Overview
GE SELA36AI0030 is a 3‑pole Mag‑Break molded‑case motor circuit protector from the GE Spectra RMS range. Rated 30A, 600V AC with 65kA interrupt capacity at 480V, it uses magnetic‑only trip for fast short‑circuit protection on motor feeders. Equipped with solid‑state RMS current sensing, it delivers rapid fault response. The bolt‑on mounting style fits standard low‑voltage switchgear compartments and is a common MRO spare for industrial power distribution systems.
Series
This device belongs to the GE Spectra RMS SE150 frame molded‑case circuit breaker family. SELA36AI0030 features Mag‑Break magnetic‑only trip unit, which differs from thermal‑magnetic or LSI electronic‑trip versions. Frame size, pole quantity, trip mode and rated current are fixed parameters. Exact part‑number matching is required for replacement; other Spectra RMS models cannot be directly substituted without site system assessment.
Application Fields
It provides short‑circuit protection for motor feeders in power plants, petrochemical sites, production workshops and large‑scale industrial facilities. Installed inside low‑voltage switchgear and motor control centers, it protects pumps, fans and other medium‑size industrial motors against short‑circuit damage. It cooperates with overload relays to realize complete motor protection. A failed unit will remove short‑circuit protection and raise risks of equipment burnout.
Summary
GE SELA36AI0030 is a high‑interrupt‑capacity 30A three‑pole motor circuit protector dedicated to short‑circuit isolation for industrial motor circuits. Exact model replacement must be followed during maintenance. Check connections and operating status after installation to guarantee dependable motor‑feeder protection.Tags: GE SELA36AI0030, Spectra RMS MCCB, motor circuit protector, 30A 3‑pole circuit breaker, industrial low‑voltage distribution spare parts
