The Siemens 5SN6103-8CP is a 1-pole miniature circuit breaker from the SENTRON 5SN series, rated for 400 V AC supply voltage with a 6 kA breaking capacity per EN 60898 and a 30 kA rating per IEC 60947-2. It also handles 72 V DC maximum, so it covers control-circuit DC rails as well. The solid conductor cross-section accepts up to 35 mm², sized for feeder or sub-feed protection in a panel.
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 price and lead-time estimate.
Rated 6 kA per EN 60898 and 30 kA per IEC 60947-2. The 30 kA IEC figure governs industrial panel coordination for branch-circuit protection.
Yes — both are 1-pole, 1-modular-width (18 mm) SENTRON MCBs with identical footprint (76 mm depth, 90 mm height, 70 mm installation depth) and snap onto standard DIN rail. No panel rework needed for fit.
As a SENTRON series MCB, it carries approvals per EN 60898 and IEC 60947-2. Standard Siemens documentation includes CE declaration, RoHS/REACH compliance statements, and the product datasheet with rated characteristics.
