Square D | KA36100MT | Circuit Breaker | 100A | 3-Pole | 600V

Square D KA36100MT circuit breaker, a robust 100A, 3-Pole, 600V solution designed for maintenance, retrofit, and replacement projects where exact specs matter. Built to deliver reliable overcurrent protection in demanding electrical environments, this unit helps keep equipment safe and operations steady.

Key features that set it apart:

• 100A current rating provides strong protection for heavy loads such as three-phase motors, pumps, and compressors.
• 3-Pole design with common trip ensures all three conductors disconnect together, reducing the risk of unbalanced or unsafe conditions in 3‑phase systems.
• 600V maximum voltage capacity makes it suitable for industrial distribution and commercial power panels requiring high-voltage protection.
• Authentic Square D part—reliable performance and compatibility you can trust for panel upgrades and service replacements.
• Compatibility-driven choice — the KA36100MT part number is the best reference for matching this breaker to your panel or retrofit kit.

Compatibility and installation notes

• Before you order, confirm fit and ratings for your specific panel or enclosure. The KA36100MT designation is the most reliable reference to ensure correct electrical characteristics and physical fit.
• Ideal for replacing a failed or aging breaker in three‑phase systems where a precise 100A, 3‑pole, 600V device is required.
• Common-use scenarios include service upgrades, panel retrofits, and ongoing maintenance in manufacturing facilities, data centers, and HVAC/control installations.

Why choose this KA36100MT breaker over generic replacements? It’s engineered to align with Square D specifications, ensuring consistent tripping behavior, electrical clearance, and mounting compatibility with compatible Square D panels. By sticking to the exact part number, you minimize compatibility risks and downtime, so maintenance crews can complete replacements quickly and confidently.

Ideal for electricians, facility managers, and panel technicians seeking a dependable, high‑value replacement that maintains system safety and performance in 3‑phase environments.
