Product Dimensions：

The SFLA36AI0250 is an industrial-grade molded case circuit breaker that incorporates micro-processor-based digital trip unit technology. As part of the Spectra RMS line, it uses digital sampling to continuously monitor true RMS current levels, ensuring accurate trip decisions even in the presence of harmonic distortion. The breaker features an internal frame construction that houses both the switching mechanism and the electronic trip system within a compact molded case, designed to interrupt fault currents quickly and safely.

Product Advantages

A primary advantage of the SFLA36AI0250 is its True RMS Sensing Capability, which prevents nuisance tripping caused by non-linear loads and electrical noise common in modern industrial facilities. The Compact SF250 Frame saves significant space inside switchboards, control panels, and load centers while maintaining high interrupting capacity.

Another key benefit is its Enhanced Protection Accuracy provided by the digital trip unit, ensuring precise time-current trip characteristics for superior system coordination. Additionally, the Current-Limiting Action of the contact mechanism drastically reduces thermal and magnetic stress on downstream equipment during a short-circuit event.

Important Considerations and Precautions

When installing and maintaining the SFLA36AI0250, always ensure that the entire electrical panel is Completely De-energized and Locked Out to prevent fatal electrical shock. Care must be taken to apply the Correct Terminal Torque to the lug connections as specified by GE; under-torqued lugs can cause excessive overheating, while over-torquing can strip the terminal threads or damage the breaker casing.

It is also critical to verify that the Interrupting Rating (AIC) of the breaker matches or exceeds the available fault current at the point of installation in the distribution network. Regularly inspect the molded case for cracks or signs of overheating, and ensure that the environmental conditions stay within specified temperature and humidity limits to preserve the life of the internal digital trip unit.

Product Applications

The GE SFLA36AI0250 is deployed across a broad range of industrial and commercial power distribution applications.

Commercial Power Panels: Serving as a main or feeder breaker in commercial building switchboards and distribution panelboards.
Motor Control Centers (MCC): Providing short-circuit and overload protection for high-capacity motor branch circuits.
Industrial Manufacturing Facilities: Protecting heavy machinery, transformers, and heating equipment from overcurrent damage.
HVAC Systems: Used as a protective disconnect for large industrial chillers, air handlers, and compressor units.
Critical Infrastructure: Main power feed protection in data centers, hospitals, and telecommunication facilities.
