Description

Product Name: 140MG-H8E-D10-KA  Allen Bradley Processor module

Product details:

The Allen-Bradley 140MG-H8E-D10-KA is a high-break Motor Protection Circuit Breaker (MPCB) from the Bulletin 140MG series. It’s designed to provide comprehensive protection for motor branch circuits. This single device integrates multiple functions, including motor disconnecting, manual on/off switching, and protection against overloads and short circuits.

Technical Specifications

• Product Type: Motor Protection Circuit Breaker (MPCB)
• Frame Size: H-Frame
• Rated Current: 100 Amps
• Number of Poles: 3
• Protection Type: Thermal-Magnetic (Adjustable Thermal, Fixed Magnetic)
• Voltage Rating: 480V AC
• Interrupting Rating: 35 to 65 kA at 480V AC
• Factory-Installed Options: 1 Auxiliary Contact (KA)
• Auxiliary Contact Rating: 250V AC/DC
• Mounting: Panel-mounted

Key Advantages

• Integrated Protection: Combines disconnect, overload, and short-circuit protection into a single, compact device, simplifying motor control systems and reducing panel space.
• Adjustable Thermal Trip: The adjustable thermal trip setting allows for precise configuration to match the specific characteristics of the motor, ensuring reliable overload protection.
• High Interrupting Capacity: With an interrupting rating of up to 65 kA, it is suitable for use in high-fault current environments, providing robust protection.
• Simplified Installation: The KA suffix indicates that the auxiliary contact is factory-installed, which saves time and effort during wiring and setup.
• Manual Operation: It provides a manual means of switching a motor on and off, which is essential for maintenance and troubleshooting.

Important Considerations

• Proper Sizing: Always select the MPCB with the correct amperage rating and trip range for your specific motor application to ensure adequate protection.
• Installation: Installation should be performed by a qualified professional in accordance with all local and national electrical codes.
• Ambient Temperature: The performance of thermal-magnetic circuit breakers can be affected by ambient temperature. Consult the manufacturer’s documentation for derating curves and guidelines.
• Accessories: While this model includes a factory-installed auxiliary contact, additional accessories like shunt trips or undervoltage releases may be available separately for specific control requirements.

Typical Applications

The Allen-Bradley 140MG-H8E-D10-KA is ideal for a wide range of industrial applications, including:

• Individual Motor Control: Providing a complete protection solution for single-motor applications.
• Motor Starter Combinations: Used as the primary branch-circuit protection device in combination with a contactor to create a motor starter.
• Industrial Machinery: Protecting motors in pumps, compressors, fans, conveyors, and other machinery.
• Control Panels and Cabinets: Providing a compact and efficient solution for motor protection within industrial control panels.
