Description
Product Name: 140G-H15I3-D16 Allen Bradley Output module
Product details:
The Allen-Bradley 140G series Molded Case Circuit Breakers (MCCBs) are designed to provide circuit protection in industrial and commercial applications. The part number 140G-H15I3-D16 structure indicates the following:
| Code Segment | Description | Likely Interpretation |
| 140G | Product Series | 140G Molded Case Circuit Breaker |
| H | Frame Size | H-Frame (Typically associated with a higher amperage range, e.g., up to 150 A or 250 A) |
| 15 | Amperage Rating | May indicate the maximum current rating of the frame (e.g., 150 A or 250 A) |
| I | Interrupting Rating | Indicates a specific level of short-circuit interrupting capacity (e.g., Standard, High, or Very High). |
| 3 | Number of Poles | 3-Pole (for three-phase circuits) |
| D16 | Trip Unit Rating | Indicates the specific continuous current rating of the trip unit, likely 160 A (160 Amps) |
Estimated Product Parameters (Based on 140G H-Frame)
| Parameter | Estimated Value/Range |
| Product Type | Molded Case Circuit Breaker (MCCB) |
| Frame Size | H-Frame |
| Number of Poles | 3-Pole |
| Rated Current ($I_n$) | 160 Amps (A) |
| Rated Operational Voltage ($U_e$) | Up to 690V AC (Voltage tolerance is market-dependent) |
| Rated Insulation Voltage ($U_i$) | Typically 750V or 1000V AC |
| Interrupting Capacity ($I_{cu}$) (kA) | Varies depending on the ‘I’ code, often in the range of 35kA to 100kA at 400/415V AC. |
| Trip Unit Type | Typically Thermal-Magnetic or Electronic (Microprocessor-based). The ‘D’ in D16 often suggests an Adjustable Thermal, Fixed Magnetic trip unit. |
| Trip Functions | Overload protection (Thermal), Short-Circuit protection (Magnetic) |
| Mounting | Panel/Backplate Mount |
Product Advantages (General for 140G MCCBs)
- High Interrupting Capacity: Designed to safely interrupt high short-circuit currents, ensuring system and personnel safety.
- Modular and Compact Design: Saves panel space and facilitates easier installation and maintenance.
- Wide Range of Accessories: Compatibility with auxiliary contacts, shunt trips, undervoltage releases, and motor operators for enhanced control and monitoring.
- Flexibility in Protection: Available with both thermal-magnetic and electronic trip units, allowing for precise and adjustable overload and short-circuit settings.
- Global Standards Compliance: Designed to meet major international standards (e.g., IEC, UL, CSA), making them suitable for global use.
- Coordination Capabilities: Engineered for selective coordination with downstream devices, minimizing power outages to affected sections only.
Precautions (Important Considerations)
- Proper Sizing: The MCCB must be correctly sized based on the maximum continuous load current and the available short-circuit current at the point of installation. Do not exceed the 160A trip rating.
- Interrupting Rating Check: Ensure the MCCB’s Interrupting Capacity ($I_{cu}$) is equal to or greater than the maximum potential short-circuit current at the installation location.
- Torque Specifications: Always follow the manufacturer’s specified torque values for terminal connections. Loose connections can lead to overheating, arcing, and failure.
- Use Approved Accessories: Only use Allen-Bradley/Rockwell Automation approved accessories (e.g., terminal shields, lugs, trip units) to ensure proper fit and performance.
- De-rating: MCCBs may need to be de-rated (operated below their nominal rating) in high ambient temperature environments or when multiple breakers are mounted in close proximity. Consult the product manual’s de-rating curves.
- Safety Procedures: Always de-energize and lock-out/tag-out (LOTO) the circuit before performing any installation, wiring, or maintenance work on the MCCB.
Product Applications
The 140G-H15I3-D16 MCCB is primarily used for protection and control in various three-phase industrial electrical systems:
- Main/Sub-Main Panel Protection: Used as the primary disconnecting means and overcurrent protection for entire electrical distribution panels.
- Feeder Circuit Protection: Protecting heavy-duty branch circuits that supply power to large equipment.
- Motor Protection: Used in conjunction with contactors/starters to provide thermal and short-circuit protection for high-horsepower three-phase motors.
- Transformer Secondary Protection: Protecting the secondary side of power transformers from overload and short-circuit conditions.
- Load Center Protection: Providing power distribution and protection in machinery and equipment enclosures.
- Commercial Buildings: Used in HVAC, lighting, and general power distribution systems requiring robust circuit protection.
