FHL36045 - 45 Amp Circuit Breaker

FHL36045 - 45 Amp Circuit Breaker

The FHL36045 - 45 Amp Circuit Breaker by Schneider Electric provides efficient and dependable protection for commercial and industrial electrical systems. With a line‑rated current of 45 Amps and support for up to 600 V applications, it’s built to keep circuits secure and operational. The thermal‑magnetic trip unit safeguards against overloads and short‑circuits, giving you peace of mind that critical systems are protected. Whether you’re powering complex control panels, distribution boards, or heavy‑duty HVAC equipment, this breaker handles the workload with confidence while meeting demanding safety standards.

Key Features and Benefits

• Thermal‑Magnetic Trip Unit: Offers both long‑time and instantaneous protection so overloads and faults are addressed quickly and accurately.
• High Interrupting Capacity: Rated up to 65 kA at 240 V AC, 25 kA at 480 V AC and 18 kA at 600 V AC — able to handle high fault currents and reduce potential downtime.
• User‑Friendly Connectivity: Line and load lugs simplify installation and provide secure, reliable connections for copper and aluminum conductors.
• Three‑Pole Coordination: Ensures balanced protection across three phases (ABC) for stable performance in multi‑phase systems.
• HACR Rated & Versatile: Suitable for heating, air‑conditioning, and refrigeration equipment, expanding its suitability across various application types.
