GE SGPA36AT0400 400A

Designed for High-Current Distribution

For electrical systems that require reliable high-current protection, the GE SGPA36AT0400 offers a practical solution within the Spectra RMS product family. This molded case circuit breaker uses a three-pole configuration and supports a 400 A frame rating. Its maximum AC voltage rating is 600 V, while published product data identifies a 100 kA interrupting capacity at 480 V.

The unit is part of the SG600 frame range. As a result, it can serve as a replacement or maintenance component in compatible GE Spectra RMS distribution assemblies.

Main Performance Data

The important characteristics can be summarized as follows:

Current capacity: 400 A
Pole configuration: 3-pole
Maximum AC voltage: 600 VAC
Frame family: SG600
Breaker technology: Electronic solid-state molded case design
Interrupting rating: 100 kA at 480 VAC
Product family: Spectra RMS
Connection style: Bolt-on

These specifications are supported by GE-related catalog and distributor documentation.

Electronic Trip Technology

One of the notable aspects of the Spectra RMS platform is its digital solid-state RMS sensing system. Instead of relying only on conventional thermal behavior, the trip system uses digital sampling to evaluate current. This design allows the protection system to respond to both sinusoidal and non-sinusoidal current waveforms.

In addition, adjustable instantaneous protection with tracking short-time operation is a standard feature across the applicable Spectra RMS frames. The front-mounted rating plug arrangement also provides flexibility when establishing the applicable breaker ampere rating.

Mechanical Configuration

The SGPA36AT0400 is built as a molded case circuit breaker for high-capacity distribution equipment. Its three-pole design is intended for three-phase circuits, while the bolt-on configuration supports installation in compatible electrical assemblies.

The overall protection package combines the molded enclosure, current-sensing components, electronic trip system, operating mechanism, and connection points. Together, these elements provide a compact protection device for electrical distribution applications.

Where It Can Be Used

This GE breaker is suitable for a variety of commercial and industrial power systems. Common uses include:

• Main and feeder circuit protection
• Industrial distribution panels
• Commercial switchboards
• Large electrical equipment
• Three-phase feeder circuits
• Motor-related distribution systems
• Electrical retrofit and replacement projects

The product is specifically categorized for electrical distribution and control applications.

Installation, Inspection and Supply

Correct installation is important for safe and dependable operation. Before replacing an existing breaker, verify the electrical system voltage, required current rating, pole count, interrupting capacity, mounting arrangement, and compatible accessories. Connections should be properly secured according to the applicable installation requirements.

Furthermore, periodic inspection can help identify loose connections, overheating, mechanical damage, or abnormal operating conditions. If the breaker shows signs of damage or malfunction, qualified electrical personnel should evaluate it before returning the circuit to service.
