It carries a 15 kA breaking capacity per EN 60898 and a 50 kA rating per IEC 60947-2, making it suitable for industrial branch-circuit protection where high fault currents are possible. The 0.3 A rated current is the continuous current the breaker can carry at 35 °C ambient without tripping. At elevated panel temperatures — 40 °C, 45 °C, 50 °C, 55 °C, 60 °C — the rating derates to 0.29 A, 0.28 A, 0.27 A, 0.26 A, and 0.25 A respectively. The 15 kA breaking capacity per EN 60898 covers most residential and light commercial installations; the 50 kA per IEC 60947-2 is what you rely on in an industrial panel where the prospective short-circuit current is higher. The breaker occupies 3 modular width units (54 mm) on a DIN rail, with a depth of 76 mm and an installation depth of 70 mm. It mounts in any position and uses a quick assembly system. Touch protection is built in. Compliance documentation covers IEC/EN 60898-1, IEC/EN 60947-2, and UL1077 — the UL listing is the one to verify if your panel ships to a North American site that requires UL 508A.","metaTitle":"Siemens 5SY7314-7 SENTRON MCB, 3P C 0.3A, 15/50 kA","metaDescription":"Siemens SENTRON 5SY7314-7 miniature circuit breaker, 3-pole, C-curve, 0.3 A rated. 15 kA per EN 60898, 50 kA per IEC 60947-2.

The 5SY7210-7CC is a 10 A C-curve; the 5SY7314-7 is a 0.3 A C-curve. If the panel was wired for 10 A branch circuits, dropping in a 0.3 A breaker will trip on any load above 0.3 A — the physical swap is fine, but the circuit must be re-evaluated for the lower rating."},{"question":"What compliance documentation does this brand provide for 5SY7314-7 (RoHS, REACH, UL, IEC)?","answer":"The breaker is certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL1077.
