Key specifications at a glance

• Amperage: 1000A
• Poles: 3-Pole
• Voltage rating: 600V
• Interrupting capacity: 30kA
• Configuration: Feed-Through
• Part reference: TKMA3Y1000

What makes this breaker stand out

The TKMA3Y1000 isn’t just about raw current capability. It’s built for integration into complex, three-phase power systems where a reliable fault interruption is critical. With a 30kA interrupting rating, it’s equipped to safely interrupt major fault currents, helping protect equipment and maintain system stability. The feed-through configuration simplifies wiring paths and downstream protection, streamlining installation in panels and switchgear that require power to pass through and continue to other circuit protection stages.

Ideal use cases

• Retrofits and replacements in aging or upgraded switchgear where the 3-pole, 600V, 1000A specification matches the existing setup
• Maintenance scenarios where a like-for-like part ensures compatibility and minimal downtime
• Industrial facilities, manufacturing lines, and large commercial panels needing strong, reliable three-phase protection
• New or upgraded electrical infrastructures that require feed-through capability for streamlined downstream distribution

Why choose the TKMA3Y1000 for your project

Compatibility is key in mission-critical electrical systems. The TKMA3Y1000 is crafted to align with exact GE standards for three-phase protection with feed-through design, reducing guesswork during replacement. When you reference the part number TKMA3Y1000, you’re aligning with GE’s documented specifications and recommended usage, delivering confidence that the breaker will fit both form and function in qualified installations.

Installation and compatibility notes

Always confirm fit and ratings before ordering. The best reference for compatibility is the TKMA3Y1000 part number itself, ensuring you match the exact trip characteristics and physical form required by your panel or switchgear. Before installation, verify that the panel’s bus rating, downstream wiring, and enclosure clearances accommodate a 3-pole, 600V, 1000A, feed-through breaker to avoid fit issues and ensure safe operation.

Practical tips for optimal performance

• Use in systems explicitly specified for 600V and 1000A service to prevent under- or over-rating components
• Leverage the feed-through configuration to simplify downstream protection wiring and reduce assembly complexity
• Maintain documentation tying this exact part number to your service records for future maintenance or replacements

With the General Electric TKMA3Y1000, you’re choosing a purpose-built, high-current, three-phase circuit breaker designed to deliver dependable protection in demanding industrial environments. Its precise specifications—1000A, 3-pole, 600V, 30kA, feed-through—ensure it fits targeted retrofit, maintenance, and replacement needs with clarity and confidence.
