B-LINE QCHW2045 – Frequently Asked Questions

1) Does the QCHW2045 circuit breaker land wire directly, or does it plug onto a panel bus?
It is a cable-in/cable-out device, so conductors terminate on both the line and load sides of the breaker itself. That makes it suited to enclosed or standalone industrial applications rather than dropping onto a loadcenter bus stab. Plan your raceway and conductor entry accordingly, because there is no bus connection to rely on.
2) What size load will a 45 amp two-pole Quicklag QCHW breaker protect?
The QCHW2045 is a two-pole, 45 amp device rated 120/240 V, so it protects a 240 V line-to-line load such as a compressor, heater, or feeder to a small subpanel. Both poles trip together on a fault on either leg. For a 120 V single-phase branch circuit you would want a single-pole device instead.
3) Is the QCHW2045 thermal-magnetic or electronic trip?
Thermal-magnetic. The bimetal element handles sustained overloads with an inverse time delay, and the magnetic element clears short circuits instantaneously. That combination tolerates normal motor inrush without nuisance tripping, which is why it is specified on industrial branch circuits.
4) What are the dimensions of the QCHW2045 breaker for enclosure layout?
The published dimensions are 5 in, 3 in, and .6 in, with a product weight of 3 lb. Use the .6 in figure when you are counting pole spacing in an enclosure, since the two-pole device occupies its poles side by side.
