The QDM32100TN is a reliable Square D 3-Pole Circuit Breaker designed to handle 100A at 240V. Ideal for commercial and residential applications, this durable breaker ensures optimal protection for your electrical systems. Its compact design allows for easy installation, making it a perfect choice for upgrading or replacing existing breakers.
The QDM32100TN is a bolt-on frame breaker intended for Square D QDM-series panelboards and compatible commercial loadcentres. It is not a plug-in breaker and will not fit standard QO or Homeline residential loadcentres. If you're unsure whether it fits your board, contact our team with your panel model number and we'll confirm.
Square D QDM-series breakers can be difficult to find through standard channels. Northern Breaker Group specializes in obsolete and hard-to-find breakers — if the QDM32100TN is no longer in active production, we source verified replacements or new-old-stock units. Reach out for a quote and availability check.
The QDM32100TN is rated for 240V maximum and 3 poles, making it suitable for use on 240V single-phase or certain 208V/240V three-phase systems, provided the panel and application match those voltage ratings. Always verify the system voltage, available fault current (≤25kA), and local code requirements — or ask our technical team for guidance.
