Siemens QJ23B060 3 Pole Molded Case Circuit Breaker

Siemens QJ23B060 is a three-pole molded‑case circuit breaker rated for 60 A at 240 V, designed to protect distribution feeders in industrial and commercial panels. It belongs to the QJ/QJ2 family (QJ2 frame) and employs a thermal‑magnetic trip with an interrupt rating of 10 kA at 240 V, enabling protection against high‑fault currents. The unit is bolt‑on mounted and, for this variant, features load lug terminals for straightforward wiring connections. With its 60 A rating, 240 V operation, 10 kA interrupt rating, and robust MCCB construction, it is a common choice for mid‑sized feeder protection in panelboards and switchgear assemblies.
