B-LINE QCFH2020T – Frequently Asked Questions
1) Is the QCFH2020T a two-pole 20 amp breaker, and what voltage is it rated for?
Yes. The QCFH2020T is a two-pole, 20 amp thermal-magnetic breaker rated 120/240 V, so it covers both a 240 V two-wire load and a 120/240 V multiwire branch circuit.
2) What wire size can I land on this Eaton QCF breaker?
The terminals take #14 through #4 AWG, cable-in/cable-out. Standard terminals are box type lugs, and they are also suitable for ring terminal connection on both line and load side, with a #10-32 terminal screw supplied.
3) Is this a plug-on panelboard breaker or does it wire in line and load?
It is a cable-in/cable-out device, meaning both the supply and the load conductors terminate on the breaker itself rather than the breaker plugging onto a panel bus. Plan the enclosure and conductor routing accordingly.
4) What are the dimensions of this QCF breaker for enclosure layout?
The breaker measures 4.6 in (length/depth), 3 in wide, 1.2 in high, and weighs .53 lb. Use those figures when checking gutter space and cover cutouts in a small enclosure.
5) Does a thermal-magnetic trip matter for motor or lighting loads?
Thermal-magnetic is the standard trip for general branch circuit protection: the thermal element handles sustained overloads while the magnetic element reacts to short circuits. It is not an electronic or adjustable trip unit, so the 20 amp rating is fixed.
