Description
Product Name: 1489-AAHH3 Allen Braley Input module
Product details:
The Allen-Bradley 1489-AAHH3 is a high-performance, AC miniature circuit breaker (MCB) designed for branch circuit protection. As part of the 1489 series, these units are specifically engineered to provide robust protection against overloads and short circuits in industrial environments.
Product Specifications
The 1489-AAHH3 is a specialized unit within the Bulletin 1489 line. Below are the core technical parameters:
| Parameter | Specification |
| Product Series | Bulletin 1489-M |
| Poles | 1-Pole (Single Pole) |
| Continuous Ampere Rating | 3 A |
| Interrupt Capacity | 10 kA (per UL 489 / CSA 22.2 No. 5) |
| Voltage Rating | 480Y/277V AC |
| Trip Curve | Type D (High inrush current protection) |
| Frequency | 50/60 Hz |
| Mounting | DIN Rail (35mm) |
| Operating Temperature | -25°C to +55°C (-13°F to 131°F) |
Key Features & Product Advantages
- UL 489 Listing: Unlike supplementary protectors (UL 1077), the 1489 series is UL 489 listed, meaning it is rated for branch circuit protection.
- High Inrush Handling (Type D): The Type D trip curve is specifically designed for loads with high inductive surges, such as motors and transformers, preventing nuisance tripping.
- Current Limiting: These breakers are designed to be current-limiting, significantly reducing the energy passed through to the circuit during a fault.
- Finger-Safe Design: Features IP20 terminals to protect personnel from accidental contact with live parts.
- Visual Status Indicator: Includes a clear window showing “Red” for ON and “Green” for OFF, ensuring easy maintenance and troubleshooting.
- Global Compliance: Meets UL, CSA, and CE standards, making it suitable for machinery exported worldwide.
Important Considerations (Precautions)
- Environmental Derating: If operating in temperatures consistently above 40°C or in high-altitude environments, the current rating must be derated according to Rockwell Automation’s technical tables.
- Proper Orientation: While they can be mounted in various orientations, ensure there is adequate ventilation and that the DIN rail is securely grounded.
- Terminal Torque: Always use a calibrated torque wrench to tighten terminals to the manufacturer-specified value (typically around 2.8 N·m or 25 lb·in) to prevent overheating.
- AC vs. DC: Ensure you are using this model for AC applications. While some 1489 models are dual-rated, always verify the specific “AAHH3” datasheet for DC voltage limits.
Typical Applications
The 1489-AAHH3 is commonly used in industrial control panels where space is a premium but high protection levels are required:
- Solenoids and Valves: Protecting the small-scale inductive loads common in pneumatic and hydraulic systems.
- Transformers: Ideal for the primary or secondary side of control power transformers where high inrush currents are expected.
- Motor Control Circuits: Providing branch protection for small motor starters or variable frequency drive (VFD) input circuits.
- Heating Elements: Reliable protection for resistive loads in industrial ovens or heaters.
