The Siemens 5SP4380-7 is a SENTRON 5SP miniature circuit breaker — 3-pole, C-curve, 80 A rated current at 400 V AC, with a 10 kA breaking capacity certified to EN 60898.
IP20 with connected conductors, IP40 at the handle area with a distribution cover — fine for a dry indoor panel.
10 kA per EN 60898 at 400 V AC. That's the standard residential and light-commercial fault level — adequate for most panelboards and sub-distribution boards.
Sourced and quoted to order against an RFQ through independent distribution. Availability and current pricing are confirmed at quote time — submit an RFQ for a firm number.
Both are 3-pole SENTRON 5SP breakers with the same 4.5 MWU footprint and DIN-rail mounting — same mechanical envelope. The difference is rating: 5SP4380-7 is 80 A C-curve; 5SP4292-7 is a different current/curve. If the panel bus and load side are sized for 80 A, it swaps in without rewiring.
