Siemens QR Circuit Breakers
Siemens QR circuit breakers have compact housing. They are equipped to handle high inrush currents and interrupt ratings, and they support internal accessories that can be field-installed. QR circuit breakers are frequently used in panelboards, power panels, load centers, meter centers, and switchboards. They can operate without derating at ambient temperatures of up to 40 degrees Celsius (104 degrees Fahrenheit). The QR circuit breakers series includes 2-pole and 3-pole breaker models. Many models also support reverse feed features and push-to-trip buttons. Some QR circuit breakers can support maximum interrupt ratings of 100 kA.
