HGA36045 - 45 Amp Circuit Breaker

HGA36045 - 45 Amp Circuit Breaker

If you’re looking for a heavy-duty, dependable circuit breaker to anchor your electrical distribution panel, the HGA36045 delivers just that — and more. This 3‑pole, 45-amp molded‑case breaker is built on the I‑Line “HGA” frame and offers reliable thermal-magnetic protection for industrial, commercial, or demanding residential applications. With a high interrupting capacity and plug-in design, it’s engineered to handle challenging conditions while keeping your system safe and efficient.

Key Features and Benefits

• High Interrupting Capacity (A.I.C.): Rated at 18 kA at 600 VAC, 35 kA at 480 VAC, and 65 kA at 240 VAC, this breaker gives you power-fault protection when it counts.
• 3-Pole Configuration: Perfect for three-phase circuits, providing balanced protection across all phases for motors, HVAC, or heavy loads.
• Plug-In I‑Line Frame: Easy installation and quick replacement with plug-in I-Line compatibility — a real time-saver during maintenance or upgrades.
• Thermal-Magnetic Trip Unit: Combines long-term overload protection with instantaneous short-circuit response, reducing risk of damage to wiring and equipment.
• Molded Case Housing: Compact yet durable — designed to endure everyday wear and tear inside electrical panels without compromising safety.
