B-LINE QCHW4100H – Frequently Asked Questions
1) What amperage and voltage is the Eaton QCHW4100H circuit breaker rated for?
The QCHW4100H is a 100A, 240V four-pole breaker with a thermal-magnetic trip. If your panel schedule calls for a 100 amp four-pole device at 240 volts, this is the rating it matches. Anything above 240V or a different pole count needs a different QC part.
2) Does the QCHW4100H land conductors directly, or does it need a bus connection?
It is a cable-in/cable-out breaker, so conductors terminate at the breaker on both the line and load side rather than plugging onto a panel bus. That makes it suited to enclosed or standalone applications where you are feeding through with cable. If your panelboard needs a bus-connected breaker, this is the wrong configuration.
3) Is the Eaton QCHW4100H UL Listed for use on a commercial or institutional job?
The QCHW4100H carries a UL Listed marking, which is what most inspectors and facility specs are looking for on an overcurrent device. The QCHW type is an industrial miniature circuit breaker, so it is intended for industrial and commercial distribution rather than residential load center use.
4) What are the physical dimensions of the QCHW4100H breaker for enclosure layout?
The breaker measures 5 in height, 3.8 in length/depth, and 1.2 in width, and weighs 3.1 lb. Use those figures when checking clearance behind a cover or laying out space in an enclosure.
5) What is the exact part number to order for this 100 amp four-pole Eaton QC breaker?
Order it as QCHW4100H. That is the manufacturer part number, covering the QCHW type, four poles, 100 amps, at 240V with a 22 kAIC interrupting rating. Adjacent QCHW numbers change the amperage or pole count, so the full string matters.
6) What does the thermal-magnetic trip on this QC breaker actually protect against?
A thermal-magnetic breaker uses two mechanisms: a bimetal element that trips on sustained overload and a magnetic element that trips fast on a short circuit. On the QCHW4100H that gives you both overload and short-circuit protection on all four poles in one device, with no electronic trip unit to set up.
