Rated 25 A at 30 °C and 400 V AC, 50 Hz, with a 6 kA breaking capacity per EN 60898 and IEC 60947-2.
Rated current is temperature-dependent: 25 A at 30 °C, derating to 24 A at 40 °C, 23.5 A at 45 °C, 23 A at 50 °C, 22.5 A at 55 °C, 22 A at 60 °C, and 21 A at 70 °C. In a warm panel (40–50 °C ambient), expect to size the circuit at 23–24 A continuous load.
Submit an RFQ; the part is sourced to order through independent distribution, with pricing and stock confirmed at quote time.
The evidence does not document a direct functional equivalence between 5SU1346-6FP25 and 5SY4301-7CV. Verify terminal layout and residual current function before substituting.
The listed depth is 72 mm, with an installation depth of 70 mm.
The width is 72 mm, corresponding to 4 modular width units (18 mm each).
Not without verification — the evidence does not confirm terminal layout compatibility between these two models. Check the wiring diagram before installation.
The part is rated per EN 60898 and IEC 60947-2. The evidence does not list specific RoHS, REACH, or UL certifications; request documentation from the supplier at quote time.
