The Siemens 5SY4114-8CC11 is a 1-pole miniature circuit breaker rated at 230/400 V with a 10 kA breaking capacity, a D tripping curve, and a 0.3 A current rating, specifically designated for railway applications.
Deployment context
Snaps onto standard 35 mm DIN rail inside a railcar or trackside enclosure; the 1-pole width (roughly 18 mm per module) keeps panel fill-factor tight for multi-circuit protection.
Lifecycle and sourcing reality
For a BOM freeze or a line-down replacement, the 5SY4114-8CC11 is sourced and quoted to order against an RFQ; availability and current pricing are confirmed at quote time.
