General Electric’s TK4V4604GR is a purpose-built circuit breaker designed to deliver dependable overcurrent protection in demanding electrical installations. With a 400-amp rating, a three-pole configuration, and a 600-volt maximum, this unit is built to handle heavy loads while keeping your system safe and in proper working order.

Overview

The TK4V4604GR is the exact part you’ll want for maintenance, retrofit, or replacement projects where this model is specified. It’s a genuine GE component chosen for reliability and compatibility in mature or expanding electrical environments that rely on robust three-phase protection. Use it in scenarios where a hard current limit and secure trip performance are essential for equipment protection and uptime.

Key specifications

• Amperage: 400A
• Poles: 3-Pole
• Voltage rating: 600V
• Part number: TK4V4604GR

Why this model stands out

• Exact reference for compatibility: TK4V4604GR is the best reference when matching GE panels, switchgear, or assemblies that call for this specific model.
• Three-pole protection for 3-phase systems: Ideal for larger feeder circuits and commercial/industrial panelboards that rely on balanced protection across phases.
• High-current capability: 400A rating supports substantial main feeders or large branch circuits without compromising safety margins.
• Genuine GE part: Designed to work with GE labeling, documentation, and system design expectations, reducing installation surprises and compatibility issues.

Ideal use cases

• Maintenance and service work on GE equipment where a 3-pole, 400A, 600V breaker is specified.
• Retrofit projects updating older gear to current-rated protection without changing the surrounding switchgear.
• Replacement of a failed or worn breaker in commercial or light industrial environments that use GE panels.
• New installations where the system is designed around a 3-phase 400A main feeder or large distribution feeder.

Fit, compatibility, and installation tips

• Verify fit before ordering: Confirm that your equipment or panel requires TK4V4604GR by cross-referencing the panel labeling and catalog numbers. The part number is the most reliable reference for compatibility.
• Check ratings match: Ensure the system’s voltage and current levels align with 600V and 400A to avoid improper operation or nuisance tripping.
• Plan for proper installation: Install in a clean, vertical or horizontal orientation as specified by GE’s guidelines for this model, and follow standard electrical safety practices.
• Maintenance mindset: Keep a spare TK4V4604GR on hand for critical feeders in high-demand environments to minimize downtime during replacements.

Designed for reliability and ease of integration, the TK4V4604GR helps you protect valuable equipment, maintain continuity of service, and simplify your upgrade or replacement projects. If your panel or documentation calls for this exact model, you’re choosing a solution that aligns with GE engineering intent and your system’s protection strategy.
