Siemens CED63B050 Three Pole 50 Amp Circuit Breaker

Siemens CED63B050 Sentron three-pole molded-case circuit breaker protects three‑phase circuits in commercial and industrial power distribution. It is a 50 A, 600 V AC device from the CED6/ED frame family with a thermal‑magnetic trip for reliable short‑circuit protection and coordinated overload protection. The breaker delivers a 100 kAIC interrupting rating at 600 V (and 200 kAIC at 480 V, depending on voltage), with bolt‑on mounting and load‑side lug terminals for easy panel connections in a 40°C ambient environment. Typical ED‑frame dimensions place it around 4 in L × 6 in W × 10 in H, making it suitable for motor feeders, control panels, and distribution circuits in industrial facilities.
