They share the same System pro M compact family and DIN rail mount, but the pole count difference means you can't just swap one for the other without rewiring the load side.","metaTitle":"ABB S271-NA-K8 DIN Rail Circuit Breaker, Current Production","metaDescription":"ABB S271-NA-K8 DIN rail mount circuit breaker, current production.

They share the same DIN rail mounting and System pro M compact family, but the pole count mismatch means the load wiring and busbar arrangement would need rework.
