- - Allen‑Bradley 1489-A1C060 Miniature Circuit Breaker
    
    Product Overview
    
    Single-pole miniature circuit breaker of Bulletin 1489-A series, C trip curve with 6 A rated current. It offers overload and short-circuit protection for low-power branch circuits inside industrial control cabinets, widely used to guard PLC power supplies, sensors, relays, solenoid valves and other low-power control loads.
    
    Core Specifications
    
    Poles: 1-pole
    
    Rated current: 6 A
    
    Trip characteristic: C curve, suitable for inductive loads with large inrush current at startup
    
    Rated working voltage: 240 VAC / 48 VDC
    
    Short-circuit breaking capacity: 10 kA @ 240 VAC
    
    Terminal type: Screw terminals, wire range 24–12 AWG
    
    Mounting: Standard 35 mm DIN rail mounting
    
    Operating temperature: -20 ℃ ~ +60 ℃
    
    Protection mode: Thermal overload delayed trip + electromagnetic instantaneous short-circuit trip
    
    Status display: Mechanical indicator flag to show ON / OFF / tripped state
    
    Certifications: UL, cUL, CE certified; IP20 for indoor cabinet installation only
    
    Main Functions
    
    Thermal overload protection: Automatically disconnect power under long-term overcurrent to prevent cable overheating and insulation aging damage
    
    Instant short-circuit protection: Rapidly cut off power when short circuit occurs to avoid component burnout and fire hazards
    
    Manual isolation function: Act as a disconnect switch to safely cut power during equipment maintenance
    
    Protect sensitive low-voltage control equipment including switching power supplies, transmitters and auxiliary control loops
    
    Key Advantages
    
    Compact slim body saves cabinet installation space. C curve characteristic resists nuisance tripping induced by inrush current of coils and power supplies during startup. Visible mechanical trip indicator speeds up on-site fault diagnosis. Plug-in DIN rail design enables fast replacement without rewiring. Dual thermal-magnetic protection comprehensively improves branch circuit safety.
    
    Typical Applications
    
    PLC auxiliary power branch protection, power supply circuits for sensors and transmitters, relay interlock circuit protection, small fans, indicator lights and solenoid valve load protection, secondary distribution circuits inside automation control cabinets
