B-LINE QHCX1030 – Frequently Asked Questions
1) What amperage and voltage is the Eaton QHCX1030 circuit breaker rated for?
The QHCX1030 is a 30A single-pole miniature breaker rated 120/240 V. Single-pole means it lands on one bus stab and gives you one 120 V circuit off a 120/240 V panel; a 240 V load needs a two-pole device instead.
2) Does the QHCX1030 have a high interrupting rating for a high fault-current service?
Yes. It carries a 42 kAIC interrupting rating, which is what the QHCX family is for: panels fed by a service or transformer with available fault current above what a standard 10 kAIC residential breaker can clear. If your short-circuit study calls for 42 kA at the panel, this is the breaker that matches it.
3) Will a QHCX breaker fit any Eaton load center?
The QHCX1030 is an Eaton QC-type, QHCX high-interrupting breaker, so it goes in panels and load centers built to accept the QC/QHCX family. It is not a universal or classified breaker, so check the breaker-type label inside your panel door before ordering. Dropping a QHCX into a bus not rated for it defeats the 42 kAIC rating.
4) Can I use the QHCX1030 to replace a standard 30A single-pole breaker in the same panel?
Only if the panel is built for QC/QHCX breakers. The QHCX1030 matches a standard 30A single-pole on amperage and on 120/240 V rating, and it raises the interrupting capacity to 42 kAIC, so it is a common swap where a fault-current calculation came back higher than the installed breakers could handle. Matching the panel's breaker type is the deciding factor, not the amperage.
5) What does thermal-magnetic trip mean on this 30A QC breaker, and what does it protect against?
The QHCX1030 uses a thermal-magnetic trip element. The thermal half is a bimetal that responds to sustained overload, so it rides through normal inrush but opens on a circuit drawing over 30A for too long. The magnetic half is instantaneous and clears a hard short. It is standard overcurrent protection, not ground-fault or arc-fault sensing, so a circuit needing GFCI or AFCI protection needs a different device or a downstream receptacle.
6) What is the exact part number to order for the 30A high-interrupt QC breaker?
Order by manufacturer part number QHCX1030. That single number carries the whole spec: QHCX series, single pole, 30 amps.
