QN2175 - 175Amp Circuit Breaker

QN2175 - 175Amp Circuit Breaker

The QN2175 is a 2-pole, 175-amp Type QN plug-in thermal magnetic circuit breaker designed to provide dependable overcurrent and short-circuit protection for your compatible residential main load centers. Rated for 120/240VAC with a 10kA A.I.C. interrupting capacity, this breaker helps you to protect electrical distribution systems from damage caused by overloads and fault currents while supporting safe, reliable operation. Its thermal-magnetic trip mechanism provides responsive protection against both sustained overload conditions and instantaneous short circuits, making it well-suited for your demanding residential electrical applications. Built for 40°C operation and 50/60Hz systems, the QN2175 also carries an HACR Type rating, making it suitable for approved heating, air conditioning, and refrigeration equipment. The plug-in design simplifies installation in compatible panels, while the breaker requires four panel spaces to accommodate its high current capacity. Whether you're replacing an existing breaker during maintenance or completing a panel upgrade, the QN2175 offers the performance and protection expected for high-amperage residential electrical systems.
