GE SELA36AT0100 Circuit Breaker

## Product Overview

The SELA36AT0100 belongs to the Spectra RMS Hi-Break family. It is a 3-pole, 100-ampere frame breaker that utilizes a sophisticated digital RMS sensing trip unit. The "SELA" designation indicates a high interrupting capacity, making it suitable for environments with high fault current potential.

## Technical Specifications

## Key Product Advantages

• Digital Accuracy: The RMS sensing technology ensures the breaker doesn't nuisance trip due to harmonic distortion in the electrical system, providing precise protection.

• High Interrupting Capacity: With a 65kA rating at 480V, it can safely handle significant short-circuit currents, protecting downstream equipment.

• Compact Footprint: The SE150 frame size allows for high-density installation in panelboards and switchboards.

• Flexibility: It features interchangeable rating plugs, allowing the user to change the continuous current rating without replacing the entire breaker.

• Field-Installable Accessories: It supports a wide range of internal accessories, including shunt trips, auxiliary switches, and bell alarms.

## Common Applications

The SELA36AT0100 is versatile and found in various demanding environments:

• Industrial Plants: Protecting motor control centers (MCCs) and heavy machinery.

• Commercial Buildings: Main or branch protection in high-rise office distribution panels.

• Data Centers: Where high reliability and resistance to harmonic noise are critical.

• OEM Equipment: Integrated into custom power distribution units (PDUs).

## Important Precautions & Installation Notes

Warning: Electrical equipment should be installed, operated, and maintained only by qualified personnel.

1. Rating Plugs: This breaker requires a Rating Plug (e.g., SRPK100A) to function. The breaker will not close without the plug installed, and the plug must match the desired continuous current.

2. Mounting Orientation: It can be mounted vertically or horizontally without affecting the trip characteristics.

3. Torque Requirements: Ensure all terminal connections are torqued to the manufacturer’s specifications to prevent overheating.

4. Environment: Avoid installing in areas with excessive moisture, corrosive gases, or extreme dust without proper enclosures (NEMA rated).
