Description
1. At-A-Glance Executive Brief
- Model: SELA36AI0030
- Brand: GE (General Electric)
- Part Type: Spectra RMS Molded Case Circuit Breaker (MCCB)
- Lifecycle Status: Mature / Legacy Distribution Support
- System Compatibility: GE Spectra Series Switchboards and Panelboards
- Weight: 1.8 kg
2. Technical Introduction
- Problem: Aging power distribution panels face catastrophic arc flash hazards and nuisance tripping when legacy thermal-magnetic breakers suffer from internal mechanism wear and calibration drift.
- Agitation: Sourcing exact-fit replacement circuit breakers for legacy GE switchgear lines without incurring massive lead times risks prolonged sub-distribution downtime.
- Solution: The GE SELA36AI0030 slides directly into standard Spectra bus compartments, providing reliable overcurrent protection and interrupting ratings to secure downstream motor control centers and feeder circuits.

4. Field Engineer’s Tech Notes
- Strap-On Connection and Torque Specs: When mounting this breaker to the panel bus stack, verify that the terminal mounting bolts are torqued precisely to OEM specifications using a calibrated wrench. Inadequate torque creates high-resistance contact points, leading to localized overheating under heavy load.
- Trip Unit Settings Configuration: Double-check the adjustable long-time, short-time, and instantaneous trip unit dial configurations against your coordination study before closing the main feed. Incorrect settings will compromise selective coordination hierarchies across the plant distribution grid.
5. Adaptive QA & Testing Protocol
Every inventory unit undergoes bench testing to validate hardware reliability prior to dispatch. For the SELA36AI0030 circuit breaker, our technicians execute secondary-injection testing using specialized current test sets to verify microprocessor trip unit response times, long-time delay accuracy, and instantaneous pickup thresholds across all 3 poles. Manual mechanical trip-test button actuation and main contact resistance measurements are performed to ensure uncompromised switching integrity. Complete test reports and pre-shipment functional verification videos are available upon request.
6. Buyer’s FAQ
- What is the standard warranty coverage for this circuit breaker?All units—whether New Surplus Factory Packed (NSFP) or fully tested/refurbished—carry a comprehensive 12-month operational warranty from the date of purchase.
- How fast can this breaker be shipped for emergency facility restorations?In-stock items ship the same business day if ordered before our daily carrier cutoff, with expedited global air delivery options available.
- Is this a direct physical replacement for older SE-frame GE breakers?Yes, the SELA36AI0030 fits standard Spectra series panelboard and switchboard interiors designed for SE-frame dimensions. Verify your interrupting capacity (AIC) requirements and bus configuration prior to installation.
