QDM22175TN - 175 Amp Circuit Breaker

QDM22175TN - 175 Amp Circuit Breaker

The QDM22175TN is a 2-pole, 175-amp thermal magnetic circuit breaker with a fixed, non-interchangeable thermal magnetic trip unit. It helps protect electrical equipment by opening the circuit during overloads and short circuits before damage can occur. Rated for 25kA at 240VAC, this breaker is commonly used in commercial and industrial power distribution systems where higher interrupting capacity is required. This model features line-side lug terminals for incoming conductors and 1/4-20 stud terminals on the load side, making it a practical choice for equipment that requires this connection style. If you're replacing an existing QDM breaker or maintaining compatible switchgear or panel equipment, the QDM22175TN offers the electrical ratings and connection configuration needed for a straightforward installation.
