- - Allen‑Bradley 1489-A1C130 Miniature Circuit Breaker
    
    Product Overview
    
    This is a single-pole miniature circuit breaker belonging to Bulletin 1489-A series, featuring C trip curve and 13 A rated current. It provides overload and short-circuit protection for medium-power branch circuits inside industrial control cabinets, protecting control transformers, small drives, solenoid banks and other inductive industrial loads.
    
    Core Specifications
    
    Number of poles: 1-pole
    
    Rated nominal current: 13 A
    
    Trip characteristic: C curve, designed for inductive loads with high startup inrush current
    
    Rated operational voltage: 240 VAC / 48 VDC
    
    Short-circuit breaking capacity: 10 kA at 240 VAC
    
    Terminal design: Screw terminals, compatible with 24–12 AWG copper wires
    
    Mounting method: Standard 35 mm DIN rail
    
    Operating ambient temperature: -20 ℃ ~ +60 ℃
    
    Protection mechanism: Dual thermal-magnetic protection; thermal delayed trip for overloads, electromagnetic instant trip for short circuits
    
    Status feedback: Mechanical visual flag to identify ON, OFF or tripped status
    
    Certifications: UL, cUL, CE certified; IP20 rating for indoor cabinet installation only
    
    Main Functions
    
    Overload protection: Automatically disconnect the circuit under sustained excess current to stop cable overheating and insulation damage
    
    Short-circuit protection: Instantly cut power during short-circuit faults to prevent component burnout and fire risks
    
    Manual isolation switch: Can fully isolate branch power for safe equipment maintenance and wiring modification
    
    Safeguard medium-power control loads such as control transformers, multiple solenoid valves and small auxiliary motor fans
    
    Key Advantages
    
    Slim compact housing minimizes cabinet space occupation. C curve trip performance avoids unintended tripping caused by high inrush from coils and transformers during startup. Visible trip indicator allows quick on-site fault identification. Plug-on DIN rail structure supports rapid replacement without rewiring. Integrated dual thermal-magnetic protection delivers full-range safety protection for branch circuits.
    
    Typical Applications
    
    Control transformer branch protection, multi-solenoid valve control circuits, auxiliary fan and small pump load protection, secondary distribution loops in automation panels, medium-power auxiliary control circuits for packaging and material handling equipment
