B-LINE BQL270 – Frequently Asked Questions
1) Is the BQL270 breaker rated for use on air conditioning and heat pump circuits?
Yes. The B-Line BQL270 is HACR rated, which is the rating an electrician looks for when a breaker feeds heating, air conditioning or refrigeration equipment with motor-compressor loads. If the unit's nameplate calls for an HACR type breaker, this one satisfies that requirement.
2) Is the BQL270 a plug-on breaker for a load center, or a bolt-in for commercial panelboards?
BQL270 is an Eaton BAB style thermal magnetic breaker. BAB is Eaton's bolt-on branch breaker family used in commercial panelboards, as opposed to the plug-on residential types, so the panel interior has to be prepped for bolt-on mounting. Confirm the interior your panel schedule calls for accepts BAB breakers before ordering.
3) What part number do I order for the B-Line BQL270 breaker?
Order it as BQL270, the manufacturer part number. It is an Eaton BAB style thermal magnetic circuit breaker, so if your panel schedule or existing breaker calls out a BAB type, BQL270 is the designation to quote.
4) What does thermal magnetic mean on the BQL270, and how does it protect a circuit?
Two separate trip mechanisms in one breaker. The thermal element responds to sustained overloads, heating a bimetal that trips after a time delay, which lets normal inrush pass without nuisance tripping. The magnetic element trips essentially instantly on a short circuit or ground fault level of current. That combination is what the BQL270 uses, and it is the standard behavior for branch circuit protection in panelboards.
