Key Features of the Siemens HQR22B200

1. Thermal-Magnetic Trip Mechanism:
   • The heart of the HQR22B200 lies in its thermal-magnetic trip mechanism. This dual protection system combines thermal elements (for overload conditions) and magnetic elements (for short circuits). As current flows through the breaker, the thermal component responds to prolonged overcurrents, while the magnetic component detects sudden surges. Together, they ensure reliable and precise tripping.
   • The thermal-magnetic trip mechanism is a hallmark of Siemens circuit breakers, providing enhanced safety and performance.
2. QR Frame Design:
   • The QR frame design offers durability and compatibility. Whether you’re retrofitting an existing panel or installing a new one, the HQR22B200 fits seamlessly.
   • Its compact size makes it suitable for various applications, from residential load centers to industrial switchboards.
