ge SKM3T400 400A 3-Pole Circuit Breaker

GE SKM3T400 is a robust 400A, 3-pole circuit breaker designed for demanding commercial and industrial electrical systems. With the part number SKM3T400, this unit delivers reliable overcurrent protection for three-phase networks, consolidating protection and control in a single, compact package.

What makes it stand out

• Three-pole configuration protects all three phases simultaneously, ensuring balanced protection for three-phase equipment and motors.
• 400 amp current rating provides strong, scalable protection for high-load feeders and main service disconnects in GE-compatible panels.
• Designed for GE SKM panels and distribution gear, enabling straightforward installation and seamless integration into existing GE-based electrical infrastructure.
• Part reliability and traceability—clear part number SKM3T400 simplifies stocking, ordering, and future replacements.

Ideal use cases

• Main disconnects and feeders in large commercial spaces, factories, and data centers that run three-phase equipment.
• Protection for high-power motors, pumps, fans, and other heavy-duty machinery that operate on a three-phase supply.
• Upgrade or replacement in GE-type panelboards where a 3-pole, 400A protection device is required.

Why this GE breaker benefits your system

• Targeted protection for three-phase systems minimizes the risk of unbalanced loads and arc faults across all phases.
• High-capacity protection supports sizable electrical draws, reducing nuisance trips for legitimate, peak-demand scenarios.
• Operational simplicity—a single device handles protection across all three lines, simplifying maintenance and diagnostics.
• Clear interchangeability within GE SKM offerings—facilitates smoother replacements and compatibility checks during panel servicing.

Installation and compatibility

Designed for use with GE SKM-series panels and distribution equipment, the SKM3T400 should be installed by a licensed electrician. Always verify that the panel labeling supports the SKM3T400’s frame and trip characteristics, and confirm that the surrounding wiring and terminations meet local electrical codes and manufacturer recommendations.

Practical tips for optimal performance

• Before installation, inspect the breaker for any shipping damage and confirm the SKM3T400 part number matches your order to avoid compatibility issues.
• Ensure all conductors are appropriately sized and torqued to the panel’s specifications to maintain reliable protection and minimize connection resistance.
• If upgrading from a lower amperage or a single-pole device, plan the replacement path to maintain balanced loading across the three phases.

For applications requiring robust three-phase protection, the GE SKM3T400 400A 3-Pole Circuit Breaker offers dependable, scalable performance with straightforward integration into GE-based electrical systems. Part number SKM3T400 makes ordering precise, so you can keep maintenance on track and minimize downtime in demanding environments.
