Product FAQs
7 answersIs the Westinghouse QCL1015 still manufactured, or is there a direct replacement?
The QCL1015 is a legacy component. Eaton recommends the QC1015 as the modern substitute, which offers identical electrical specifications for cable-in/cable-out applications.
Is the QCL1015 manufactured by Westinghouse or Eaton?
The Quicklag QCL series was originally developed by Westinghouse. Eaton acquired the Westinghouse electrical distribution business in 1994, so these breakers may be branded as Eaton, Cutler-Hammer, or Westinghouse depending on their date of manufacture.
What type of enclosures are compatible with the QCL1015?
This breaker is designed for use in Eaton Quicklag enclosures and OEM control panels that support unit mount configurations.
Can the QCL1015 be used in DC control circuits?
Yes, this breaker is rated for DC applications. It provides a 5kA interrupting capacity at 24VDC and 48VDC, and a 3.8kA interrupting capacity at 62.5VDC.
What wire sizes are accepted by the terminals on this breaker?
The box lugs on the QCL1015 accept wire gauges ranging from 14 AWG to 10 AWG.
How does the thermal-magnetic trip unit operate on this breaker?
It utilizes a fixed thermal element for long-time overload protection and a fixed magnetic element for instantaneous short-circuit protection.
Does this breaker plug directly onto a panelboard busbar?
No, the QCL1015 is a unit mount breaker. It uses a bolt-on connection with box lugs on both the line and load sides for cable-in/cable-out installations, rather than plugging onto a standard load center busbar.
