Square D | FI36020CBA | Circuit Breaker | 20A | 3-Pole | 600V

Meet the Square D FI36020CBA Circuit Breaker—a 20 A, 3‑pole protective device designed for robust 3‑phase circuits up to 600 V. Built for reliability in maintenance, retrofit, and replacement projects, this breaker ensures precise protection where it matters most in commercial and industrial panels.

• Amperage: 20 A
• Poles: 3‑Pole (protects all three phases)
• Voltage rating: up to 600 V
• Best use: maintenance, retrofit, and replacement to meet exact specifications

Why this matters in real-world setups: a 3‑pole design guarantees simultaneous fault interruption across all phases, reducing the risk of motor damage, electrical imbalance, and downstream equipment failures in 3‑phase systems. The 20 A rating provides appropriate protection for typical motor feeders, compressors, and other heavy loads without unnecessary trips.

Compatibility and fit guidelines: Notes: Confirm fit and ratings before ordering. The part number FI36020CBA is the best reference for compatibility with your Square D panels and associated bus configurations. Use this exact part when matching to existing breakers to maintain electrical safety and compliance.

• Ideal for: replacing a failed 3‑pole breaker in 3‑phase panels, upgrading protection on motor-driven equipment, or retrofitting older systems to current standards
• Common scenarios: manufacturing lines, HVAC control circuits, and commercial electrical rooms with 3‑phase loads
• Benefits over generic solutions: precise FIT with Square D enclosures, consistent trip characteristics, and reliable performance in demanding environments

Practical tips for installation and use: verify that your enclosure is designed for 3‑pole, 600 V devices and that conductor sizes align with local codes. Keep documentation handy—tracking the FI36020CBA part number helps ensure ongoing compatibility during future upgrades or panel refurbishments.
