SGLA36AT0400 GE FANUK

SGLA36AT0400 GE Fanuc Power Board

Product  Description：

The GE SGLA36AT0400 is a 3-pole, 600-volt maximum circuit breaker designed for use with the Spectra RMS series. The "SG" signifies the frame size, which is one of the larger and more robust frames in the Spectra line. This specific unit is a "line-side" or "load-side" interchangeable breaker that utilizes a digital, solid-state trip system. This means that instead of relying on traditional thermal-magnetic strips, it uses internal current transformers and a microprocessor to sense overcurrent conditions, allowing for much greater precision and adjustability.

Product Parameters

The technical specifications for this model define its capacity and operational limits within a power system:

• Frame Type: SG Frame (Spectra RMS Series)

• Number of Poles: 3 Poles

• Amperage Rating: 400 Amperes (Maximum Continuous Current)

• Voltage Rating: 600 VAC (Volts Alternating Current)

• Interrupting Rating: 65 kA at 480 VAC / 100 kA at 240 VAC

• Trip Unit Type: MicroVersaTrip Plus or PM (Electronic/Solid-State)

• Standard Functions: Long Time (L), Instantaneous (I), and often Short Time (S) or Ground Fault (G) depending on the specific trip unit configuration.

• Frequency: 50/60 Hz

• Connection: Bolt-on design for use in switchboards, panelboards, or individual enclosures.

Product Advantages

One of the primary advantages of the SGLA36AT0400 is its Digital Precision. Because it uses electronic trip units, it offers highly accurate time-current curves, which helps in achieving better coordination with upstream and downstream devices. The Interchangeability of the rating plugs is another major benefit; you can change the continuous current rating of the breaker simply by swapping a small plug in the front, rather than replacing the entire heavy breaker.

The High Interrupting Capacity (65kA at 480V) makes it suitable for heavy industrial environments where high short-circuit currents are a risk. Furthermore, the Compact Footprint of the SG frame allows for high-density power distribution within electrical closets and motor control centers without sacrificing safety or performance.

Important Considerations and Precautions

When installing or maintaining the SGLA36AT0400, strictly follow these safety guidelines:

• De-energize Equipment: Never attempt to install or remove this circuit breaker while the bus or line side is energized. Arc flash hazards can cause severe injury or death.

• Torque Requirements: All electrical connections must be tightened to the specific torque values provided by GE. Loose connections lead to overheating, which can cause nuisance tripping or fire.

• Rating Plug Verification: Ensure the rating plug installed in the trip unit matches the desired protection level. The breaker will not function correctly if the rating plug is missing or improperly seated.

• Environmental Limits: While the MCCB is rugged, it should be mounted in an enclosure that protects it from conductive dust, corrosive vapors, and excessive moisture, which can degrade the electronic trip unit.

• Testing: Periodic primary or secondary injection testing is recommended to ensure the electronic trip unit is functioning according to its programmed curves.

Product Applications

The GE SGLA36AT0400 is a versatile component found in a wide range of power distribution applications:

• Industrial Manufacturing: Used as a main or branch breaker in motor control centers (MCCs) and distribution panels to protect heavy machinery and production lines.

• Commercial Buildings: Ideal for providing service entrance protection or protecting large HVAC systems and lighting loads in high-rise buildings and shopping centers.

• Data Centers: Providing reliable power distribution to server racks where precision tripping is required to prevent unnecessary downtime of critical IT infrastructure.

• Healthcare Facilities: Used in hospital power systems to ensure selective coordination, ensuring that a fault in one wing does not shut down power to the entire facility.

• Infrastructure: Found in water treatment plants and pumping stations for protecting large-scale pump motors and control equipment.
