B-LINE QCHW2100H – Frequently Asked Questions
1) Is the B-Line QCHW2100H a 1-pole or 2-pole breaker, and what amperage?
The QCHW2100H is a two-pole, 100 amp Quicklag industrial breaker rated 240V. Two poles means it lands on both legs of a single-phase 240V circuit, so it covers loads like a large motor, a subpanel feeder, or a heating circuit rather than a 120V branch.
2) Will a QCHW breaker work on a 480V system?
No. The QCHW2100H is rated 240V, so it is for 120/240V single-phase or 240V three-phase systems only. For a 480V panel you need a breaker series rated for 480V; putting a 240V-rated device on 480V is not a legal or safe application.
3) How do the conductors land on this breaker - is it a bolt-on or plug-in?
The QCHW2100H is a cable-in/cable-out breaker. Both line and load terminate on lugs at the breaker itself rather than plugging onto a panel bus, which is how these industrial units get used as standalone disconnects, in enclosures, and at motor or equipment feeds.
4) Can the trip unit be changed to a different amp rating later?
No. The trip on this 100 amp Quicklag unit is non-interchangeable, so the 100A rating is fixed for the life of the breaker. If the load changes, you swap the whole breaker for the amperage you need rather than re-rating this one.
5) I need to match an existing breaker in a plant panel - what exactly should I order?
Order by the catalog number QCHW2100H. That designation encodes the QCHW industrial Quicklag type, two poles, and the 100 amp rating, with a 22 kAIC interrupting rating at 240V. Matching the full catalog number, not just the amperage, is what keeps the frame, trip, and terminations identical to what is already installed.
6) What does thermal-magnetic mean for how this breaker protects a circuit?
Two protection elements in one Quicklag unit: a thermal element that responds to sustained overload with an inverse time delay, and a magnetic element that trips instantly on a short circuit. That combination lets it ride through normal motor inrush while still clearing a bolted fault fast.
