- Description 1489-M2C200 A-B Miniature Circuit Breaker Product Dimensions： Product Description (Detailed Explanation) The 1489-M2C200 is a 2-Pole, 20-Ampere circuit breaker featuring a C-Trip Curve. Unlike standard supplementary protectors, the 1489-M series is UL 489 Listed, meaning it is approved for “Branch Circuit Protection.” This allows it to be used as the primary protection for internal circuits, including outlets, motors, and transformers within a control panel. The “C” trip curve is designed to handle moderate inrush currents, making it ideal for general-purpose industrial applications. It operates using a thermal-magnetic mechanism: the thermal element protects against long-term overloads, while the magnetic element provides instantaneous protection against high-magnitude short circuits. Product Parameters (Technical Specifications) Parameter Category Specification Product Series 1489-M Number of Poles 2-Pole Rated Current ($I_n$) 20A Trip Curve Type C (Magnetic trip 5…10 x $I_n$) Voltage Rating 480Y/277V AC; 96V DC (2-Pole in series) Interrupting Capacity 10 kA (UL/CSA); 15 kA (IEC) Standard Compliance UL 489, CSA C22.2 No. 5, EN/IEC 60947-2 Mechanical Life 20,000 Operations Terminal Type Finger-safe screw terminals (IP20) Mounting 35mm DIN Rail Product Advantages (Key Benefits) Dual Ratings: Fully rated for both AC and DC applications, reducing the variety of spare parts needed in a facility. UL 489 Listing: Permits its use as a branch circuit protector, providing a higher level of safety and code compliance compared to UL 1077 supplementary protectors. Current Limiting: High-speed switching action limits the let-through energy ($I^2t$) during a fault, protecting downstream components from thermal stress. Compact Design: Saves valuable DIN rail space in high-density control cabinets. Finger-Safe Terminals: Designed with IP20 protection to prevent accidental contact with live parts during maintenance. Visible Trip Status: Features a clear indicator window (Red/Green) to show the contact position at a glance. Precautions (Important Notes) Trip Curve Selection: Ensure a “C” curve is appropriate for your load. For high-surge loads like large transformers, a “D” curve may be required to prevent nuisance tripping. Torque Requirements: Use a calibrated torque screwdriver when tightening terminals. Loose connections cause localized heating, which can lead to premature tripping or fire hazards. Environmental Derating: If installing in high-temperature environments (above 40°C), the current rating must be derated according to the manufacturer’s technical charts. Orientation: While it can be mounted horizontally or vertically, ensure there is sufficient clearance above and below the breaker for arc gas venting during a short-circuit event. Product Applications (Typical Use Cases) Industrial Control Panels: Protecting branch circuits that power sensors, PLCs, and HMI units. Motor Control Circuits: Providing short-circuit protection for small motor branches where the inrush is within the C-curve limits. HVAC Systems: Used in industrial air conditioning and ventilation control units for overcurrent protection. Power Supplies: Protecting the input side of AC-to-DC switching power supplies. Infrastructure: Used in lighting circuits and power outlets within industrial facilities or data centers.
