Question: I'm dropping this into the forum for others searching in the future via google or whatever_Eaton Australia says:The Quicklag range of miniature circuit breakers was originally released in Australia by Email-Westinghouse in 1957 before the company changed its name to Cutler-Hammer and then to Eaton.----Most of the Quicklag line is no longer available for sale. Eaton Descriptive Bulletin FTC-100M3 describes the Quicklag® Residential series as Type BR. There's no note about equivalence, they just call them Type BR. The dimensions match the modern Type BR to the millimeter.---Current marketing materials for certain lines still use the QuickLag trademark: "Eaton BR thermal magnetic circuit breaker,Quicklag Type BRHX circuit breaker".--This implies that QuickLag legacy lines like QuickLag P and QuickLag PL may have evolved into the Eaton BR.
This is a helpful bit of information for anyone trying to figure out what replacements are available for older Eaton/Westinghouse/Cutler-Hammer Quicklag circuit breakers in Australia. Here's a slightly more organized summary, highlighting the key takeaways
Key Takeaways Regarding Eaton Quicklag Circuit Breakers in Australia:
Historical Context
The Quicklag line was first introduced in Australia by Email-Westinghouse in 1957 and subsequently rebranded through Cutler-Hammer to Eaton.
Obsolescence
Most of the original Quicklag line is no longer available for sale.
Quicklag = Type BR (Residential Series)
Eaton Descriptive Bulletin FTC-100M3 identifies the Quicklag® Residential series as equivalent to the modern Eaton Type BR. The physical dimensions also align.
Ongoing Trademark Use
The "Quicklag" name is still used in marketing certain Eaton BR circuit breaker lines. Example: "Eaton BR thermal magnetic circuit breaker,Quicklag Type BRHX circuit breaker".
Possible Evolution
Older QuickLag series like QuickLag P and QuickLag PL may have evolved into the Eaton BR series. This isn't stated explicitly, but it's a reasonable inference based on the information.
Important Considerations and Caveats
Verify Compatibility
Always verify the specific electrical characteristics (voltage, current, breaking capacity) of the replacement Type BR breaker with the original Quicklag breaker and the existing electrical system before installation. Do not rely solely on physical dimensions.
Consult a Qualified Electrician
Electrical work should only be performed by a licensed and qualified electrician. They can assess the existing system and ensure that any replacement breakers are suitable and installed correctly and safely.
Local Regulations
Ensure that any replacement circuit breakers comply with all applicable Australian electrical standards and regulations.
"May Have Evolved" is NOT Definite: The statement that QuickLag P and QuickLag PL may* have evolved into BR means that specific confirmation is required. Don't assume direct compatibility without checking.This information provides a useful starting point for researching replacement options. Thanks for sharing! Flag for review
