HS code：8517623990

Product Details：

Product Dimensions：

The SGLA36AT0400 is a 3-pole, 600-ampere frame circuit breaker that utilizes an electronic trip system. The Spectra RMS breakers are known for their compact size and high interrupting capacity. Unlike traditional thermal-magnetic breakers, this electronic version provides more precise and adjustable protection settings. The unit is designed for use with interchangeable rating plugs, allowing the user to set the continuous current rating without replacing the entire breaker.

Product Advantages

One of the primary advantages of the SGLA36AT0400 is its Electronic Trip Precision. The solid-state technology ensures consistent performance regardless of ambient temperature fluctuations, which can often cause "nuisance tripping" in thermal-magnetic breakers.

The Interchangeable Rating Plug system offers incredible flexibility; you can change the breaker’s amperage rating simply by swapping a small plug in the front of the unit, which is highly cost-effective for future system upgrades. Additionally, the High Interrupting Capacity allows it to be installed in systems with high available fault currents, ensuring the safety of downstream equipment. Its compact frame design also saves significant space within electrical panels and motor control centers.

Important Considerations and Precautions

Before installation, verify that the Interrupting Rating of the breaker is equal to or greater than the available fault current at that point in the electrical system to prevent catastrophic failure during a short circuit.

Ensure the Rating Plug is securely seated; the breaker will not function correctly or may trip immediately if the plug is missing or improperly installed. Always perform a mechanical "push-to-trip" test after installation to ensure the internal mechanism moves freely. Because this is an electronic breaker, avoid using high-voltage insulation testers (Meggers) directly on the load side without disconnecting the electronic trip unit, as the high voltage could damage the sensitive internal microprocessors.

Product Applications

The GE SGLA36AT0400 is a versatile protective device found in a variety of critical environments:

Commercial Buildings: Used in main distribution panels for office complexes, hospitals, and high-rise apartments to protect HVAC systems and lighting circuits.
Industrial Manufacturing: Protecting heavy machinery, large motors, and production lines where high inrush currents are common.
Data Centers: Providing reliable power distribution to server racks where uptime is critical and precise trip settings are needed to prevent widespread outages.
Infrastructure: Utilized in water treatment facilities and transportation hubs for control and protection of pumping stations and auxiliary power systems.
