GE SELA36A10030 Molded Case Circuit Breaker

Product Dimensions：

The GE (General Electric / ABB) SELA36A10030 (often stylized in catalogs as SELA36AI0030) is a high-performance Spectra RMS™ Series Mag-Break Motor Circuit Protector (MCP). It is a magnetic-only, molded case circuit breaker frame designed specifically for short-circuit protection in motor branch circuits.

Product Detailed Description

The SELA36A10030 belongs to the GE SE-Frame (150 Amp Max Frame) family. It features a digital, solid-state RMS sensing trip system. As a Mag-Break MCP, it does not contain a thermal overload element; instead, it provides instantaneous short-circuit protection only. It is engineered to operate in series with a separate thermal overload relay or variable frequency drive (VFD) that handles routine motor overload protection.

The unit utilizes front-mounted, field-installable rating plugs (such as the SRPE30A) to establish the continuous current rating.

Technical Parameters

Product Advantages

• Current-Limiting Design: Drastically reduces the amount of destructive let-through peak current and energy delivered to downstream components during a fault, maximizing equipment lifespans.

• True RMS Sensing: The internal solid-state electronic trip system utilizes digital sampling to calculate accurate RMS values, preventing nuisance tripping caused by harmonic distortion or non-sinusoidal currents.

• Flexible Tracking: Features an adjustable instantaneous trip setting with tracking short-time functionality, providing tailored protection to match a motor’s specific inrush current profile.

• Space-Efficient Integration: The compact SE-Frame bolt-on configuration integrates easily into standard Spectra Series panelboards and motor control centers (MCCs).

• Reverse-Feed Capable: Can be wired from line-to-load or load-to-line, giving panel builders high installation flexibility.

Important Considerations & Precautions

• No Overload Protection: Because this is a Magnetic-Only device, it will never trip on a standard motor overload (e.g., a jammed conveyor causing a mild current rise). It must be paired with a dedicated motor overload relay or VFD to fulfill NEC code requirements.

• Missing Terminals: This catalog number represents a frame-only unit. External mechanical lugs (such as model TCAL18) must be purchased separately to connect your field wiring.

• AC Voltage Only: This device is rated exclusively for AC networks. Do not apply it to DC motor control applications.

• Rating Plug Dependencies: The electronic trip capability depends on the presence of a matching Spectra rating plug inserted into the front face. Do not attempt to energize the system without the proper rating plug installed.

Product Applications

The SELA36A10030 is optimized for commercial and heavy industrial motor branch circuits:

• Motor Control Centers (MCCs): Used as the primary short-circuit protective device inside motor starter buckets.

• Industrial Automation Panels: Protecting branch circuits feeding 3-phase machinery, large exhaust fans, and industrial pumps.

• HVAC Chiller Units: Safeguarding internal compressor motor circuits when paired with external thermal protection.

• Conveyor & Material Handling: Integrated into panels where motors experience rapid start-stop cycles or high dynamic loads.
