QR22B200 - 200 Amp Circuit Breaker

QR22B200 - 200 Amp Circuit Breaker

Protect your electrical systems with confidence using the Siemens QR22B200 — a high-capacity, 2-pole molded case breaker built for demanding 240 VAC applications. With a 200 A continuous rating and a 10 kA interrupting capacity, this breaker combines serious protection capabilities with a compact form factor. Its design is optimized for use in commercial, industrial, and high-load residential settings, where both safety and space efficiency matter.

Key Features and Benefits

• High load capacity in a compact design: Rated at 200 amps across two poles, it allows you to support heavy-duty circuits without requiring an oversized panel.
• 10 kA interrupting rating: Able to interrupt up to 10,000 amps at 120/240 VAC, it guards against fault currents and sudden surges.
• HACR (Heating, Air Conditioning, Refrigeration) rated: Tested for HVAC and refrigeration environments to ensure reliable operation under thermal stress.
• Load-side lugs included: Comes with factory-installed load-side lugs for simpler wiring and fewer accessory purchases.
• Designed for 40 °C ambient operation: Built to maintain performance under elevated ambient temperatures.
• Thermal-magnetic trip mechanism: Protects against both continuous overloads and instantaneous short-circuit events.
