Yes. The BQL220 is a bolt-on classic replacement designed to retrofit legacy BAB/BQL installations. It accepts Cu/Al wire up to #14-8 AWG and fits standard two-pole mounting footprints, allowing a straightforward swap without rewiring the panel. This minimizes downtime and preserves original electrical architecture while restoring protective functionality.
The BQL220 is a 20 A two-pole circuit breaker rated for 120/240 V with a 10 kAIC interrupt capacity. It supports Cu/Al wire sizes #14-8 AWG and carries HACR-rated protection. Its compact 5 in by 3 in by 2 in form factor and 0.5 lb weight facilitate easy handling and panel integration.
Industrial control panels, commercial equipment enclosures, and legacy electrical installations requiring reliable bolt-on protection benefit the most. The two-pole design suits multi-wire circuits, while the 10 kAIC interrupt rating provides robust fault handling in higher-energy environments, reducing downstream damage and maintenance costs over the equipment lifecycle.
The BQL220 carries HACR-rated protection, aligning with common building and electrical safety guidelines for reducing heat-related faults. While designed for reliable protection in 120/240 V circuits, users should verify site-specific regulatory requirements and follow manufacturer mounting and wiring instructions to ensure full compliance in their installation.
The BQL220 supports rapid retrofits with minimal panel disruption, reducing downtime costs during replacement. Its durable bolt-on design and high interrupt rating improve fault resilience, lowering repair frequency. Over the life of the system, consistent protection and straightforward sourcing of Cu/Al wiring parts contribute to a favorable return on investment.
