Product Description

The GE SELA36AI0100 belongs to the SE150 Frame of the Spectra RMS family. Unlike standard thermal-magnetic breakers, this “AI” (Instantaneous-only) version provides only magnetic short-circuit protection. It is used in combination with an overload relay to provide a complete motor branch circuit protection solution.

Product Parameters

Product Advantages

• Current Limiting: The “L” in SELA designates it as a current-limiting breaker, which rapidly clears faults to protect downstream equipment from high energy “let-through.”

• True RMS Sensing: Uses digital sampling to accurately measure the RMS value of current, ensuring reliable operation even in systems with high harmonic distortion.

• Interchangeable Rating Plugs: Allows for field adjustments of the ampere rating without replacing the entire breaker frame.

• Compact Footprint: The SE150 frame provides a high interrupting capacity in a space-saving design, making it ideal for compact motor control centers (MCCs).

• Reverse Feed Capable: Suitable for reverse-fed applications, increasing installation flexibility.

Product Applications

• Motor Control Centers (MCC): Primarily used as a Motor Circuit Protector (MCP) to provide high-speed short-circuit protection for individual motor branches.

• Industrial Machinery: Protecting sophisticated motor-driven equipment where high fault currents are possible.

• Harmonic-Rich Environments: Ideal for systems with non-sinusoidal loads (like VFDs) due to its digital RMS sensing technology.

Important Precautions

• NEC Compliance: Per National Electrical Code (NEC), magnetic-only breakers like the SELA36AI0100 must be used in a listed combination starter with a separate overload protection device. They cannot be used as a standalone branch circuit breaker.

• Lugs Requirement: Standard units are often sold without lugs (Lugs Not Included). Ensure you specify the correct lug kit (e.g., TCAL18) for your wire type (Copper or Aluminum).

• Instantaneous Settings: Carefully calculate the motor’s inrush current when setting the instantaneous trip dial to prevent nuisance tripping during motor startup.

• Environmental Limits: Ensure the operating temperature does not exceed the rated 40°C (104°F) without proper derating.
