ABB SU201MR-K50 SU200MR Miniature Circuit Breaker, 1-Pole, 50 A, K Curve
The ABB SU201MR-K50 is a 1-pole miniature circuit breaker from the ABB SU200MR series, rated 50 A with a K tripping characteristic and a 10 kA breaking capacity. It is UL 489 listed, so it can be used for branch circuit protection in control panels, machinery and building distribution. Ring tongue terminals (RTT) accept ring cable lugs for secure connections in high-vibration equipment.
The K curve trips instantaneously at 8 to 14 x In, which makes it a strong fit for motors, transformers and other inductive loads with high inrush current. Automation Distribution supplies the SU201MR-K50 as an authorized ABB distributor.
