Product Description
The S271-K3 is a miniature circuit breaker designed for DIN rail mounting in industrial control panels and automation enclosures. It provides dependable overcurrent protection for branch circuits and auxiliary loads, helping isolate faults and maintain system uptime. The compact form factor supports dense panel layouts and straightforward replacement in legacy ABB/ASEA Brown Boveri installations. This breaker is suited for low-voltage applications where fast trip response and clear state indication are required. Use in PLC cabinets, machine control, and distribution subcircuits where DIN rail accessories are standard. Package contents typically include the breaker module only; accessories such as terminal covers or busbar kits are not included and should be sourced separately. The S271 family is widely used but certain variants may be obsolete; verify compatibility with current standards and ratings before deployment.
