General Electric | TK4V4604 | Circuit Breaker | 400A | 3-Pole | 600V | Bolt-On

Engineered by General Electric, the TK4V4604 circuit breaker delivers dependable overcurrent protection for 600V electrical systems. With a 400A rating and a three-pole configuration, this bolt-on unit is built for maintenance, retrofit, and replacement projects where exact specifications matter. Use the TK4V4604 when your panel or distribution system calls for a 3-pole, 600V, 400A bolt-on breaker, and rely on the part number as the most reliable compatibility reference.

Key specifications

• Amperage: 400A
• Poles: 3-Pole
• Voltage: 600V
• Mounting: Bolt-On
• Part number: TK4V4604

Who this is for

• Maintenance teams performing routine replacements in industrial panels and switchgear operating at 600V.
• Retrofit projects where existing gear requires a precise 3-pole, 400A bolt-on breaker to restore full protection and functionality.
• System upgrades that necessitate upgrading to a higher-current or more robust overcurrent protection strategy within compatible GE or GE-spec panels.

What makes this breaker unique

The TK4V4604 isn’t a generic substitute. It’s a genuine General Electric part designed to align with GE’s electrical architectures, ensuring secure mechanical mounting, reliable electrical contact, and predictable tripping behavior in demanding environments. The bolt-on design simplifies field installation by providing a solid, vibration-resistant connection to the panel bus, which translates to fewer loose connections and maintenance calls over time. This specificity—400A, 3-pole, 600V, bolt-on—helps prevent costly mismatches during critical replacements or retrofits.

Practical use cases and scenarios

• Replacing a failed 400A breaker in a 600V motor control center or distribution panel without reconfiguring the enclosure.
• Upgrading an older electrical setup to meet current protective-device requirements, while preserving the existing 3-pole, 600V system topology.
• Performing preventative maintenance where you keep a stock of compatible TK4V4604 units for rapid field swaps, minimizing downtime.

Why choose a bolt-on design

A bolt-on circuit breaker like the TK4V4604 provides a robust, clamped connection to the panel’s bus bars, reducing the risk of arcing and loosening under vibration. This design is particularly advantageous in industrial settings where panels endure mechanical stress. It also simplifies replacement workflows, as technicians can secure the unit with standard mounting hardware without needing specialized tools or adapters.

Installation & safety notes

• Only qualified personnel should install or replace breakers. Ensure all power is isolated and system voltage is confirmed safe before working.
• Verify exact fit and ratings against the panel manufacturer’s specifications. The TK4V4604 part number is the most reliable compatibility reference.
• Follow the enclosure’s torque requirements and GE’s installation guidelines to secure the bolt-on mounting properly.
• After installation, perform a functional test to confirm proper tripping behavior and alignment with upstream protection.

What you get

A genuine General Electric TK4V4604 circuit breaker designed for 3-pole, 400A protection in 600V systems, built for durable bolt-on mounting and dependable, field-proven performance in demanding industrial environments.

Compatibility and ordering tips

Before purchasing, cross-check that your panel or switchgear expects a 600V, 3-pole bolt-on breaker in the 400A range and confirm the exact GE part number TK4V4604 for compatibility. If your system requirements align with these specifications, this breaker offers a precise, reliable solution that supports your maintenance, retrofit, and replacement objectives.
