Product Description (Detailed Explanation)

The SELA36AI0100 belongs to the SE150 frame size within the GE Spectra RMS™ family. Unlike traditional thermal-magnetic breakers, this model utilizes True RMS sensing.

• Electronic Trip Unit: It is equipped with a digital electronic trip system that samples the current waveform to calculate the true heat energy, ensuring accurate protection even in circuits with high harmonic distortion (common in environments with VFDs and computers).

• Frame & Rating: It is a 3-pole breaker with a 150A frame size, factory-set with a 100A rating plug.

• Interchangeability: The rating plugs can be swapped within the frame size to change the continuous current rating without replacing the entire breaker.

Product Parameters (Technical Specifications)

Product Advantages (Key Benefits)

• High Accuracy: True RMS sensing prevents “nuisance tripping” caused by non-linear loads and harmonics, which often confuse standard thermal breakers.

• Flexible Protection: The electronic trip unit allows for precise adjustments, making it easier to achieve selective coordination with upstream and downstream devices.

• Compact Footprint: Offers high interrupting capacities (up to 100kA) in a relatively small frame size, saving space in electrical panels.

• Environmental Stability: Electronic trip units are less sensitive to ambient temperature fluctuations compared to traditional bi-metallic strips.

• Internal Accessory Compatibility: Supports a wide range of field-installable accessories, including shunt trips, auxiliary switches, and bell alarms.

Precautions (Important Notes)

• Proper Torque: Always use a calibrated torque wrench when tightening terminal lugs. Loose connections are the primary cause of overheating and breaker failure.

• Rating Plug Verification: Ensure the rating plug is firmly seated and matches the intended circuit load. Removing the rating plug while the breaker is energized can lead to unpredictable behavior.

• Testing: Use a primary injection test set or the specialized GE handheld test kit to verify the electronic trip curves periodically as part of a maintenance program.

• Directional Feed: While many MCCBs are bi-directional, always verify the “Line” and “Load” markings if specific internal accessories (like certain trip units) are installed.

Product Applications (Typical Use Cases)

The SELA36AI0100 is widely used in critical power infrastructure:

• Motor Control Centers (MCC): Providing branch circuit protection for industrial motors and variable speed drives.

• Commercial Buildings: Protecting main distribution boards in hospitals, data centers, and office complexes where harmonic loads are prevalent.

• Industrial Manufacturing: Serving as a main or sub-feeder breaker for assembly lines and heavy machinery.

• OEM Equipment: Integrated into custom control panels for specialized industrial equipment requiring high-reliability short-circuit protection.
