Eaton Quicklag QC Single-Pole Thermal-Magnetic Circuit Breaker, 120/240V

The Eaton Quicklag QC Single-Pole Thermal-Magnetic Circuit Breaker delivers dependable overcurrent protection for industrial electrical systems and panelboards. Rated 120/240V with a 10 kAIC interrupt rating, this Type QC industrial circuit breaker uses a thermal-magnetic trip mechanism to protect single-pole circuits from sustained overloads and high fault currents. Its non-interchangeable design and cable-in/cable-out connection make it a practical choice for facilities and contractors that need code-compliant, reliable circuit protection on industrial-grade panelboards. Eaton engineers the Quicklag QC series for consistent trip performance across the demanding conditions common to industrial and commercial electrical distribution equipment.

Key Features

  • Connection Type: Cable-in/cable-out connection simplifies wiring and supports straightforward panelboard installation without special adapters.
  • Voltage Rating: 120/240V rating supports standard industrial and commercial branch-circuit voltage requirements.
  • Interrupt Rating: 10 kAIC interrupt rating provides dependable protection against high fault currents, helping safeguard downstream equipment and wiring.
  • Trip Type: Thermal-magnetic trip mechanism responds to both sustained overloads and instantaneous short-circuit conditions for well-rounded circuit protection.
  • Poles: Single-pole configuration is sized for dedicated, single-phase circuit protection within an industrial panelboard.
  • Circuit Breaker Type: Quicklag Type QC construction is purpose-built for industrial circuit breaker applications.
  • Options: Non-interchangeable design helps maintain the intended breaker configuration within the panelboard for added installation security.
  • Switching Duty: Rated for 120V fluorescent lighting applications per Eaton catalog notes, making it suitable for lighting circuit switching duty.

Eaton QC1010 – Frequently Asked Questions

1) What amperages does the Eaton Quicklag QC single-pole breaker come in?
Five ratings are offered on the QC single-pole: 10A (QC1010), 15A (QC1015), 20A (QC1020), 30A (QC1030) and 40A (QC1040). All share the same 120/240V rating, 10 kAIC interrupting capacity and thermal-magnetic trip, so you pick strictly on the branch circuit conductor size and load.
2) Will a Quicklag QC breaker fit in my Eaton load center or any standard panel?
No, not a residential load center. The Quicklag Type QC is an industrial panelboard breaker with a cable-in/cable-out connection, meaning line and load land on lugs on the breaker rather than plugging onto a bus stab. It also carries a non-interchangeable design, so it is meant to go back into equipment built for Type QC. If your panel takes plug-on breakers, this is the wrong family.
3) I need to replace a failed breaker in an existing Quicklag panelboard. How do I order the right one?
Match the amperage of the breaker coming out and order the corresponding QC catalog number: QC1010, QC1015, QC1020, QC1030 or QC1040. Because the QC is a non-interchangeable design with cable-in/cable-out terminations, a same-family replacement drops back into the same position and lands on the same conductors without adapters. Do not step the amperage up to stop nuisance tripping; the breaker is sized to the wire.
4) Can I use this breaker to switch fluorescent lighting circuits on and off?
Yes. The Quicklag QC carries a switching-duty rating for 120V fluorescent lighting, so it can be used as the manual on/off means for a lighting circuit rather than purely as overcurrent protection. That rating applies at 120V fluorescent loads; a breaker without SWD marking should not be used that way.
5) How much space does an Eaton QC breaker take up in the panel?
Each single-pole QC measures 4.8 inches by 1.2 inches. Use the 1.2 inch dimension when you are counting how many will line up in the available mounting space, and confirm the 4.8 inch dimension clears within your panelboard interior before you order a run of them.
6) Can I use a single-pole QC breaker on a 240V two-wire circuit?
The single-pole QC is rated 120/240V, and the 240V half of that rating means it is suited to one pole of a 120/240V system. A straight 240V two-wire load needs both ungrounded conductors opened together, which takes a two-pole device. A single pole here protects a 120V branch circuit.
7) Does the Eaton QC breaker provide ground-fault or arc-fault protection?
No. The QC is a thermal-magnetic overcurrent device only, covering overload and short circuit. If the circuit requires GFCI or AFCI protection for the occupancy, that has to come from a dedicated GFCI/AFCI breaker or a receptacle-level device.
8) What does the thermal-magnetic trip on the Quicklag QC actually protect against?
Two different faults, with two different mechanisms in one breaker. The thermal element (a bimetal) responds to sustained overload, letting a modest over-current run briefly (motor inrush, lamp ballast startup) before tripping. The magnetic element trips instantly on a bolted short circuit. That is why one breaker covers both a slowly overloaded conductor and a dead short without nuisance tripping on normal inrush.
