It sits in the panel protecting a single branch circuit, not a main feed. ## Interrupting Capacity — 15 kA AC, 10 kA DC Rated interrupting capacity of 15 kA at 230 VAC and 10 kA at 125 VDC. That's enough for most sub-distribution panels fed from a 100 kVA transformer or smaller — it clears a bolted fault without welding contacts. The DC rating covers control circuits on battery-backed systems or rectified supplies; 10 kA at 125 VDC is a solid figure for a 1-pole breaker this size. ## Lifecycle — Still in Current Production Lifecycle status is listed as current — this is an active, manufacturered part, not a phase-out or last-time-buy. No successor needed; it's the standard offering for this rating and curve. For BOM planning, it's a stable line item. ## Panel Fit — DIN Rail, Single Module Width Single-pole width means it takes one module slot in the enclosure. No special busbar or adapter needed for a single-pole branch; standard comb busbar works if you're ganging multiple breakers.","metaTitle":"S801C-K16 Miniature Circuit Breaker, 16A, 1-Pole, Curve K, D","metaDescription":"S801C-K16 miniature circuit breaker, 16A, 1-pole, Curve K, 230VAC/125VDC, 15kA interrupting.
