B-Line BQL225 Eaton BAB thermal magnetic circuit breaker

The BQL225 is a BQL-type replacement breaker built as an Eaton BAB thermal magnetic circuit breaker, so it is intended for panels that accept that BAB/BQL footprint. It is a two-pole 25A device rated 120/240 V with a 10 kAIC interrupting rating at 120/240 Vac. Confirm your panel's label calls for BAB or BQL type breakers before installing.

Lug capacity on the BQL225 is #14 to #8 AWG, and it accepts either copper or aluminum conductors. For a 25A two-pole circuit that covers the usual 10 AWG copper run comfortably, with room up to 8 AWG if the run length or derating pushes you larger.

Yes. The BQL225 is HACR rated, which is the marking required when a breaker feeds heating, air conditioning, or refrigeration equipment with group motor loads. At 25A two-pole on 120/240 V it suits a condenser or air handler whose nameplate calls for a 25A maximum overcurrent device. Always size to the equipment nameplate MCA and max fuse/breaker values, not to the wire alone.

That is exactly what it is sold as, a classic replacement circuit breaker in the BQL family. Match three things off the breaker you are pulling: 25A rating, two-pole, and 120/240 V. If the old breaker carries a higher interrupting rating than 10 kAIC, or the panel label calls for a different breaker type, this one is not the swap.

The BQL225 is rated 10 kAIC at 120/240 Vac, which covers typical residential and light commercial panels where available fault current at the panel is under 10,000 amps. On a service close to a large utility transformer, or downstream of a high-capacity switchboard where the fault current study shows more than 10 kA, you need a higher AIC device or a series-rated combination. The 10 kAIC figure is the limit, not a recommendation.

Two-pole construction means the BQL225 lands on both legs of a 120/240 V panel and trips both poles together, so it serves one 240 V load (or a 120/240 V load such as a dryer or range) at 25A. If you need two independent 120 V circuits, a two-pole breaker is the wrong choice, use two single-pole breakers instead.

Thermal magnetic is standard overcurrent protection only: a bimetal element handles sustained overloads and a magnetic element clears short circuits instantly. The BQL225 is that type of device, so it does not provide GFCI or AFCI protection. Where code requires ground fault or arc fault protection for the circuit, you need a GFCI or AFCI breaker or a protected receptacle instead.

Shipping dimensions on the BQL225 are 5 x 3 x 2 inches and it weighs half a pound. As a two-pole unit it occupies two adjacent single-pole positions in the panel interior, so you need two open spaces on the same bus stack.

Order it as BQL225. That is the manufacturer part number for the B-Line 25A two-pole Eaton BAB thermal magnetic breaker, and it is the only model on the item, so there are no finish or trim options to specify.
