QRH22B250 - 250 Amp Circuit Breaker

QRH22B250 - 250 Amp Circuit Breaker

Bring reliable, high-capacity protection into your electrical system with the QRH22B250, a 2-pole molded-case breaker rated for 250 amps and 240 V operation. Designed to safeguard your circuits against overloads, short circuits, and high fault currents, this breaker is ideal for heavy loads like HVAC, industrial machinery, or demanding service panels. With a compact 7-inch height and about 3 lb weight, it’s engineered to fit cleanly into many standard panels while still delivering strong performance.

This unit integrates Siemens’ QRH2 frame and molded case materials that resist heat and wear, ensuring long service life and consistent protection. Its load-side lugs simplify wiring and installation, making your job faster and more reliable. The breaker also carries HACR certification, meaning it’s entirely suitable for equipment in heating, air conditioning, and refrigeration applications.
