GE SGPA36AT0400

Product Overview

The GE SGPA36AT0400 is a Spectra RMS molded case circuit breaker designed for high-capacity electrical distribution and circuit protection. It is a three-pole, 400 A breaker with a maximum voltage rating of 600 VAC. The model belongs to the SG600 frame family and uses an electronic, solid-state trip system for dependable protection in demanding electrical environments.

Moreover, the SGPA36AT0400 is associated with the 100 kA interrupting-capacity version of the Spectra RMS SG600 family at 480 VAC. Its robust molded-case construction makes it suitable for industrial and commercial distribution equipment.

Technical Specifications

The published GE catalog information lists SGPA36AT0400 as a three-pole SG600 breaker for the 400 A frame and identifies it within the 100 kA product group.

Key Features

The SGPA36AT0400 provides several useful characteristics for large electrical distribution systems:

• Three-pole configuration for three-phase circuit protection.
• 400 A current rating for high-load applications.
• 600 VAC maximum voltage rating.
• High interrupting capability for demanding fault conditions.
• Digital solid-state RMS sensing technology.
• Adjustable instantaneous protection with tracking short-time functionality.
• Field-installable front-mounted rating plugs within the Spectra RMS system.
• Suitable for panelboards, switchboards, feeders, and other distribution equipment.

Construction and Protection System

The breaker combines a molded case with an electronic trip mechanism. The solid-state sensing system digitally samples electrical current and determines the RMS value of both sinusoidal and non-sinusoidal currents. Therefore, the breaker can provide more sophisticated protection than a basic thermal-magnetic design.

The three-pole configuration allows the device to protect multi-phase distribution circuits. In addition, the Spectra RMS family supports interchangeable rating plugs, allowing the applicable ampere setting to be selected within the supported range.

Applications and Maintenance

The GE SGPA36AT0400 can be used in industrial power distribution, commercial electrical systems, feeder circuits, switchboards, and large equipment power networks. Typical applications include main distribution protection, industrial feeders, service-related protection, and large motor feeder circuits.

Before installation, verify the voltage, current, interrupting rating, pole configuration, mounting arrangement, and associated accessories. The breaker should be installed by qualified electrical personnel. Regular inspection should include checking terminals, mechanical operation, enclosure condition, and signs of overheating or abnormal wear.
