Description
Product Name: 140G-H0H4-D16 Allen Bradley Output module
Product details:
The Allen-Bradley 140G-H0H4-D16 is a Molded Case Circuit Breaker (MCCB) designed to provide overcurrent protection for conductors and equipment in industrial power systems. It belongs to the 140G family of circuit breakers, known for their high interrupting capacity and compact size, making them suitable for global applications.
Product Parameters (Specifications)
| Parameter | Value | Notes |
| Device Type | Molded Case Circuit Breaker (MCCB) | Bulletin 140G Series |
| Frame Size | H Frame | Corresponds to a maximum frame rating (e.g., 125 A, though this breaker is rated 160 A) |
| Amperage/Current Rating | 160 Amps (A) | This is the continuous current rating (D16 in the catalog number often indicates $160 \text{A}$) |
| Number of Poles | 4-Pole | Suitable for 3-phase systems with a neutral conductor (e.g., $3P+N$) |
| Trip Type | Electronic LSI Trip | LSI stands for Long-time, Short-time, and Instantaneous protection. This offers more advanced and adjustable protection curves compared to thermal-magnetic. |
| Interrupting Capacity (kAIC) | High values (varies by voltage) | e.g., $150 \text{kA}$ at $220 \text{V}$, $120 \text{kA}$ at $415 \text{V}$, $100 \text{kA}$ at $440 \text{V}$ |
| Standard Approvals | UL, CSA, CCC, IEC | Approved for broad global use. |
Product Advantages (Key Features)
- High Interrupting Capacity: The 140G series is designed to handle high fault currents, ensuring superior protection for downstream equipment and conductors.
- Advanced Electronic Trip Unit (LSI): Provides precise and adjustable protection settings for:
- Long-time: Overload protection.
- Short-time: Protection against moderate short circuits.
- Instantaneous: Protection against severe short circuits.
- Global Compliance: Certified to major international standards (UL, CSA, IEC, CCC), simplifying inventory and application in multinational projects.
- Space-Saving Design: Features a minimal mounting footprint, allowing for higher density in control panels.
- Versatility: The 4-pole configuration makes it suitable for complex distribution systems that require switching and protection for a neutral line.
Important Considerations (Safety and Usage Notes)
- Installation: Must be installed by qualified personnel according to all local electrical codes and standards (e.g., NEC, IEC standards).
- Torque: Ensure terminal screws are torqued to the manufacturer’s specified value to prevent loose connections, overheating, and potential failure.
- Coordination: For proper system protection, the trip settings (Long-time, Short-time, Instantaneous) on the electronic trip unit must be properly coordinated with upstream and downstream protective devices (fuses, other breakers).
- Auxiliary Accessories: Check the requirement for and properly install any necessary accessories (e.g., auxiliary contacts, shunt trips, undervoltage releases) which may be factory- or field-installed.
- Operating Environment: Use within the specified environmental conditions (temperature, humidity) to ensure reliable operation and lifespan.
Product Applications (Typical Use Cases)
The Allen-Bradley 140G-H0H4-D16 is primarily used for power distribution and protection in various industrial environments:
- Main Disconnect and Feeder Protection: Used as the main circuit protection device in industrial control panels (ICPs) or as protection for a major distribution feeder line.
- Panelboard and Switchboard Protection: Installed in power distribution panelboards to protect branch circuits.
- Machinery Protection: Protecting the main power input to large industrial machinery, processing equipment, and production lines.
- Transformer Secondary Protection: Used to protect the secondary side of power transformers.
- Global Industrial Applications: Ideal for equipment destined for international markets due to its multi-standard compliance.
