BQL220

The BQL220 is a 2‑pole, 20 amp thermal‑magnetic circuit breaker designed for use in Eaton/Cutler‑Hammer B‑type load centers and panelboards. It provides branch‑circuit protection against overloads and short circuits in residential and light commercial electrical distribution systems. The breaker’s compact plug‑in design allows it to occupy just one breaker space per pole, making it suitable for standard load centers where reliable overcurrent protection is needed for lighting, receptacles, or appliance circuits.

Electrically, the BQL220 employs a thermal‑magnetic trip mechanism, combining heat‑sensitive overload protection with magnetic instantaneous trip response for fast interruption of high‑fault currents. It is rated for 120/240 V AC operation with a typical interrupting capacity of 10kA@240V, meaning it can safely interrupt fault currents up to 10,000 amps at its rated voltage without damage in properly designed systems. This makes the breaker suitable for general purpose branch‑circuit protection in typical residential panelboards as well as commercial spaces with moderate load demands. The breaker’s common‑trip linkage ensures both poles trip together, protecting multi‑wire branch circuits from dangerous imbalance conditions.

Mechanically, the BQL220 features a molded thermoset case and an easy‑to‑operate manual toggle for ON/OFF control and reset after a trip event. The breaker is UL 489 listed and meets applicable North American safety standards for low‑voltage circuit‑protection devices. It accepts standard conductor sizes compatible with B‑type panelboards and integrates seamlessly with Eaton’s accessory ecosystem for labeling and auxiliary contacts where needed. Because of its widespread compatibility and dependable performance, the BQL220 is often used as a replacement or new installation breaker in Eaton‑brand load centers requiring dependable 20 amp protection.
