ABB SU201M-K6 Miniature Circuit Breaker, UL 489, K Curve

ABB SU201M-K6 is a miniature circuit breaker in the System pro M compact SU200 M family. It provides 1-pole, 6 A overcurrent protection with a K tripping characteristic for branch circuits. The design supports panel, control cabinet, and distribution applications where compact DIN-rail protection is required. 

- Thermal and electromagnetic releases respond to overload and short-circuit conditions for branch circuit protection.
- K characteristic provides instantaneous tripping in the 10 x In to 14 x In range.
- Current-limiting operation reduces let-through energy during fault events.
- Real contact position indication shows red for ON and green for OFF for direct status visibility. 

- Rated current is 6 A in a 1-pole configuration. 
- Rated operational voltage is 230 V AC under IEC data, with UL/CSA maximum operating voltage of 277 V AC and 48 V DC for 1-pole use. 
- Interrupting rating is 10 kA under UL 489, while IEC/EN 60947-2 breaking capacity is listed up to 15 kA. 
- DIN-rail mounting, double-clamp terminals, and conductor capacity up to 35 mm² rigid support compact panel installation. 

- Branch circuit protection in UL 489 electrical assemblies. 
- AC and DC control panel protection in North American and global installations. 
- DIN-rail distribution and machine panel builds requiring compact single-pole overcurrent protection.
