Siemens CLF63S250A Molded Case Circuit Breaker

Siemens CLF63S250A Molded Case Circuit Breaker is a three‑pole MCCB rated for 250 A at up to 600 V AC, designed to provide reliable overcurrent protection for feeders and branch circuits in commercial and industrial power‑distribution panels. The catalog number CLF63S250A identifies a Siemens device in the legacy I‑T‑E/Sentron molded‑case breaker family, intended for use in 3‑phase systems where compact protection is required within a low‑voltage distribution scheme. In the Siemens 63‑series lineage, closely related models such as CFD63S250A and FXD63S250A share the same 3‑pole, 250 A, 600 V specification and are documented with a 100 kA short‑circuit interrupt rating, illustrating the performance class commonly associated with this frame size. For installations needing a proven 600 V protection solution within Siemens’ protection portfolio, the CLF63S250A provides a standard MCCB option that integrates with Siemens low‑voltage distribution practices and follows conventional trip characteristics found in the broader Sentron MCCB lineup.
