Siemens Industry, Inc. HDX3B060 Circuit Breaker

The Siemens HDX3B060 is a three-pole molded-case circuit breaker built to guard 3-phase electrical feeders in industrial and commercial power systems. With a continuous current rating of 60 A and a maximum operating voltage of 600 V, it protects downstream equipment from overloads and short circuits while fitting into standard Siemens distribution panels. The unit carries a 20 kA interrupting rating, enabling it to safely break fault currents at system voltage and help limit damage during faults. As part of Siemens' HDX family, the HDX3B060 employs thermal-magnetic protection to respond to both overload conditions and short-circuit events, offering a compact, robust solution for motor feeders, panelboards, MCCs, and other 3-phase distribution applications. This molded-case breaker is designed for easy integration in 3-phase circuits requiring reliable, fast interruption of fault currents and straightforward field replacement in compatible Siemens environments.
