Eaton BQL3100 Circuit Breaker - 10 kAIC
Part Number: BQL3100
Quick Summary
The Eaton BQL3100 circuit breaker protects electrical panels by interrupting faults in commercial and industrial power circuits. These facilities often struggle with nuisance tripping and challenging bolt-on replacements in crowded switchgear. HACR rated compliance helps ensure safer operation across HVAC and motor-driven loads. Designed for three-pole service at 100 A with Cu/Al conductors, it integrates seamlessly into Eaton bolt-on frames. In practice, this combination delivers reliable protection, quick replacement, and predictable maintenance costs. The compact 5 in x 3 in x 3 in envelope and bolt-on mounting support fast, reliable installation in retrofit projects.
