FA36020 **Old Style** 20 Amp Circuit Breaker

FA36020 **Old Style** 20 Amp Circuit Breaker

The Schneider Electric FA36020 is a heavy‑duty, three‑pole, 600 V circuit breaker designed to protect industrial and commercial electrical systems from overloads and short circuits. Built with thermal‑magnetic trip unit technology, this breaker delivers dependable interruption of fault currents and consistent performance in demanding environments. Its I‑Line plug‑in mounting makes installation fast and easy, while the HACR‑rated design ensures compatibility with heating, air‑conditioning, and refrigeration loads. Whether you’re specifying equipment for a mechanical room, control panel, or production facility, the FA36020 offers high‑capacity protection that meets both safety and regulatory expectations.

Key Features and Benefits

• Accurate circuit protection: The thermal‑magnetic trip unit ensures dependable performance under both overload and short‑circuit conditions, guarding expensive assets and minimizing unplanned downtime.
• Plug‑in I‑Line installation: The I‑Line mounting offers a streamlined installation process with line‑side connection already optimized, reducing labor time and installation complexity.
• High short‑circuit interruption ratings: With a magnetic hold current of 275 A and magnetic tripping current of 600 A, the unit can safely handle severe fault conditions and keep system integrity intact.
• HACR‑rated versatility: Suitable for use in HVAC, refrigeration, and other mechanical systems, making it a flexible choice for MEP contractors and facility engineers.
• Compact yet powerful design: With dimensions of only 6.4 in (162.6 mm) height × 4.5 in (114.3 mm) width × 4.13 in (104.9 mm) depth, it fits panel‑board layouts where space is at a premium.
